Introduction of communication author

Professor Yu Kai

Shanghai Jiao Tong University

The main research direction is the research and industrialization of interactive artificial intelligence, speech and natural language processing and machine learning.

Speech synthesis is one of the key issues to realize human-computer interaction. Yu Kai’s team from the Cross-media Speech Intelligence Laboratory of Shanghai Jiaotong University recentlyApplied SciencesIn this paper, an end-to-end speech synthesis method based on acoustic word embedding is studied.

introduction

In recent years, the end-to-end text-to-speech synthesis (TTS) model based on sequence-to-sequence generation architecture has achieved great success in generating natural speech. In order to avoid frame-by-frame decreasing, unnatural TTS models, such as FastSpeech and FastSpeech2, are proposed to improve the speed of speech generation. However, vocabulary recognition is very important for TTS systems to generate highly natural speech, but most end-to-end TTS systems only use phonemes as input markers, ignoring the information of which vocabulary phonemes come from.

Previous studies used preset language words to embed phoneme sequences as the input of TTS system. However, because language information is not directly related to how words are pronounced, the embedding of these words hardly affects the improvement of TTS quality. In this paper, a word acoustic embedding method combined with TTS system is proposed. Experiments on LJSpeech data set show that the acoustic embedding of words significantly improves the likelihood of prosodic prediction of sonic level on training set and verification set. The subjective evaluation of the naturalness of synthesized audio shows that the system with acoustic word embedding is obviously superior to the pure TTS system and other TTS systems with preset word embedding.

design highlights

1. Propose an end-to-end TTS system based on Acoustic Word Embedding (AWE) joint training to help improve rhythm and naturalness;

2. Using the prosody modeling method based on GMM to objectively measure the prosody of synthesized audio;

3. Explore the best structure of word encoder and the best threshold of word frequency screening;

4. Subjective evaluation after the test shows that AWE is more natural than pre-trained word embedding.

End-to-end speech synthesis method based on acoustic word embedding

Part1: end-to-end speech synthesis

In this paper, FastSpeech2 is selected as the acoustic model, but prosody modeling is not explicitly considered, which makes it difficult to objectively evaluate the prosody prediction performance of TTS system without subjective listening test. Based on this, a phoneme-level prosodic prediction module is introduced into the model, which can predict the prosodic embedding distribution of each phoneme autoregressively. Compared with the standard Fastspeech2 system, it can not only improve naturalness, but also allow the logarithmic likelihood of prosodic embedding to easily and objectively evaluate the prosodic prediction performance at phoneme level, as shown in Figure 1.

Figure 1. End-to-end speech synthesis based on GMM prosody modeling.

Part2: Acoustic Word Embedding

Nowadays, most popular TTS systems use phonemes as sound input markers, ignoring the information of which vocabulary phonemes come from. However, vocabulary recognition is very important for TTS system to generate highly natural speech. In this paper, acoustic word embedding is proposed to synthesize natural speech, and a word encoder and a word phoneme aligner are introduced into the traditional TTS system. The architecture is shown in Figure 2.

Figure 2. Model architecture with acoustic word embedding.

Experimental setup and results

1. Experimental setup

The TTS model in this paper is based on Fastspeech2 (GMM prosodic modeling). The number of Gaussian components in GMM is set to 20, and Adam optimizer and Noam learning rate scheduling strategy are used for TTS training. The researchers used 320mel-spectrogram as acoustic features, with a frame shift of 12.5ms and a frame length of 50 ms.. MelGAN is used as vocoder to reconstruct waveform.

2. Word encoder architecture

The performance of three common word encoder structures is compared.

(1) None: the baseline of the word encoder is not used;

(2) BLSTM；: a layer of 512-dimensional bidirectional LSTM;

(3) Transformer: 6-layer 512-dimensional transformer module;

(4) Conv+Transformer: one layer of 1D-CNN with a core size of 3, followed by six layers of 512-dimensional Transformer module.

Table 1. Parameter number and reasoning speed of various encoder architectures (sec/frame).

3. Word frequency threshold

Table 2. Vocabulary and OOV under different word frequency thresholds.

conclusion

In this paper, an innovative method of directly training acoustic embedding of words in TTS system is proposed. The phoneme sequence and the word sequence pass through two encoders respectively, which are used as the input of TTS system together, and then the two output hidden states are spliced together for phoneme-level prosodic prediction. Experiments on LJSpeech data set show that the superposition structure of convolution and Transformer is the best for word encoder. In addition, the selection of word frequency threshold should be cautious, too large or too small threshold will lead to performance degradation. Finally, this paper compares the proposed system with several works that do not use the baseline of lexical information and use pre-trained words to embed. The subjective listening test shows that the system proposed in this paper is superior to all other systems in naturalness.

In the 6th Tianjin People’s Satisfied Selection of Good Doctors, Nurses and Hospitals jointly organized by Tianjin Health and Wellness Commission, Municipal Civilization Office and Municipal Federation of Trade Unions, Jiu San SocietyGao Xiang, chairman of the branch of Tianjin Fifth Central Hospital, was awarded the satisfaction of Tianjin people.The title of "good doctor".

As a doctor, Gao Xiang adheres to the professional spirit of "respecting life, saving lives, being willing to contribute, and loving the country without borders". He is skilled in his business and dedicated to his post. Because of his outstanding work performance, he has also been awarded the title of Tianjin Dedicated Good Man, Binhai New Area Dedicated Moral Model and Tianjin Municipal Health Planning Commission’s fourth post training technical competition technical expert.

1997He joined the Fifth Central Hospital of Tianjin in, and Gao Xiang started as an intern.twentyAfter years of hard work and hard work, he is now the director of the medical department of Tianjin Fifth Central Hospital and the deputy director of orthopedics administration. Gao Xiang has many identities, such as a member of the Foot and Ankle Surgery Group of the Orthopedic Branch of the Chinese Medical Association.SICOTStanding Committee member of China Department of Foot and Ankle Medicine, member of China Research Hospital Association Foot and Ankle Medicine Professional Committee, etc., but he is most proud of the satisfaction of the sixth Tianjin people.The title of "good doctor" Because he always felt that doctors serve the broad masses of the people, and it is the highest honor to be recognized by the people.

When he was a child in Gaoxiang, his father once said to him"The profession of doctor can help others to avoid pain, which is a respectable profession." Since then, he has been determined to be a doctor to help others at a young age. But it was many years later that he really understood the meaning behind the word "doctor".2001In, Gao Xiang was atPLA 89 HospitalFurther study in the Institute of Microsurgery. One day when I was on duty, I met a 19-year-old boy. His left calf was damaged and the situation was very serious. On the same day, the doctor group on duty decided to have an amputation operation, and after explaining the illness and treatment plan to the child’s father, the child’s father immediately cried. Just then, Gao Xiang’s teacher, Professor Zhang, happened to pass by. After asking about the situation, he carefully looked at the patient and made a surprising decision. He wanted to save the child’s limbs. Everyone thinks that this is too difficult, and it can’t be achieved with the existing technical level. But Professor Zhang said it doesn’t matter, he will be the chief surgeon. Gao Xiang asked him at that time: "You are not on duty today, why do you have to work so hard and take such a big risk?" Professor Zhang said earnestly, "What was our initial intention as a doctor? Isn’t it just to use what you have learned to help patients relieve their pain? It is worthwhile to pay a little hard but save a family. " Because of the high difficulty, the operation takes a long time. Finally, after 72 hours, Professor Zhang finally succeeded in saving the calf for the patient and created a medical miracle. After this incident, Gao Xiang really understood his father’s words when he was a child, and also understood that to become a qualified doctor, besides excellent skills, he should have an angel-like heart, a sea-like mind and the courage to overcome difficulties.

Since then, Gao Xiang has always adhered to the professional spirit of "the heart of the doctor’s parents". He is conscientious in his work and never cares about personal gains and losses. Sometimes there are many surgical patients, and he can’t get off work normally from 9: 00 in the morning until 11: 00 in the evening. He never complains, and he often sacrifices his weekend break to visit patients in Corey, with no regrets. Over the years, his selfless and caring attitude towards patients has never changed, and he has been praised by the majority of patients and colleagues.

2010In, the Department of Orthopaedics of the Fifth Central Hospital of Tianjin was divided into specialties, and Gao Xiang was the head of the Foot and Ankle Department. There were only three people in the whole department, with few personnel and heavy tasks. In this case, he resolutely took the lead. That year, he was hospitalized for surgery for osteoid osteoma of ilium and returned to work one month after operation. Due to the short postoperative time, he did not fully recover, and after some complicated and long-term operations, he would have lower limb pain and could not stand. In order to ensure the therapeutic effect of patients, Gao Xiang often begged the anesthesiologist to give himself a nerve block before the operation to relieve the pain and ensure the smooth completion of the operation. This situation lasted for more than three weeks, and colleagues around him advised him to pay attention to his health, but he always laughed it off and said, "It doesn’t matter if it hurts, the patient needs me." That’s it. With his efforts and drive, the professional level of the Department of Orthopedics, Foot and Ankle in Tianjin Fifth Central Hospital has developed rapidly. In January 2015, the hospital established the foot and ankle surgery diagnosis and treatment center, which features foot and ankle surgery, and the treatment of traumatic osteopathy of foot and ankle is at the leading level in Tianjin.

2019On January 1, 2008, when thousands of people were celebrating the New Year, Gao Xiang was sent to the outer court for consultation with a patient with a broken lower limb. When he saw the patient’s injured calf, he couldn’t help thinking of his teacher and the past that he could never forget. Therefore, he gave up the time to reunite with his family, immediately escorted the patient to the Fifth Central Hospital, and urgently opened a green channel to perform replantation surgery for the patient. After a night of hard work, the patient’s calf was finally saved, which brought hope to this family.

2020At the beginning of 2008, Gao Xiang just took over the work of the medical department of the Fifth Central Hospital of Tianjin, and the epidemic occurred. The Medical Department is the lead department of the whole prevention and control work. In accordance with the instructions of the hospital leaders, Gao Xiang comprehensively arranged the epidemic prevention and control work of the hospital, including arranging medical teams to assist Wuhan and Haihe Hospital; Construction of fever clinic in hospital; Pre-examination and triage, outpatient and emergency treatment, hospital management and a series of tasks. In order to better complete the task, ensure that the epidemic prevention work is in place, and at the same time ensure the medical needs of the majority of patients and the treatment of acute and critical diseases, Gao Xiang, who just took over the medical department, often works around the clock. Under his leadership, the prevention and control and normal diagnosis and treatment work of Tianjin No.5 Central Hospital were carried out in an orderly manner. At the beginning of the epidemic, nucleic acid testing was carried out, becoming one of the first five nucleic acid testing laboratories in Tianjin, and then the Fangcang nucleic acid laboratory was established. At present, the daily detection volume can reach 2,000, which is the smooth epidemic prevention work in the new During the epidemic prevention and control work, Tianjin Fifth Central Hospital achieved no missed diagnosis, no misdiagnosis and zero infection among medical staff, which was highly recognized by the municipal and district health and health committees.

"Work hard and wait for no one." It’s Gao Xiang’s favorite sentence. Over the years, he has been adhering to this concept in his life and work, and always regards the medical service for the people as his greatest responsibility and highest mission.(Jiu San Xue)She Binhai New Area District Committee Zhou Wu)

　　In the past two years, people have been enthusiastic about skiing, but before that, skiing was still a very minority sport in China. However, nowadays, with the popularity of skiing culture, especially since the successful bid for the Winter Olympics, skiing has entered the public’s field of vision, and there are more and more snow fields in the country. Looking at all kinds of great gods galloping on the snow field on the internet, can’t you help but be eager to try? Let’s go skiing together today. The competition time of the Winter Olympics is coming to an end, and many wonderful competitions have been watched. The skiing events of the 2022 Winter Olympics include: platform skiing, freestyle skiing, alpine skiing, cross-country skiing, nordic combined and snowboarding. In order to let you watch the race better and participate in skiing, the author brings you today’s article.

　　First, distinguish skiing events to help you watch the race better.

　　There are many skiing events in this Winter Olympics. In order to watch the games better, let’s learn about the events first. The names of each event list can’t be clearly distinguished. Skiing events are divided into snowboarding and snowboarding in terms of the number of skateboards. The following is a detailed introduction:

　　1. Double board skiing:

　　(1) Ski jumping and freestyle skiing-skill events

　　In order to fly farther and score higher, the skiers need to have super skills to fly farther.

　　The greater the technical difficulty of freestyle skiing, the higher the score. The freestyle skiing in this Winter Olympics consists of seven events: aerial skills, snow skills, obstacle chasing, U-shaped field skills, slope obstacle skills, big platform, and aerial skills mixed groups.

　　Gu Ailing’s advantage event is the skill event. She participated in three events in this Winter Olympics, namely, slope obstacle skill, U-shaped field skill and big platform jump.

　　(2) Alpine skiing and cross-country skiing-speed events

　　There are many flag gates on the track of alpine skiing, and athletes need to cross them.

　　Cross-country skiing is like a ground marathon, which requires great endurance and physical strength.

　　(3) nordic combined-Comprehensive Project

　　This is a competition for men only, which lasts for 2 days. On the first day, I competed in platform skiing and on the second day, I competed in cross-country skiing.

　　2. snowboarding

　　Snowboarding is divided into racing category and skill category. Racing categories include: parallel slalom, obstacle chase, obstacle chase round group. Skills include: U-shaped court, obstacle breaking skills and big platform jumping.

　　Second, how can the public prevent skiing injuries?

　　With the east wind of Beijing Winter Olympics, this winter, the atmosphere of ice and snow is getting stronger and stronger, and more and more people are participating in this sport, and this sport has brought a lot of damage to the public. According to relevant surveys, mass skiers have more knee joint injuries, such as tearing and injury/strain of ligaments around the knee joint; In addition, there are many injuries to the head and neck, upper limbs and thumb. If you want to effectively avoid injury, you are advised to do the following:

　　Step 1 wear protective gear

　　Wear helmet and joint protection when skiing.

　　2. Make full preparations.

　　Full warm-up can make the body get high-efficiency physiological requirements and reduce the occurrence of injuries. Here are some professional skiing warm-up exercises to help you get into the state as soon as possible:

　　(1) Warm-up of lower limbs

　　Action 1: Lie on your back and lift your legs

　　Lie on your back on the mat, first do hip extension under the condition of leg flexion and straight leg, then do adduction and abduction under the condition of leg flexion, and then do hip rotation exercises under the condition of leg flexion. Finally, under the conditions of supine and prone, the touch exercise of the opposite hand and foot was carried out. The schematic diagram is as follows:

　　Action 2: Hip flexor stretching

　　Stretching hip muscles can reduce hip muscle tension and increase hip flexibility. Kneel with legs apart, keep the trunk straight, slowly move the center of gravity forward, and tilt the upper body to the side of the front support leg. The schematic diagram is as follows:

　　Action 3: lateral box jumping

　　Practicing this movement can improve the control ability of hips and knees. Jump sideways from the box and keep your hips, knees and ankles aligned when landing. Increase the difficulty of action by swinging your arm or jumping a longer distance. The schematic diagram is as follows:

　　(2) Warm up the core parts of the body

　　Action 1: Static force of split leg side brace

　　Practicing this movement can improve core strength and prevent injury. Elbow support, lift your body, keep it straight, raise your upper legs to the limit, lower your body to the starting position, and then do the next exercise. For 30 seconds in each group, practice 3 groups. The schematic diagram is as follows:

　　Action 2: Start at both ends.

　　Lie prone on the mat, lift and extend your arms and legs, tighten your shoulder blades, then put them down and repeat the exercise. The schematic diagram is as follows:

　　(3) Turn to warm up

　　Action 1: Kneeling and turning

　　Turning exercises can help improve the flexibility of the trunk. Kneel on your knees, turn to your sides respectively, and touch your feet on the other side with your hands. The schematic diagram is as follows:

　　Action 2: Thoracic Spine Rotation

　　Hands on the ground, kneeling on the mat. Keep the pelvis still, and one arm drives the upper back to rotate. When practicing, keep your eyes on your arms and swing them. For 20 seconds in each group, practice 3 groups. The schematic diagram is as follows:

　　Step 3 learn to fall

　　All kinds of accidents are most likely to occur in ice and snow sports. Learn how to fall safely to better protect yourself.

　　Double board: When the speed can’t be controlled during sliding, if you want to avoid falling, you can first try to lean forward and make a plow brake (make the tail of the double board open in a "V" shape during sliding); If you can’t brake or if you can’t slow down, you should take the initiative to fall down: throw away the poles, hold your body with your hands, squat down and fall to one side of your body, land with your ass, and remember to forbid hand support! (Hand support is easy to cause wrist fracture)

　　Veneer: when sliding on the front edge, it is easy to fall forward. At this time, you should kneel down with your legs, lower your center of gravity, and stretch your hands forward as far as possible. The whole person is kneeling on the ground and lifting the snowboard. When the rear blade slides and falls, you should cross your arms on your chest, squat down with your legs to form a ball, roll back with your back on the ground, and lift the snowboard at the same time. Also remember to ban hand support!

　　4. Other precautions

　　(1) Avoid skiing due to fatigue or discomfort. Skiing consumes a lot of physical energy, and it is easy to cause injuries under fatigue.

　　(2) Skiing should be studied step by step, and there should be no psychology of being competitive and eager for success.

　　(3) Choose a suitable ski trail, and don’t blindly climb the advanced ski trail as soon as you learn to ski.

　　Third, how to choose ski equipment?

　　Step 1 snowboard

　　For beginners, it is most convenient to rent ski equipment directly in the ski resort. You should also know the following points when choosing ski gear:

　　(1) The longer the length of the snowboard, the greater the speed, the more difficult it is to ski, and the more difficult it is to control.

　　(2) For beginners, the length of skateboard should be 20-30cm less than the height. For amateurs, snowboarding is generally lower than the height, easier to operate, more flexible in steering and easier to use.

　　(3) You can choose a relatively soft and elastic skateboard. The skateboard with great elasticity will not be too fast, and it is easier to control, so it is safer.

　　2. Ski suit

　　You should choose a ski suit with the right size, so you can move freely. First of all, choose warm, waterproof and windproof fabrics. Secondly, it is ok to wear a ski suit and a jumpsuit, but when choosing, the pants must be high-waist; Clothes and trousers with adjustable cuffs and cuffs can effectively prevent snow from entering. Finally, it is best to choose eye-catching tones that have a color difference with white to avoid collision accidents.

　　It is suggested to adopt the "sandwich" dressing method: quick-drying clothes/sweat-wicking underwear+warm middle layer+windproof and waterproof/professional ski coat to achieve the effect of sweating inside, keeping warm in the middle and waterproof outside.

　　Choosing professional ski shoes can effectively keep warm and prevent injuries. When choosing ski shoes, it is best to try them on the spot. The most comfortable state is to let the feet have room to move inside the boots, but the sides of the ankles should not be loose. The back of the shoes should be strong and have certain endurance; Ensure that the calf can bend forward flexibly.

　　In addition, ski masks, warm hats, ski gloves, ski socks, etc. should be prepared.

　　3. Accessories and protective gear

　　Ski pole, the ideal length is that when a person stands upright, the arm holding ski pole can touch the ground vertically at a 90-degree angle. Ski helmets should not be too tight or too loose after wearing. It is best to rent or buy them after trying them on the spot. Ski goggles, it is recommended to choose a fully enclosed ski goggles with thicker frame and anti-fogging.

　　In addition, beginners are advised to wear joint protection and anti-fall pads.

Text/Technology Talk

This year’s Double Eleven is coming to an end, but the situation is quite different from previous years.

Not to mention the overall sales level and too many recipes, this year’s double promotion of the 11th National Congress of the Communist Party of China is destined to be uneventful. The head of the live streaming host is controversial, and the small and medium-sized live streaming hosts have begun to show their superpowers; originally belonging to Ali and JD.com’s "two people turn", Douyin, Pinduoduo and other heavy players have made the situation even more chaotic…

Under the surging undercurrent, there is also a pair of mysterious big hands playing an important role, that is, AI. It is concentrated in the fact that AI no longer only plays a role in a certain node of e-commerce, but is deeply integrated into the entire industrial chain. And this may be the new password for AI to activate the second spring of e-commerce.

Integration into the industrial chain: AI shows new magic

The high emphasis on AI is evident in the various performances of e-commerce platforms.

In a 20-minute speech at the 2023 Tmall Double Eleven conference, Dai Shan, CEO of Taotian Group, mentioned AI 20 times, "Taobao is a product of the last Internet technology revolution, and will also seize the next AI revolution." She said Taobao is gradually starting to test the waters of intelligence: "This year’s Double Eleven, we have prepared more than 10 AI tools for merchants to use."

JD.com also did not show weakness, and made the magic of AI stand out by equipping the entire line with intelligent customer service "Jing Xiaozhi". According to JD.com data, after 10 minutes of sale, JD.com cloud intelligent customer service has accumulated more than 1.88 million consulting services.

In addition, other Internet technology companies are also trying to get a share of the pie through AI. For example, Tencent Advertising uses the Huanyuan model to support intelligent advertising production; Baidu APP launches Baidu’s preferred intelligent assistant "Xiaoyou", which acts as an intelligent shopping assistant for consumers and provides "Double Eleven Calendar" presented on all major platforms; Xiaohongshu also announced an AI intelligent note assistant to help merchants achieve one-click release of product notes.

If you look at the role of AI in Double Eleven, it is throughout – integrated into the entire e-commerce industry chain, playing an important role at every node. This is mainly due to the development of AI models, allowing AIGC’s massive tools to present infinite possibilities.

AIGC tools represented by ChatGPT continue to break through in language understanding, text creation, picture recognition, creative painting, etc., which are highly compatible with the development elements of the e-commerce industry and can empower the industry at all stages. Specifically, AIGC can assume important responsibilities in product development, marketing, after-sales and other stages.

In the product development stage, AIGC can provide design inspiration, customize product descriptions and drawings according to requirements, and analyze factors such as product prices and target groups based on market information, and provide optimization suggestions and solutions.

In the product marketing stage, AIGC can help e-commerce companies reduce costs and increase efficiency in the production of marketing content, achieve accurate product recommendations, and promote innovation and upgrading in the form of live streaming.

In the after-sales stage of products, AIGC can assume customer service functions and can also be applied to order management links such as warehousing, delivery, and logistics to help e-commerce platforms further reduce costs and increase efficiency.

Overall, AI-based AIGC can achieve all-round coverage in e-commerce scenarios such as optimizing product selection decisions, intelligent customer service work, graphic material production, intelligent advertising, accurate associated recommendation, and processing image materials. Taking marketing as an example, AIGC can deeply tap the creative potential and generate multi-modal personalized social media marketing content such as text, pictures, and videos according to the platform, product characteristics, and target audience, saving creative time and creative costs, and improving the pertinence and attractiveness of marketing content.

It can be said that AI continues to empower in the field of e-commerce to reduce costs and increase efficiency, covering multiple application scenarios, which can basically run through every link of the e-commerce industry and bring further experience improvement.

AI deeply empowers and ignites the upward engine of e-commerce

The in-depth exploration of AI is the unremitting pursuit of e-commerce platforms and players.

As early as this year’s 618 period, e-commerce platforms and brands have used AI technology in the process of big promotion. For example, Taobao and Tmall launched the "AI Eco-Partner Program" to apply AI in store opening and decoration, product image creativity, marketing planning and promotion, content organization and creation, etc., to provide merchants with intelligent generative services in the fields of content, data and customer service.

From some achievements, nearly 500,000 merchants use Alimama AI video tools "mixed cut" and "painted cut" to send more than 2.50 million short videos; AI image-text tools "intelligent pictures" and "intelligent copy" to output nearly 10 million marketing graphics.

JD.com AI digital people help the transaction of goods, Client Server – JD.com Cloud launched the "Free Digital People Live Room Call" plan, and created "AI live streaming host" and "digital doppelganger" for some JD.com stores during the promotion period. According to JD.com’s battle report, during the 618 period of this year, the number of go LIVE merchants increased by more than 5 times compared with last year’s Double Eleven, helping to achieve a 246% increase in turnover compared with last year’s Double Eleven, and the cumulative consulting service volume of JD.com Cloud Yanxi intelligent customer service exceeded 700 million times.

It is worth noting that at the 2023 JD.com Global Science and Technology Explorer Conference and JD.com Cloud Summit "JD.com Technology Practice" sub-forum held on July 13 this year, the JD.com retail future brand AI RETAIL was also released. The main goal is to upgrade retail people, goods and markets based on JD.com’s AI technology capabilities. JD.com officially released a large-scale model with a parameter scale of 100 billion, focusing on retail, logistics and other industries.

At the 2023 Hangzhou Yunqi Conference held on October 31, Alibaba Cloud announced a full-stack upgrade of AI cloud computing, releasing Tongyi Qianwen 2.0 and 8 major industry models with a scale of 100 billion parameters. Many of Alibaba’s businesses are based on AI big model technology to innovate business scenarios and service models, and build future-oriented imagination.

The China Gold Research Report said that considering that the e-commerce scene is a key direction for AI to be implemented on the B-end, and Alibaba has the advantages of computing power, models, data and scenarios, it has strong confidence in the implementation of AI applications on Taobao and Tmall.

The e-commerce giant up the ante AI represented by Alibaba and Tmall is to value the strength of the latter’s deep empowerment and ignite its own upward engine. This is because AI can fully empower e-commerce and improve efficiency and quality significantly.

From the perspective of "people and freight yard", AI can empower e-commerce in all aspects, such as virtual live streaming hosting, intelligent product selection, virtual try-on, logistics performance, etc. From the perspective of e-commerce operation, AI can empower e-commerce in the full link, that is, from pre-sale product selection pricing, in-sale marketing recommendation, AI shopping guide, after-sales intelligent customer service, logistics performance, etc., to improve the quality and efficiency of the e-commerce industry.

This also means that AI is expected to improve the efficiency of e-commerce. It can optimize its conversion rate and repurchase rate while reducing costs, promote the quality and efficiency of the e-commerce industry, and make the industry develop steadily and healthily, or even achieve huge breakthroughs.

New inflection point! E-commerce will completely break through the shackles

Under the influence of AI, the e-commerce industry is approaching a new turning point and entering a new stage of development, which is expected to open up new growth space.

Without a doubt, the e-commerce industry will become an important showcase for AI in the future. With the continuous iteration of AI models, the technical reserves are more sufficient, and a variety of applications can be implemented, and the scenarios are richer.

From a technical point of view, taking ChatGPT as an example, it has launched multi-modal functions and introduced voice and image interaction capabilities. Taking ERNIE Bot as an example in China, it has been updated to version 4.0 after several rounds of iterations. According to Li Yanhong, the latest version 4.0 model is "comparable to GPT-4" in general capabilities.

From this perspective, the iterative upgrade of AI models can support the improvement of the actual effect of AI-related tools and applications, and naturally provide better performance and experience for the e-commerce industry.

Let’s take the C-end and B-end scenarios as examples to briefly list several practical cases where AI can help the e-commerce industry break free.

Facing the C-end, AI shopping guide and AI display content generation are particularly outstanding. Many overseas and domestic e-commerce platforms have launched AI shopping guide functions – understanding users’ vague needs through text interaction, and recommending specific products to them, ultimately improving the product turnover rate.

AI display content production is based on text comments, image effects, videos, 3D renderings, etc. to form a rich presentation effect, including AI try-on, AI home decoration renderings and other interesting and practical functions, with the ultimate goal of optimizing the shopping experience and improving the order conversion rate.

For the B-end, AI is mainly to improve the efficiency of marketing and store operations, and to reduce costs, improve quality and increase efficiency for sellers. For example, AI can easily realize online store management, providing sellers with intelligent product release and management, market analysis, customer reception, enterprise management and other functions, which is convenient for product management and customer management.

This year marks the 15th year of the 11th National Congress of the Communist Party of China, and the first Double Eleven of the first large-scale application of AI in the e-commerce industry. It is very certain that the powerful capabilities of AI will revolutionize the way consumers interact with e-commerce platforms, as well as the operating models of platforms and merchants.

And with this as a key development time node, with the strong support of AI, the e-commerce industry will be completely broken and reborn.

　　In the 1970s, the film Hai Xia, which was adapted from the novel Island Women’s Militia by writer Li Ruqing, was finally released nationwide after various twists and turns. The story of Hai Xia, the heroine of the film, and the island women militiamen spread all over the country overnight.The film "Hai Xia" created the artistic peak of China films at that time from the theme to the story, from photography to music. The "Hai Xia Spirit" of "loving the island for martial arts and inspiring dedication" shown in the film has also constantly inspired generations to forge ahead.

China Literature and Art: Salute to Classics

　　In 1975, Beijing Film Studio filmed the feature film Hai Xia, which was written by Xie Tieli, directed by Qianjiang, Chen Huaiai and Wang Haowei, and starring Wu Haiyan, Cai Ming, Zhang Liwei, Hong Xuemin, Chen Qiang, Yu Shaokang, Feng Enhe, Bao Gang and Chen Zhijian. Based on the fishermen’s life on Tongxin Island on the southeast coast in the early 1960s, the film shows the growth path of a group of female militia on the island, represented by the protagonist Hai Xia, as well as their fighting life of fishing and defending the country. The film highlights the characteristics of the hero’s clear love and hatred, strong will and clear mind. The film is a blend of stories, characters and island customs, with a fresh and simple style and delicate lyricism. In particular, the episode "Fisherman’s Girl by the Sea" in the film has become a long-lasting classic in the history of China movies.

▲ Military writer Li Yuqing

　　Wang Haowei, one of the co-directors of the film "Hai Xia", recalled in the program: "At that time, when I wanted to shoot this film, I went to the Nanjing Military Region with Xie Tieli and Qianjiang, and found Li Ruqing, the author of the novel" Island Women Militia "to discuss the script. At the same time, I also went to the southeast coastal areas to experience life. Our footprints were all over Jiangsu, Zhejiang and Fujian. We not only learned about the life of fishermen in the southeast coast, but also saw the prototype of Hai Xia — — Wang Yuexia. "

▲ Hai Xia prototype — — Wang Yuexia

　　Just when everything was ready to shoot, director Xie Tieli suddenly received the task of shooting other films, so the director group had to make other adjustments. Finally, it was decided that Qianjiang would be the chief director of the film, and Chen Huaiai and Wang Haowei would jointly direct it.

　　Vanguard militiawoman company of dongtou in Wenzhou, Zhejiang Province is a women’s militia company with a glorious history of 60 years. This women’s militia company was founded in the 1960s. Over the past 60 years, from taking up steel guns to defending their hometown to actively serving local construction, generations of Dongtou female militia have interpreted the "Hai Xia spirit" of "loving the island for martial arts and inspiring dedication" with practical actions, and their deeds have been written into the novel Island Female Militia. The prototype of Hai Xia, the protagonist in the movie Hai Xia, is the first company commander of this women’s militia company — — Wang Yuexia.

　　Nowadays, with the development of the times, the mission of female militia has a new connotation: not only to train and prepare for war, but also to serve local construction and participate in emergency rescue. Nowadays, urban buildings and activity venues named after "Hai Xia" can be seen everywhere in Dongtou. The volunteer organization named after "Mother Hai Xia" is also interpreting "loving the island and advocating martial arts, inspiring dedication" with practical actions.

　　At the scene of the program, Wang Jiajia, the sixth company commander of vanguard militiawoman company of dongtou, Yang Yanhui, the instructor, and Wang Yinyu, the volunteer representative of "Hai Xia Mom", talked about the inheritance of "Hai Xia Spirit" in Dongtou.

　　Talking about the selection of actors for Hai Xia, Director Wang Haowei said: "The selection of actors is very important for the creation of the film. At that time, there was only one shooting opportunity for a script. After shooting, I felt that the actors were not ideal and could not be replaced. If you change actors, you will suffer great losses in manpower, material resources and time. Adult actors were selected from Beijing Film Studio, Beijing People’s Art Theatre, China Youth Art Theatre, General Political Drama Troupe, Haizheng Cultural and Art Troupe, Henan Drama Troupe, Beijing Film Academy and many other art troupes, and invited these actors. "

　　It is even more difficult to choose a child actor for the film. At that time, children’s actors were cut off, and there was no ready-made candidate in the mind of director Wang Haowei. So the director group began to "look for a needle in a haystack" and went to various schools to comb their hair like a comb. This is how Cai Ming was "fished".

　　Ah Hong’s youngest son Asha was only in the first grade at that time. After class, he ran happily in the yard, made all kinds of faces, and his expression was very rich, so he was taken by the directors. The directors found many children who were suitable for Hai Xia, and dragged them all to the studio with jeeps, and asked director Xie Tieli to have a look. After director Xie Tieli made the final decision, these children entered the film industry.

　　At that time, Cai Ming, who was only 11 years old, was selected by the director to enter the cast of Hai Xia. As a child actor in the cast, Cai Ming bluntly said that she was very obedient, and the words, deeds and professionalism of the teachers in the cast had a subtle influence on her.

　　Talking about the professionalism of the teachers in the crew, Cai Ming said: "One day we were filming a scene on a reef, and when a dark cloud came up, we couldn’t shoot it. Everyone went to the distance to rest, the camera was in place, and the photographer Uncle Chengsheng Li sat next to the machine, and I sat next to him. At this time, a sea breeze suddenly blew, and the camera fell down. Everyone rushed over and found that the camera had fallen between Uncle Chengsheng Li’s shoulder and the reef. I don’t know how he passed so quickly. When Uncle Chensheng was lifted up, his back was bloody. From that moment on, I knew how a person should treat his work, which inspired me all my life. "

　　There is an island 8 nautical miles away from downtown Sanya, Hainan, which is a well-known tourist area in Hainan and an important outpost in the South China Sea. There has been a beautiful story of eight sisters guarding the world with one cavity and one blood.

　　The "West Island Women’s Militia Gun Squad" was founded in 1959, when their oldest was 19 years old and the youngest was 17 years old. At that time, it was the story of "eight sisters" who did not let their men "become famous" and won the first place in the competition field, which became a story in the country.

▲ The first generation of eight sisters artillery class

　　In the 1970s, the film Hai Xia, which was adapted from the novel Island Women’s Militia, became popular all over the country, and the "West Island Eight Sisters Artillery Squad" also became a heroic team of "Hai Xia" defending the island. With the passage of time, the "West Island Eight Sisters Artillery Squad" which has gone through more than 60 years has already become an established West Island Women’s Militia Company. The personnel are changing, but the "Hai Xia Spirit" and the unique fine tradition have not changed. Nowadays, women militia companies can be seen everywhere in the West Island. They inherit the "Hai Xia Spirit" with their youth and enthusiasm, and write the Tianya story of the new era.

Special feature of 1905 film network It’s May Day again. After the "strongest Spring Festival file" and "the strongest Qingming file" in history, this year’s May 1st file once again set a new box office record. According to the statistics of M Big Data of 1905 Movie Network, the box office of May 1st movie in 2021 has exceeded 1.67 billion by May 5th, an increase of 9.4% compared with the same period in 2019.

This year’s May 1st file is known as "the most crowded May 1st file". During a short five-day holiday, more than ten movies were arranged. And the types of movies cover almost all popular types, such as love, suspense, spy war, police and bandits. In this May Day film, the top three at the box office are,, and.

This year’s May 1st file handed in such a satisfactory report card. Zhang Jinfeng, the deputy editor-in-chief of China Film Newspaper invited by this issue, mentioned that the May 1st box office results are inseparable from these three effects.

Holiday effect

The publisher probably expected that more people would choose to walk into the cinema during this short holiday than when they were away from home!

@ Zhang Jinfeng: Especially after the epidemic, it has become a common phenomenon for the film market to choose holidays to enter the cinema in the process of recovery. Moreover, in the absence of imported blockbusters this year, the number of people watching movies has increased by 25.9%, which can explain the effect of holidays.

Head effect

The May 1st movie should be My Love and Above the Cliff. The box office of the two films has reached more than 60% of the total box office, which is a big cake at the box office of May 1st.

@ Zhang Jinfeng: My Love may still have a gap in the quality of creation, but this film wins by accurately grasping its mainstream audience — — Young female audience. And it still has comedy and touching plot settings, which has a good connection with the target audience of the film in terms of emotion.

@ Zhang Jinfeng: Speaking of Above the Cliff, all aspects of this film actually reflect a creative level of China-style films, which should be regarded as the first choice of the market audience.

Word of mouth effect

Although the pre-sale of My Love reached more than 74 million, it could not escape the ultimate judgment of film quality — — Word of mouth. My Love didn’t get a good reputation in the later word of mouth, and the Douban score was only 5.1.

In just five days, two films have achieved box office counterattack through good word of mouth.

Above the Cliff, the first runner-up, won a good reputation because of its solid output. The box office of the film Above the Cliff has been on the rise since May 1, and the cumulative box office has reached 627 million, surpassing My Love and ranking as the box office champion.

In addition, another film with a good reputation is "Decisive Fight Against the Black", which is more grounded. Many real cases are adapted to face the ills of corruption, and the interpretation of powerful actors such as,, and so on adds points to the film.

At present, although it didn’t get a box office jump in the initial stage, its high reputation contributed to the continuous benefit of the film, which jumped from the humble sixth place on the first day of release on May 1 to the third place at this week’s box office, with a cumulative box office of 146 million.

Many movies have seen the holiday effect of May 1st, thinking that getting together may be able to gamble on attention. Now, the May 1 ST file is over, and some people are happy and worried on the report card. It is true that intercepting the short-term box office cannot be used as a yardstick for judging a film, but the word-of-mouth gained in five days is enough to show the quality of the film.

After all, the success of the film is not limited to the box office.

Today’s film reviewDirector’s observation:The rare issue is not a summary program from the beginning to the end. The guests did not praise the "strongest May 1st file in history" in a routine way, but raised hidden dangers and problems under the high box office, and analyzed and discussed the phenomenon of excessive contrast between the previous holiday box office and the weekday box office. I hope that after reading it, I can have more understanding of the schedule arrangement of the current China film market, and I also hope that I can see high-quality domestic movies not only during the holidays, but also on weekdays. (Director of Ma Hongyu’s Today’s Film Review)

Some people may be surprised that what is the charm of football? It can be popular with so many people, regardless of race and social status. There is a shady venue, 22 people grabbing the ball and shooting under the supervision of the referee, and occasionally taking risks to send some balls to their own goals … In fact, for non-football professionals, the fantastic terms of skills and tactics are too empty. It must be admitted that the long game time of more than 90 minutes.

I think fans should be divided into several categories:

(1) professional fans. They are either professionals in the field of football or take the study of football as a profession. The biggest feature of these people is to start with the details and understand the truth inside the industry.

(2) Amateur fans. They just watch and talk about the ball as a hobby, and they have their own jobs in their daily lives. They may play a few wild games with three or two friends during the holidays, which is very informal. But they did enrich the population of football.

(3) fans who only watch the ball. As the name implies, people who never play football or rarely play football, who are skilled or unskilled in various professional terms in the field of football, and who like to play football games instead of actual football experience, are in a sense hidden football population.

(4) fake fans. On weekdays, they don’t pay attention to football news at all. They like to follow the tide of public opinion and firmly grasp the most critical core information. They have a keen eye and insight into the basic quality of human nature, and they can pretend to be top experts in the industry most of the time.

Four kinds of fans are four kinds of people’s attitudes towards football, so I want to extend this topic: On the first day of last year, the national football team was defeated by the Vietnamese team in the top 12 competition with a score of one to three.

The national football team lost to Vietnam 1-3 on the first day of the New Year’s Day.

An embarrassing result. Losing to such powerful teams as Japan and Saudi Arabia can only be said to be reasonable and lacking. However, the Vietnamese team had suffered a seven-game losing streak before meeting the national football team in the second round. People gave it the nickname 007. Is it unreasonable to be defeated by such a team? I don’t think the strength of the national football team will degenerate to be crushed by the Vietnamese team. I mean, the off-site factors account for a greater proportion of this loss, and a series of performances on the field are only results rather than reasons.

Is it really that important for a team with such a level of national football not to enter the World Cup? I don’t think it matters. For three reasons:

(1) Chinese people are not keen on football. Does anyone around you often play football? Will you support your children to play football instead of taking the entrance examination? Where does your child want to find a coach to play football? Is there enough football field near your home? It seems that there are many fans in China who care about the development of football. In fact, most of them are fake fans and fans who only watch football. There are not many fans who are really keen on football. So the level of the national team will not be much higher. With such a mass base, what kind of good seeds do you expect its national team to have?

(2) Lack of respect for the rules of football and sportsmanship. As we all know, in order to achieve the goal of marching into FIFA World Cup Qatar 2022 in 2022, the Chinese Football Association of zhong spared no expense in planning a group of foreign players. Trying to use the planning players to drive the overall strength of the whole team, but on the other hand ignoring the development of basic youth training, the domestic league stopped. Reality slapped them hard, and the national football team defeated Vietnam in advance. It is unwise to get quick success and instant benefit. The foundation is not firmly built, and everything else is just castles in the air.

One of the important reasons why Chinese people are not suitable for playing football is that they are not United enough.

(3) Chinese people’s thinking and physical conditions are not suitable for football. Chinese people pay attention to being unprofitable and can’t afford to get up early, but football happens to be a team sport, which needs cooperation to play the best effect, and being willing to be a green leaf means losing money, which is obviously not in the interest of individuals. In fact, we may find that China’s good sports, such as table tennis, badminton, gymnastics and diving, are often played by one or two people, and it is rare for more than three people to work together. Have you ever seen six people playing table tennis on a case in a formal competition? Even in table tennis, players may feel that another person is in the way. No way, this is a kind of thinking concept, and it is difficult for Chinese people to play team projects well. Then someone will ask why women’s volleyball and women’s football are better than men’s volleyball and men’s football. In fact, I don’t understand this either. Maybe it’s the difference between men’s and women’s thinking. It’s really strange that our female compatriots are more United than their male compatriots. As for the physical condition of Chinese people, it is enough to compare Koreans instead of whites and blacks.

To sum up, football is not the best choice for Chinese people, so it is not particularly strange to lose to a national team like Vietnam, which attaches importance to following the rules of football. But I saw the chilling side after this game. Wu Xi, the captain of the national football team, inadvertently dodged the ball and was associated with abalone advertisements. For more than ten years, he worked hard for the national team and set an example for players on and off the court. Because he was guided by public opinion, he was nailed to their so-called shame column, which was not only absurd, but also evil.

Let’s put ourselves in the shoes. Perhaps these players have a sacred love for football since childhood, or they have chosen to enter the field of professional football with the dream of making a fortune, and have a young meal. (Many people complain that football players have high salaries and low ability, but who will notice their life after retirement? Football is a young meal. If you don’t earn enough money when you are young, will you continue to play football to support your family when you are old? ) Crush competitors, step by step to the top of the pyramid of top clubs, and become a leader in the domestic field. Then, if you lose to a stronger opponent in international competitions, you will be scolded as having no fighting spirit. Are they really not spelling? Lei Wu got a leg cramp in the match against the Australian team. How many people really care?

The national football team in the top 12 relied on Lei Wu’s penalty to draw the Australian team.

Luo Guofu, the planning player with the lowest score in the audience, was boasted as a national hero by public opinion because he flew to block a cross ball. Is it absurd? Luo Guofu’s nickname is Yue Fei, and Li Tie’s nickname is Qin Gui … It’s a slippery record. Such a public opinion environment is really invisible. After that, foreign players in poor condition appeared in the team, so there was no starting position. I work hard in the team, but it is better for foreigners who have not come to the joint training for several months to have a high status. Whose mind will be balanced, and the players who plan on the court are in poor condition, shouldn’t local players follow suit? Anyway, there has been an unfair phenomenon. Let’s just lose to the Vietnamese team, and no one can think about it … Sadly, China Football.

We shouldn’t expect any good news from China football in a short time, because it is totally divorced from reality. In fact, the greatest charm of football is not the skills and tactics on the court, but the fighting spirit of people and the complicated world outside the court. Football is a sport, more like a war. In the final analysis, it is a complete summary of human struggle, including tactics, art, strategy, strategy, diplomacy, humanities, geography, chemistry, socialization and humanity. It is the biggest insult to football if you only pay attention to the goals on the court and don’t care about the culture and beliefs inside and outside the court.
