AI doctor assisted diagnosis and accurate classification of sinusitis

Chronic sinusitis is a highly heterogeneous disease involving nasal cavity and sinus mucosa, and it is one of the most common chronic respiratory inflammatory diseases. The prevalence rate in China is about 8%, and 20% of patients are chronic sinusitis complicated with nasal polyps. In order to make the classification and treatment of nasal polyps more efficient and accurate, the research team of the Third Affiliated Hospital of Sun Yat-sen University developed the first artificial intelligence pathological diagnosis system for chronic sinusitis. It is reported that the "Single Vision Home Edition" of the system has passed the clinical test, reaching the level of a senior pathologist, and has been tested and used in a number of 3A hospitals with 5G network systems in Guangdong-Hong Kong-Macao Greater Bay Area.

Patients with nasal polyps need comprehensive treatment mainly by surgery, but the curative effect is not satisfactory at present, and the postoperative recurrence rate is high. The reason is that there are different subtypes of nasal polyps, and the treatment methods and prognosis of different subtypes of nasal polyps are very different. Therefore, accurate classification and individualized treatment of nasal polyps is one of the main ideas to break through the bottleneck of curative effect of nasal polyps. However, at present, the commonly used manual diagnosis method is to randomly select 10 visual fields of nasal polyps slides under a microscope and calculate the number of inflammatory cells in them, which has huge workload, low accuracy and impossible to calculate the whole film.

The Third Hospital of Sun Yat-sen, in conjunction with Tsinghua Pearl River Delta Research Institute and other hospitals and research institutes, has developed and iterated (at the cellular level, molecular level/full film and single vision) an artificial intelligence pathological diagnosis system for chronic sinusitis, developed a "full film platform version" and a "single vision family version" of AI doctors for different application scenarios, and built a cloud platform.

Among them, the "full-film platform version" of AI doctor is an artificial intelligence pathological diagnosis system for nasal polyps based on full-film, and related research results have been published in high-level journals such as JACI, eBioMedicine, a The Lancet sub-journal, and Chinese Journal of Otolaryngology and Head and Neck Surgery. The "Single Vision Home Edition" system has been developed and tested. The AI doctor "Sandy" can accurately identify the common inflammatory cells of chronic sinusitis and generate the first artificial intelligence pathological diagnosis report of chronic sinusitis. According to the standard of senior pathologists, its accuracy has exceeded 90%, which is helpful for accurate diagnosis of chronic sinusitis and subsequent individualized medication guidance.

It is conceivable that due to the huge potential demand in the fields of public welfare, public safety and national security, and the strong promotion of the rapid development of AI technology, in the near future, AI lip reading is expected to achieve rapid promotion and deep popularization, and the industrial prospects are very promising.

According to the continuous breakthrough of the bottleneck, it has become a reality that AI technology has achieved great success in the field of lip language recognition.

Many problems need to be broken.

However, Yan Huaizhi also said that at present, China’s artificial intelligence lip language recognition technology is still in its infancy, and there is still a long way to go if we want to use artificial intelligence to accurately recognize lip language.

From the perspective of language itself, human language has a high complexity. Of all the phonetic symbols involved in human speech, only about 30% are directly controlled by human lips, and 70% are teeth sounds, tongue sounds and throat sounds that are difficult to distinguish by naked eyes or even machine vision. Moreover, different people’s tone of voice, dialects, conjunctions, accents, and even beard cover will all lead to subtle changes in mouth shape, and it is this subtle change that will seriously affect the recognition and judgment of lip language by artificial intelligence.

From a technical point of view, the environment for artificial intelligence to collect lip language is usually complicated, and it is very difficult to accurately identify it. As far as the current artificial intelligence technology is concerned, the recognition level of long sentences and complex sentence patterns is not satisfactory, not to mention the problems of multi-scene recognition and lip recognition of multi-person images.

Yan Huaizhi said that only by solving the above problems can AI achieve a breakthrough in lip reading and move towards a mature stage of development.

There are many differences between different languages of human beings. Can AI read the lips of each language?

Yan Huaizhi introduced that most of the successful AI lip reading systems were limited to English models, because most AI models were trained based on English data. However, from the technical framework, the training models of different languages are basically the same, or they can be realized by the same kind of technical means.

Of course, in order to adapt to lip language recognition in different languages, some adaptive adjustments need to be made: on the one hand, data in corresponding languages should be selected for targeted training; On the other hand, the AI model needs to be adjusted, such as incorporating time masking, optimizing language model and improving superparameters.

In addition, the same language will have different mouths, even if the mouths are similar, they may represent completely different meanings. Therefore, a mature AI lip reading system needs a large number of lip feature sample data, and covers as many application scenarios and different types of speakers as possible, so as to improve the generalization ability of the trained lip recognition model and improve the recognition accuracy of AI lip reading for different mouth shapes and different ideographic languages.

Technical double-edged sword in urgent need of supervision

Despite all kinds of difficulties, more and more AI companies have begun to set foot in and plan to deepen the artificial intelligence lip recognition track. At present, the choices of major AI giants are different, which can be divided into lip language data, lip language video recognition, lip language understanding and so on.

Yan Huaizhi also said that at present, many artificial intelligence lip recognition technology fields have achieved initial breakthroughs, the prospect of full chain integration is expected, and industrial clusters are gradually taking shape.

From the perspective of application scenarios, AI lip reading has begun to emerge in the fields of social welfare and public safety. Judging from the current layout of the giants and the development trend of related technologies, AI lip reading is expected to have broad application prospects in identity recognition, national security, intelligent systems and so on. "It is conceivable that due to the huge potential demand in the fields of public welfare, public safety and national security, and the strong promotion of the rapid development of AI technology, in the near future, AI lip reading is expected to achieve rapid promotion and deep popularization, and the industrial prospects are very promising." Yan Huaizhi said.

Of course, technology application is a double-edged sword. Many people worry that lip-reading by AI will reveal the private content in people’s conversations, whether the parties are speaking publicly, whispering or talking to themselves. "Zhang Zhangkou" was stolen by others, and it was really terrible to think about it carefully.

Yan Huaizhi said that this kind of worry is not unfounded. On the one hand, the privacy leakage caused by AI lip reading may be caused by malicious lip reading, on the other hand, it may be the normal use of AI lip reading system, but the improper protection of storage and use leads to the theft or abuse of relevant data, which in turn causes damage to personal rights and interests. Moreover, because it involves the conversation content of the parties and has obvious directionality, this kind of privacy disclosure may be more harmful than ordinary personal information disclosure.

Therefore, Yan Huaizhi suggested that from the perspective of privacy protection, we should strengthen the formulation of relevant laws and regulations at the management level, strictly regulate and restrict the application scenarios, scope and purposes of AI lip reading, and increase the supervision and punishment of malicious use of technology. In addition, it is necessary to strengthen the construction of the security protection system of AI lip-reading system at the technical level, improve the recognition accuracy of the system by technical means, avoid technical abuse, and effectively ensure the content security of user conversations.

Liverpool 0-1 Bournemouth relegation team Salah missed the point and the whole team was in a downturn.

"I have always hated losing," Salah said in a conversation with Gerrard this week. "I don’t like losing."

Liverpool supporters traveled long distances to the south coast of England, only to see the performance of their team once again. After klopp’s team was defeated by Bournemouth, they would undoubtedly agree with the Egyptians.

When substitute jota’s header hit Smith’s arm, Liverpool got an excellent opportunity to change the result of the game. The referee awarded Liverpool a penalty through VAR replay.

Milner, so reliable on the court, only played a few minutes ago, and his cross created this penalty opportunity. However, Salah is Liverpool’s first player. However, his shot was far from the right post of the goal, which greatly reduced the possibility of Liverpool becoming the top four for the first time this season.

Salah’s performance before he missed the penalty was hard to convince. He kept losing the ball, made the wrong choice and was easily intercepted.

Think less than a week ago, the 30-year-old player surpassed Robbie Fowler in the 7-0 victory over Manchester United to become the player who scored the most goals in Liverpool’s Premier League history, and he was happy to tear off his jersey. How high-spirited he was at that time.

However, Salah was not the only Liverpool player with a low performance. After 20 minutes of hopeful opening, the performance of the whole team was disappointing.

In five Premier League away games against Nottingham Forest, brentford, Brighton, Wolves and Bournemouth, Liverpool conceded 11 goals and scored only one. The recent setbacks are becoming the norm on Liverpool’s way forward.

The gloomy expression on Liverpool players’ faces on their way back to the dressing room after the game reflects their mood. I wonder if they can improve before the second leg of the Champions League against Real Madrid on Wednesday.

Wuhan Evergrande! Wei Shihao Yan Dinghao and Li Yang joined the three towns, and the eight tigers of Evergrande will meet again to attack the AFC Champions League.

On March 11th, according to domestic media reports, Wei Shihao, Yan Dinghao and Li Yang, three generals of the Guangzhou team, joined the three towns of Wuhan, the new champion of the Super League. Because the Guangzhou team has been in arrears, all three players joined on a free transfer, and they went to Wuhan for the stable investment and the prospect of winning the championship. Today, the three towns in Wuhan already have eight old Evergrande generals, and they will be strong teams that cannot be ignored in the Super League and AFC Champions League in the new season.

On the afternoon of March 11th, according to Lu Mi, a reporter from Football News, three Chinese Super League champions, Wuhan Sanzhen, will sign Wei Shihao, Yan Dinghao and Li Yang.

Guangzhou team was relegated to 17th place last season. According to media reports, the team will operate at a low cost in the new season, and has been unpaid. The three towns in Wuhan continued to invest in the past two years, winning the Super League championship last season and winning the AFC Champions League ticket. In comparison, the three towns in Wuhan are the lofty branches that all players want to climb at present.

It is reported that the signing of three Evergrande players by the three towns in Wuhan has gone through a long negotiation, and it has also shown enough sincerity. Under the background of the sluggish overall football market, the stable investment of the three towns in Wuhan and their ability to play in the AFC Champions League are still very attractive to Evergrande players who once had a record of winning the championship.

According to Li Xuan, a reporter from Football News, the three towns in Wuhan didn’t hit a big contract. Stability, AFC Champions League and the pursuit of champions are the core competitiveness.

Feng Zhen, another football reporter, said that Wei Shihao and others were all free to join the three towns because of the team’s unpaid wages, so they didn’t pay a big price for the team. In addition, the Wuhan team’s move also released a signal to the outside world, not only to continue to compete for the championship in the Super League, but also to make a name for itself in the AFC Champions League.

After Wei Shihao, Yan Dinghao and Li Yang joined in, together with Gao Zhunyi, Liu Yiming, Deng Hanwen, Liu Dianzuo and He Chao, the three towns in Wuhan gathered eight great tigers of Evergrande, with young foreign aid and even a bit of a dynasty team.

In this regard, netizens have said, "I know, Wuhan Evergrande".

"Now, all the clubs that can pay wages normally are good clubs. If there is still the strength to compete for the championship, it is a perfect team."

"Half Evergrande last season, 80% Evergrande this season"

"It’s better than going to Shanghai. The three towns are basically the second team of Evergrande."

"Strengthen the three towns in Wuhan, and then it is ok to play the AFC Champions League."

"Goalkeeper: Liu Dianzuo defender: Deng Hanwen Li Yang Liu Yiming Gao Zhunyi midfielder: He Chao Yan Dinghao Wei Shihao is still three."

"What is the first definition of a top club? The boss has to have money! Don’t play football if you are poor! "

"Look at Wuhan’s investment, how long can it last?"

As a fan of Taishan Mountain in Shandong Province, I really appreciate the signing mode and efficiency of the Three Towns Club. Those sunspots don’t have to hack the Three Towns, and Evergrande players say that the Three Towns can play for a few years, regardless of how many years they can play.

Best team duel! The sun will make a smile and make a good job. ESPN is optimistic about the Warriors while ESPN!

On December 1st, Beijing time, the NBA regular season in the 2021-22 season was fighting. In a battle of focus today, the Sun will face the Warriors at home. Prior to this game, the Warriors 18 wins and 2 losses first ranked first in the league, and the Sun team ranked second in the league 17 wins and 3 losses. Therefore, this game was particularly attractive.

According to statistics, this is the first time that the NBA history has appeared more than 85%of the winning percentage, and it is in a team confrontation between the 7+ consecutive victory. The Warriors have achieved a 7 -game winning streak, and the Sun team has won the longest 16 -game winning streak this season. If the Suns can win again today, they will tie the team history of the longest consecutive victory.

Before the start of the game, the Suns officially released the preview map of the game, as well as warm -up maps such as Paul and other generals.

It can be seen that although this game can tie the long -winning record of the team history and whether they can defeat the Warriors’ top leagues, the Sun team will still be very relaxed. Paul, Booker, Claude and other people will laugh at the training ground.

The Warriors officially wrote: "The duel of the best record team of the two league, staged in Phoenix tonight!"

ESPN also debated this game. However, the result was one side, and everyone thought that the Warriors could win. Former NBA star Reydick said: "The warrior has a greater probability of winning the game, their defense is very good, they will take a lot of defense. The main tactics of the sun are to relieve it by the pick -and -roll, and then go to the ball three points. Unless Paul and the" Booker can play ultra -efficiency, otherwise it will be difficult for them to win. "

The reasons for the well-known commentator A-Smith is only one reason for the Warriors, that is Curry. He said: "I am not interested in this issue, because the Warriors will win the championship, and no one can defeat them. The Warriors will win bigger today, but the Sun team will win when they meet next time. Because they do not have Curry, Curry is the greatest shooter created by God. And the Warriors’ ball -free running and transfer balls are the top leagues. They are the purest basketball. "

Whether this game continues 17 consecutive victories, or the Warriors defend the league 1, we will know the answer in a few hours.
