Crossing the high-end battle of life and death, Xiaomi now wants to fully embrace the big model.

Unexpectedly, in the future strategy, Xiaomi put AI in such an important position.

Last night, Lei Jun’s annual speech was a topic that everyone was discussing. Lei Jun, who had completed four years’ credits at Wu Da University in two years, released a series of products, such as a new generation of folding screen mobile phone MIX Fold3, Redmi K60 Extreme Edition, tablet 6 Max, mi band 8 Pro and so on, after talking about the story of how to choose courses, write programs and start a business.

In addition, he also shared the latest exploration of Xiaomi in cutting-edge technology, including hot areas such as large models and robots.

In the direction of quadruped robot, it seems that we haven’t seen such a level of innovation for a long time. At yesterday’s press conference, Xiaomi released the CyberDog 2 robot dog, which reached the level of "close to smart cars".

Two years ago, Xiaomi’s "iron egg" robot dog was welcomed as one more thing. What progress has been made in the second generation of iron eggs? Development engineers say that in short, it is "more dog-like".

First of all, it has a smaller size, close to the real small dog, weighing 8.9kg and being 36.7cm tall. CyberDog 2 is more bionic than the previous generation-it refers to the appearance and characteristics of organisms. Compared with the previous generation, CyberDog 2 has reduced its volume by 16% and its weight by nearly 40%. On the other hand, its price is higher than that of the previous generation: 12,999 yuan.

"It’s actually quite difficult to be a puppy. We have been working for more than two years," Lei Jun said. "The movement of robot dogs requires high servo motors, requiring small size, precise control, reaction speed and power. A dog needs 12 servo motors, reducers and corresponding electronic controls, and the products on the market are expensive. 」

Therefore, Xiaomi has developed a micro-motor system CyberGear, which weighs only 317 grams and has a maximum torque of 12N.m；: The control accuracy is 5, and the response time is as low as 20ms;

The new motor provides stronger dynamic response ability, supports richer movements and precise control. In addition, after 30,000 dogs’ parallel training on the reinforcement learning virtual environment platform, Iron Egg 2 can now fully maintain its balance, and it is not a problem to flip forward and backward and play skateboard, and its anti-impact ability has also been enhanced.

The upgrade is also reflected in the perception level. CyberDog 2 is equipped with 19 groups of sensor systems, including laser radar and touch sensors. The computing power of AI processor reaches 21TOPS, and it is connected to the AI voice interaction system of Xiaoai classmate, which makes it bionic and interactive. The experience has reached a new height. Xiaomi said that CyberDog 2 can achieve the ability of following and avoiding obstacles similar to drones.

Based on the successful experience of the first CyberDog, Xiaomi decided to continue to adhere to the open strategy, open the research and development technology of CyberDog 2 to the world, and encourage the participation of rice flour and technical geeks around the world. Lei Jun said that the open content includes the structural drawings, system codes and functional interfaces of robot dogs, as well as a set of visual programming tools.

In order to make people do DIY better, CyberDog 2 has designed nine detachable shells, all of which support 3D printing replacement. It even has an electrochromic special edition, which can change the skin color through programs.

When the CyberDog generation and the humanoid robot CyberOne were launched before, some people worried that Xiaomi’s research robot was just a "ticket-playing" nature and did not have the motivation for continuous research. But on CyberDog 2, we have seen a series of innovations oriented to basic technologies and applications, and more importantly, persistence.

Large language model is an important goal pursued by domestic and foreign technology companies. In this regard, Xiaomi said that as early as April this year, he set up his own Al model team, and the main breakthrough direction was lightweight local deployment.

A few days ago, Xiaomi’s 6.4 billion parameter model was exposed on GitHub, and it achieved the best performance of the same volume on both C-Eval and CMMLU benchmarks. According to the information given by C-Eval, MiLM-6B model has achieved high accuracy in all 20 subjects of STEM (science, technology, engineering and mathematics education), and many projects such as metrology, physics, chemistry and biology.

At yesterday’s press conference, Lei Jun said that MiLM-1.3B, the latest version of Xiaomi AI big model, has been successfully run locally on mobile phones, and some scenes can be compared with the running results of 6 billion parameter models in the cloud.

It can be seen that the research of Xiaomi’s big model focuses on landing and end-to-end operation. According to reports, their first deployment direction is the intelligent assistant Xiao Ai. Thanks to the large-scale model technology, Xiao Ai has a more powerful brain, which can answer questions, inspire inspiration, create art and play a role in natural dialogue. Combined with the dialogue characteristics of the big model, Xiao Ai’s interactive model has been upgraded, and its original ability has been combined with the powerful general ability of the big model.

At present, Xiao AI, a big model version of AI, has started the invitation test. The first batch of supported models include Xiaomi 12 series and Redmi K50 series. I wonder who is faster than HarmonyOS in landing the big model on MIUI?

In the face of fierce competition in the industry, Xiaomi chose a technological breakthrough. "We will always adhere to Xiaomi’s vision and values, make good products that touch people’s hearts and are kind in price, and continue to increase investment in research and development based on technology. Lei Jun said. He said that Xiaomi’s R&D investment in 2023 is expected to exceed 20 billion. At present, Xiaomi has laid out 12 technical fields and 99 subdivided tracks, and its technical investment will reach 100 billion yuan in the next five years.

Lei Jun said that Xiaomi will choose technical fields with long-term value to human civilization and continue to invest for a long time. In the process of exploring science and technology, we will follow the following principles: deep cultivation of the underlying technology, long-term continuous investment, deep integration of software and hardware, and comprehensive empowerment of AI.

In yesterday’s speech, Lei Jun introduced the course of Xiaomi’s mobile phone hitting the high end. From insisting on the high-end road, to building a technical system with deep integration of software and hardware, and constantly improving the user experience, we can see that today’s Xiaomi has set its sights longer.

　　CCTV News:From February 9 to February 25, 2018, the 23 rd Winter Olympic Games will be held inPyeongchang, KoreaHold.

　　From China’s first participation in the Winter Olympics in 1980 to the upcoming Winter Olympics in Pyeongchang, with a history of 38 years, China’s athletes have repeatedly attacked the gold medal, and every endeavor and harvest has written a legend of ice and snow.

　　In 1980, China first went to the Winter Olympics.

　　On November 26th, 1979, the International Olympic Committee (IOC) resumed the legal status of the Chinese Olympic Committee, which opened the door for China sports to go global in an all-round way. In the middle and late February, 1980, the China delegation participated in the 13th Winter Olympic Games held in Lake Placid, USA, which was the first time that China athletes set foot in the Winter Olympics.

　　In 1980, the China Olympic delegation entered the 13th Winter Olympics in Lake Placid, USA.

　　 Li Yan won the gold medal in the exhibition competition in 1988.

　　In the 1988 Winter Olympics in Calgary, China sent 13 athletes to participate. Like the previous two events, China’s athletes are still far away from the medals, and the official events are out of the top eight.

　　Li Yan’s old photos of the Winter Olympics 30 years ago.

　　However, it is worth mentioning that at that time, in the short track speed skating event of performance class, teenagers under the age of 20Li YanWinning 1 gold and 2 bronzes, such a good performance made the China delegation excited and full of confidence in the next Winter Olympics.

　　 In 1992, Ye Qiaobo achieved zero breakthrough in medals.

　　In the 1992 Winter Olympics in Albertville, China did not return empty-handed, and women’s speed skating and short track speed skating won three silver medals, ranking first in the medal list.

　　Among them, women speed skatersYe Qiaobo, won two silver medals in 500 meters and 1000 meters, ending the history of China Winter Olympics without medals. Li Yan also added a silver medal to China in the short track speed skating competition, which became an official event for the first time.

　　It’s a little pity that Ye Qiaobo had a chance to win the gold medal. Women’s speed skating 500 meters is the most sure event in Ye Qiaobo. In the competition, Ye Qiaobo could not fully accelerate because her opponent did not give way when entering the corner.

　　The opponent didn’t give way to Ye Qiaobo as required. Ye Qiaobo asked for a rematch, but the referee ignored it.

　　It was this accident that caused Ye Qiaobo to lose about 0.2 seconds, and finally came second, while her performance was only 0.18 seconds behind the champion.

　　Ye Qiaobo won the first medal in the history of China Winter Olympics.

　　Ye Qiaobo still cried after she walked off the podium. She felt wronged and was full of regrets for not winning the gold medal.

　　 In 1994, the gold medal dream of "Black Whistle" was shattered.

　　In February 1994, China sent 27 athletes to participate in the Winter Olympics in Lillehammer. China’s gold medal hopes are pinned on women’s short track speed skating. However, Chinese’s dream of winning the gold medal was blown out by the referee!

　　Short track speed skating women’s 500 m final, China’s top playerZhang YanmeiLeading all the way in the first three laps. Seeing that Zhang Yanmei was about to cross the line, an accident happened! Kathy, an American player in the second place, suddenly pushed and pulled Zhang Yanmei’s knee with her left hand, and squeezed it to the inside. This "out-of-disc move" made Zhang Yanmei almost fall and was forced to slow down. Kathy took the opportunity to overtake Zhang Yanmei and took the lead in crossing the finish line.

　　Zhang Yanmei

　　After Zhang Yanmei reached the finish line, he indicated to the referee that Kathy had committed a serious foul, but the Dutchman, who was in charge of the referee, ignored it. Players from many countries expressed their dissatisfaction with the unfair treatment suffered by Chinese, saying that the gold medal should be Zhang Yanmei. However, all this can’t impress the "judge".

　　In speed skating, Ye Qiaobo managed to win a bronze medal while dragging a broken leg. She hung her skates and returned triumphantly in a wheelchair, which became the sports myth of that year. Ye Qiaobo’s fighting spirit touched the people.

　　In addition, Chen Lu won the bronze medal in women’s single skating in figure skating, achieving a major breakthrough in China’s ice and snow sports.

　　1994 Lillehammer Winter Olympics Chen Lu

　　 In 1998, the gold rush failed

　　In the 18th Winter Olympics in Nagano, Japan, China sent a huge lineup of 60 people. However, it is a pity that the gold rush failed and won 6 silver medals and 2 bronze medals.

　　It’s a pity that there was a final in short track speed skating, and I missed the gold medal. Men’s 1000-meter final, China player after entering the half-way.Li JiajunRushed to the front, and he has maintained a leading position since then, but in the sprint, South Korean star Kim Dong-sung suddenly took a step when he was unprepared.Cross the finish line first with the advantage of a knife tipLi Jiajun missed the gold medal with great regret.

　　Li Jiajun finally only missed the distance of a knife tip.

　　Besides,Chen LuI won another bronze medal in the women’s single skating.Xu NannanChina made a breakthrough in snow sports by winning the silver medal in women’s freestyle skiing aerial skills.

　　At the Winter Olympics in Nagano, Chen Lu, who scored Butterfly Lovers, won the bronze medal again, and "Butterfly on the Ice" became famous internationally.

　　Xu Nan won a precious silver medal, which achieved a zero breakthrough in the snow events in China.

　　 In 2002, Yang Yang won the first gold medal in China Winter Olympics.

　　After repeated gold-rushing failures, the Olympic gold medal dream of China ice and snow athletes was finally realized at the 2002 Winter Olympics in Salt Lake City, USA! That winter Olympic Games, the famous short track speed skater.Yang yangOne person won two gold medals in a row, and the magical performance of this superstar made the dream of several generations of China ice and snow players come true.

　　In addition to the two gold medals contributed by Yang Yang, the China delegation also won 2 silvers and 4 bronzes in short track speed skating and figure skating, especiallyShen Xue/Zhao HongboWon the third place in pairs skating, which achieved a new breakthrough for China figure skating.

　　Shen Xue/Zhao Hongbo

　　In 2006, Han Xiaopeng was born.

　　The China delegation won 2 gold, 4 silver and 5 bronze in the 2006 Winter Olympics in Turin. Judging from the quality of medals, we are more proud than ever, and this pride comes from the "dark horse"Han Xiaopeng.

　　Han Xiaopeng, 22, won the gold medal in the freestyle skiing men’s aerial acrobatics competition with two perfect movements, which achieved a zero breakthrough in the men’s event in China and a zero breakthrough in the snow event in China at the Winter Olympics.

　　The performance of Chinese short track speed skating team in Turin Winter Olympics was not satisfactory. Under heavy pressure, several gold medals with high voices were missed. The only bright spot is the teenager.Wang MengThe outbreak. Wang Meng, 20, took the lead in the women’s 500-meter final and won the gold medal, shouldering the heavy responsibility of winning the gold medal.

　　Wang Meng

　　In the figure skating pair skating competition,Shen Xue/Zhao HongboThis is the biggest favourite to win the gold medal, but six months before the competition, Zhao Hongbo broke his Achilles tendon, so the possibility of participating in the competition is slim. However, Zhao Hongbo finally stood on the field. He not only completed the jump perfectly, but also won the bronze medal with Shen Xue.

　　It is also worth mentioning thatZhang Dan/Zhang Hao. When Zhang Dan fell heavily on the ice in the final, almost everyone thought that they would quit the competition. However, the strong Zhang Dan returned to the competition after a little treatment, and won the silver medal in the pair skating competition with Zhang Hao’s perfect performance. The prolonged applause from the audience was the best affirmation for them, which exceeded the significance of the medal.

　　Back in the game after Zhang Dan was injured.

　　After learning that she won the silver medal, the excited Zhang Hao hugged Zhang Dan.

　　 Women’s short track speed skating swept the gold medal in 2010

　　In the short track speed skating competition of Vancouver Winter Olympics in 2010, the China women’s team won all four gold medals and became the absolute overlord of women’s events, ending the Korean team’s dominance in two individual events.

　　500 meter raceWang MengStand out from the rest, and win the championship with the advantage that the opponent can’t match with its strong strength.

　　1500 metersZhou yangAlone, I faced three famous Korean players in the final. Strong ability in the second half and sprint helped Zhou Yang complete the almost impossible task, overtook the three South Korean generals, took the lead in crossing the finish line with absolute advantage, and ended the Korean team’s rule over the project.

　　The competition between China and South Korea in the 3000-meter relay is fierce. Although South Korea took the lead in crossing the finish line, it was cancelled due to a foul, and China won the first gold medal in the team event in the history of the Winter Olympics.

　　In the final 1000-meter race, Wang Meng and Zhou Yang joined hands to rush for gold. Although Zhou Yang withdrew from the competition early due to a foul, her continuous efforts also created conditions for Wang Meng to compete for the championship, and the latter achieved the "triple crown".

　　Shen Xue and Zhao Hongbo hit the gold medal of synchronized skating in the Winter Olympics for the fourth time. In the end, they succeeded, and they ended their careers with perfect performance.

　　Pang Qing and Tong Jian won the silver medal.

　　In the freestyle skiing women’s aerial skill competition, China’s athletesli ninaBefore the game, it was the biggest favorite to win the championship, but in the end it was a pity to win the second place.China women’s curling teamHistorically broke into the semi-finals of the Winter Olympics and won a precious bronze medal.

　　China women’s curling team

　　In 2014, China speed skating team achieved zero breakthrough in gold medal.

　　At the 2014 Winter Olympics in Sochi, China’s performance was not as good as that of four years ago, but it still won three gold medals, four silver medals and two bronze medals.

　　Among them,Zhang HongWon the women’s 1000-meter champion of speed skating, and achieved the breakthrough of zero gold medal in China speed skating in the Winter Olympics.

　　As a soldier, Zhang Hong saluted the national flag and accepted the review of the national anthem.

　　Jianrou Li

　　Once out of public viewZhou yangThe performance of "The Return of the King" successfully defended the women’s 1500m champion, which proved her unique talent in short track speed skating long-distance events.

　　It is worth mentioning that compared with the lack of grain four years ago, the China short track men’s team has made a big breakthrough: 19 years old.Wu Dajing500 meters to pick silver, 17 years oldhan tianyuPick silver at 1500 meters.

　　In addition, the China men’s curling team made history by advancing to the semi-finals in the Winter Olympics in Sochi. China Legion also achieved the best results in the history in men’s flower skating, snowboarding and U-shaped venues. Although the number of gold medals has decreased compared with the previous session, the structure of China’s ice and snow events has been optimized.

　　 Beijing’s bid for the Winter Olympics in 2015 was successful.

　　On July 31, 2015, at the 128th plenary session of the International Olympic Committee held in Kuala Lumpur, Malaysia, IOC President Bach announced:Beijing, China won the right to host the 24th Winter Olympic Games in 2022.Beijing will also be the first city to host both the Summer Olympics and the Winter Olympics.

　　On February 9, Pyeongchang, South Korea will open a contract of ice and snow.

　　With Beijing’s successful bid to host the 2022 Winter Olympics, this Winter Olympics in Pyeongchang has special significance for China.

　　I look forward to China’s athletes showing their charm in Pyeongchang’s Winter Olympic Games and making great achievements.

　　　　　　 The TV series "Wu Dong Gan Kun" won many fans’ expectations when it started shooting, and it has been publicized for a long time. The TV series "Wu Dong Gan Kun" starring Yang Yang [Weibo], Crystal, Chun Wu and Claudia [Weibo] will finally be registered on Oriental TV.

　　On July 30th, Li Hu, director Zhang Li, producer Zhang Wei, starring Yang Yang and Suo Xiaokun, the author of Wu Dong Gan Kun, appeared in Shanghai for the launch conference. When talking about shooting, Yang Yang said that although he was badly abused by "24-hour omnibearing", he still "played very enjoyable"; Talking about the subversion of this image, Yang Yang admits that he prefers challenging and lively characters and wants to break his cold image in the audience’s mind.

　　The slapping scene was "abused". Yang Yang claimed to want to break through the image

　　The TV series "Wu Dong Gan Kun" is adapted from Li Hu’s novel of the same name. It tells the story of an ordinary teenager, Lin Dong, who, after going through numerous difficulties and obstacles, gradually defeated the wicked and wicked, and finally turned into a heroic hero who saved the world and gained love and friendship.

　　At the press conference that day, a clip of Yang Yang’s slapping drama was broadcast, which attracted the attention of the media present. In the film, Yang Yang is wearing a heavy iron frame shirt, constantly running, falling and yelling in the mud; When shooting close-up, Yang Yang repeatedly held his breath in the water, truly reappearing the suffocating feeling of being pushed into the water. In this regard, Yang Yang said that when shooting the play, he was indeed "tortured", but this is not the reason why the actor "sells badly". "After all, this is what actors should do."

　　Compared with the previous role image of the cold male god, Lin Dong played by Yang Yang this time can be described as a very subversive image. Talking about whether he is worried that fans can’t accept such an image, Yang Yang admits that as an actor, he still prefers challenging, breakthrough and lively characters, and he also wants to break the cold image of himself in the audience’s mind.

　　When talking about the memorable scenes during filming, Yang Yang admitted that the night before filming the first scene of "Wu Dong Gan Kun", he was anxious to lose sleep, because he wanted to show his best side to the audience, but when he came to the set the next day and saw director Zhang Li, this tension disappeared without a trace. The director gave us enough trust to eliminate the tension. Yang Yang said that he would watch "Wu Dong Gan Kun" on time.

　　Zhang Li, the director of fantasy films, praised Yang Yang for his ambition.

　　Wu Dong Gan Kun is directed by Zhang Li, who is famous for his serious style and has directed historical and revolutionary dramas such as Ming Dynasty 1566, The Right Way on Earth is Vicissitudes, and Young Shuai. On the day of the press conference, Zhang Li responded to the outside world’s "questioning" about whether it was appropriate to guide Wu Dong Gan Kun earlier. "The concept conveyed by this work is very similar to my previous works. I like the temperament of this work after the second creation, and I also want to try some works of different styles. "

　　In addition to Zhang Li, the play also gathered artists from Yang Yang, Crystal, Chun Wu, Claudia and Ada [Weibo]. At the press conference that day, director Zhang Li also praised the performance of these actors in the play, saying that they were "greedy" for the camera. "They all have a kind of greed for the camera, and they seem to be tireless in front of the camera and repeatedly ask for’ one more time’. Impressively, once Crystal filmed the scene of hanging Weiya, until a little after midnight, she couldn’t stand still when she landed, and she still asked to do it again. "

　　At the press conference, director Zhang Li also praised Yang Yang’s performance in the play and thought that he "has the potential and ambition to become a good actor." Zhang Li said that after each shooting, Yang Yang would run to the monitor to look back.

CCTV News:Today (June 28th) morning, the major project of "Power Transmission from West to East" — — The first batch of units of Baihetan Hydropower Station in Jinsha River were officially put into operation for power generation.

Baihetan Hydropower Station has installed 16 hydro-generator units with a single unit capacity of 1 million kilowatts, which is the largest hydro-generator unit in the world at present, and the development difficulty is far greater than other units under construction and put into operation in the world, and it is known as the "Everest" in the world hydropower industry.

Lei Mingshan, Chairman of Party Secretary of Three Gorges Group:It is completely designed, developed and manufactured by China, so the successful production of the unit today has achieved a major breakthrough in China’s high-end equipment manufacturing. At present, China is not only the largest hydropower installation country in the world, but also the country with the largest hydropower construction scale and the fastest development speed in the world. China has become the innovation leader of hydropower in the world.

Baihetan Hydropower Station is located in ningnan county, Sichuan Province and Qiaojia County, Yunnan Province in the lower reaches of Jinsha River. It is the second stage of the four cascade hydropower stations in the lower reaches of Jinsha River, with a total installed capacity of 16 million kilowatts, ranking second in the world after the Three Gorges Project. The average power generation for many years is 62.443 billion kWh, and all units will be put into production in July 2022.

Everything seems to be a cottage. There is Huaqiang North in the mobile phone industry, and there is a high imitation Putian system in shoes, clothes and bags. Identifying genuine and fake cosmetics is also like playing the most difficult "finding differences".

But what many people don’t know is that the hospital that each of us will go to in this life may also have a cottage version.

In the past, there were about 2,000 "Concord Hospital" in China, but there were only three officially recognized orthodox Concord Hospital [1]. Walking into a "Union Medical College Hospital" casually is like a cat falling into Schrodinger’s box, and I don’t know whether the road ahead is dead or alive. What awaits me is Hua Tuo’s reincarnation or an undocumented quack.

When choosing a hospital, we should start with the name of this hospital.

The famous hospital you went to may be fake.

In Jin Yong’s martial arts Jianghu, there are "magical powers in ashes of time’s southern emperor and northern beggar", while in China’s medical field, there are "East Qilu, West Huaxi, South Xiangya, North Xiehe and Central Tongji".

However, the reputation of the hospital has also made some little-known small hospitals use their brains to "rub the heat" by the name of these well-known hospitals.

"tongji hospital" and "Union Medical College Hospital" once blossomed everywhere in China.In 2007, more than 50 hospitals across the country called themselves "Xiehe", and later this number increased to about 2,000 [1][2].

Therefore, in February, 2021, the State Administration of Market Supervision issued a document to check and clean up the private medical institutions that use well-known hospital names such as Concord, Huashan, Tongji, Huaxi, Xiangya, Qilu and Tongren [3].

Many "fake" hospitals named by the policy have been cancelled or renamed. Eye-to-eye survey shows that the fake "Union Hospital" in China has almost disappeared.Among the existing hospitals, 157 hospitals have changed their names from "Xiehe".Only one hospital in Xinjiang has "Concord" in its name.

At present, there are no private hospitals with "Huashan" and "Qilu" in their names. There are only two or three private hospitals with "Huaxi" and "Xiangya", while there are 89 private hospitals with "Tongren" and "Tongji".

However, some hospitals are still playing the edge ball tirelessly.For well-known hospitals such as Renji, Ruijin, Chang Gung and Zhongshan, which are not directly mentioned in the document, the number of impostors has increased instead of decreasing.

For example, among the existing hospitals, 31 used "Renji" as their former name, but 65 used it as their current name, which fully doubled.

There is also a hospital in Sichuan, which used to pretend to be "Xiehe", but now it is called "Chang Gung" with a registered capital of only 310,000, which may not even buy a medical device.

Geographically, the existing counterfeit hospitals are mainly distributed in Hubei, Jiangsu and Yunnan.

When these hospitals are named, they often deliberately impersonate well-known local hospitals.For example, there are several West China hospitals in Sichuan, and several tongji hospital in Wuhan.Many people who don’t know the truth may mistake these fake hospitals for "West China is divided into the West" and "Tongji is divided into economies".

Naming is just the beginning of fake hospital marketing.

In Hebei, the original Dingzhou Union Medical College Hospital, which has been cancelled, once posted a sign in the outpatient hall of the hospital claiming to be "National Union Medical College Brand Chain Hospital", and blatantly referred to itself and Peking Union Medical College Hospital as "Union Department", which is called "touching porcelain on the moon" [4].

In 2019, a pregnant woman went to the hospital for examination, and she was induced to have an operation in a daze. In the end, the cost of the operation was as high as 13,000, which was six times more expensive than that of ordinary public hospitals [1].

Peking Union Medical College Hospital had to emphasize many times.In China, only Union Medical College Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology, Union Medical College Hospital affiliated to Fujian Medical University and Peking Union Medical College Hospital are related [5].

Between the true and false Concorde, there is a galaxy missing.

Well-known hospitals are often impersonated, in the final analysis, because their medical level is generally recognized. Like Peking Union Medical College Hospital, which is often impersonated, it is almost an insurmountable "legend" in China Hospital.

According to the 2020 edition of China Hospital Rankings published by Fudan University,Peking Union Medical College Hospital ranks first among hospitals in China, and has been ranked first for many years.. Of the 48 departments in the hospital, 29 ranked among the top ten in China [6].

In addition, Peking Union Medical College Hospital is also good at solving all kinds of intractable diseases. According to the First List of Rare Diseases published in 2018, Peking Union Medical College Hospital basically has the ability to diagnose and treat 121 rare diseases included in the catalogue [7].

There are also two other hospitals belonging to the "Concord Department", which are also among the top 100 hospitals [6].

You know, National Health Commission’s data shows that there are more than 36,000 hospitals in China [8], and it is extremely difficult to achieve the achievement of ranking in the top 100 among so many hospitals.

Compared with the "fake Concord", the real Concord Hospital has never lacked patients, let alone used advertisements to promote itself. In 2020, Peking Union Medical College Hospital performed 36,697 operations, which is equivalent to more than 100 operations a day [9].

In addition to "Union Hospital", hospitals such as west china hospital and Huashan Hospital affiliated to Fudan University, which are often impersonated, are also in the forefront of the list of hospitals in China all the year round [6].

These hospitals often do not collapse in all subjects, and they can also have many special specialties.

For example,Huashan Hospital is not only good at dermatology and neurology, but also ranks first in infectious diseases in China [6].Shanghai Ruijin Hospital, on the other hand, is well-known in the world for its burn department. In 1958, it pioneered the successful treatment of large area burn patients in the world [10].

There is also the West China Stomatological Hospital of Sichuan University, which is famous for its stomatology. As the first stomatological hospital in China, it ranks first in the national stomatology rankings all the year round [11]. In 2020, the highest score of science in stomatology major of Sichuan University in the province reached 690, which was only four or five points lower than that in Qingbei [12].

Their strength is also largely attributed to the accumulation of history.The well-known hospital brand names alone have a lot to offer.

For example, Peking Union Medical College Hospital has been established for more than 100 years. Its predecessor was "Union Medical College" founded by British and American people in China in the Qing Dynasty. "Union" is a Chinese translation of "Union" [13].

Tongji hospital, formerly known as Shanghai Devon Medical College founded by German doctor paulun erich in 1907, was later renamed Tongji Devon Medical College, and "Tongji" means helping each other in the same boat [14].

After all, those fake hospitals can only copy their names, but they can’t copy their strength and history.

There are other naming routines instead of high imitation.

For ordinary private hospitals, the high imitation route is no longer easy to go, and there is no hundred years of history to fold their own buff. How should we choose the name of this hospital?

After analyzing nearly 30,000 private hospitals in Tianyan survey, we found that hospital naming actually has obvious preference just like naming newborns.People, health, safety, faith, love and beauty are the favorite words in the name of private hospitals.

After these keywords are arranged and combined, they all sound very sunny and positive.

Many hospitals have "Huimin", "Limin" and "for the people" in their names.Just like the "Zi Hao", "Zi Hao" and "Zi Hao" in the baby, it is as stupid and confusing. Hospitals in the name of "benevolence", "fraternity" and "friendship" are also spread all over the country, trying to convince patients of the humanistic care of hospitals.

Interestingly, just like the "Wanghao Milk" and "Haiyisi Shampoo" that can often be bought in rural shops,Many private hospitals are named "Harmony", "Harmony" and "Harmony", which is a high imitation of Union Hospital in disguise.

Once a "Union Hospital" in a certain place in Shandong Province, it is now called Union Hospital. There is also a hospital in Gansu that used the name of "Xiehe" for nearly 10 years, and now it is called Harmony Hospital.

In addition to take that positive sunshine route,There are also some hospitals that love to follow the "high-end trend" and name themselves "International", "Huaxia" and "Century". Some of these hospitals are really strong. For example, the scale of an international medical center in Shaanxi is comparable to that of a public third-class hospital, and the level of ear plastic surgery department is the world’s leading.

There are also some hospitals that will give themselves foreign names, such as Angel, Maria, Edward and Apollo, etc. If you explore carefully,You will find that many hospitals called "Maria" specialize in gynecology, while those called "Apollo" specialize in andrology.

It is worth mentioning that more than 80% of private hospitals are Putian hospitals [15]. According to China Youth Daily and other media reports, there are four families in Putian: Chen, Zhan, Lin and Huang.The names of hospitals under different families have their own characteristics [16][17].

For example, the Zhan family controls many "Maria maternity hospitals", the Lin family’s hospitals love to be named as "fraternity", "benevolence" and "Apollo", and the Chen family has many "Huaxia hospitals".

Although some of these Putian hospitals are famous for their beauty and high quality,However, there may be problems of incomplete qualifications and arbitrary charges.

Therefore, for a hospital, most of them do not have the so-called "hospital as its name suggests". Although there are conscience hospitals in private hospitals, they can’t be screened by name, not to mention some cottage hospitals that are keen on marketing. Trusting the name and advertisement of the hospital may become a "boy who sends money" to unscrupulous hospitals, and even end up making money and dying.

Choosing a hospital, doctors’ level, department qualifications and hospital scale can all be reasons, and the name is almost the least important factor.

The original title is "There were more than 2,000 Union Medical College hospitals in China, and only 3 were real".

　　CCTV News:The denuclearization negotiations between the DPRK and the United States have encountered bottlenecks. After being rejected by the DPRK for many times, the United States has repeatedly put forward requirements for declaring and handing over nuclear weapons, saying that the United States is "unwilling to wait too long." North Korea, on the other hand, advocates that without the measures to guarantee the system such as the Final War Declaration, it cannot abandon its nuclear program first.

　　According to Yonhap News Agency, Korean intelligence sources said that more than 10,000 troops can be identified at Merrill Lynch Airport near Kim Il Sung Square in Pyongyang, as well as equipment of ground troops such as artillery. Usually, when North Korea holds a military parade in Kim Il Sung Square, it will drill at Merrill Lynch Airport in advance. Therefore, the Korean military believes that North Korea is preparing for the military parade for the 70th anniversary of the founding of the People’s Republic of China on September 9.

　　The military of South Korea and the United States are stepping up surveillance and reconnaissance activities against North Korea, with the focus on whether intercontinental ballistic missiles will appear on the military parade. In the military parade in February this year, North Korea displayed the "Mars -15" which was considered as an intercontinental ballistic missile, which triggered regional tensions. In the sensitive period of denuclearization negotiations, this symbolic weapon has been paid special attention to. However, the Korean media reported that up to now, the South Korean military has not found intercontinental ballistic missiles, nor has it identified the shielding cloth used to hide missiles.

　　Professor Jin Dongye, Institute of Far East Studies, Han Guoqing South University: "North Korea has the strength not to succumb to the United States. In order to give greater significance to the 70 th anniversary of the founding of the People’s Republic of China, it may make a grand military parade."

　　U.S ambassador to the United Nations: sanctions against the DPRK will not be relaxed.

　　According to observers, hardliners in the United States are losing patience. On the 10th, Singapore’s Lianhe Zaobao website reported that US Ambassador to the United Nations Haley said, "They must understand that the international community still expects them to achieve denuclearization. If they want to delay, we are willing to wait, but we are not willing to wait too long." Haley further stressed that US Secretary of State Pompeo has put forward the "substantive" demands of the United States to North Korea, and Washington will not soften them or relax sanctions against Pyongyang.

　　Repeatedly saying that the US denuclearization plan is not North Korea’s "dish"?

　　What are the so-called "substantive" requirements? The website of Vaux magazine in the United States disclosed on the 8 th that the previously undisclosed timetable for North Korea’s nuclear abandonment proposed by the United States was as follows: North Korea handed over some nuclear warheads within six to eight months; The United States or a third country took over and removed the nuclear warhead from North Korea. However, it is not clear what concessions the United States is willing to make besides lifting sanctions or removing North Korea from the list of state sponsors of terrorism. According to two people familiar with the matter, this is the North Korean nuclear abandonment plan that Pompeo has repeatedly proposed to the DPRK in the past two months, but it has been repeatedly rejected. To make matters more complicated, how many nuclear bombs North Korea actually has has not been disclosed to the United States. Therefore, it is also difficult to verify the final situation of North Korea’s nuclear abandonment.

　　DPRK: The United States should respond positively to the DPRK’s efforts

　　Host of MBC TV station in Korea：“‘ Will not relax sanctions against the DPRK ’ Recently, hardliners in the United States have frequently made such remarks. North Korea strongly condemned this through a spokesman of the Ministry of Foreign Affairs. North Korea also said that even if it is not too late, the United States should respond to North Korea’s sincere efforts and urge President Trump to make a decision. "

　　North Korea’s Foreign Minister: North Korea should keep its nuclear knowledge.

　　According to Korean Central News Agency’s report on August 9, North Korea recently made a speech in the name of a spokesman for the Ministry of Foreign Affairs, saying that "some senior officials of the U.S. government are keen to stir up the turmoil of sanctions against North Korea against Trump’s will". The United States unilaterally adhered to "denuclearization first" and advocated international sanctions against the DPRK, which failed the expectations of the DPRK.

　　On the 10th, during his visit to Iran, North Korean Foreign Minister Li Yonghao said, "In order to abide by the agreement with the United States, North Korea agreed to denuclearize. But it is also clear that the United States will not give up its hostile policy toward North Korea, so North Korea should retain its nuclear knowledge. "

　　The DPRK urges relevant countries to sign the Final War Declaration.

　　Li Yonghao emphasized the DPRK’s position of agreeing to denuclearization. However, the DPRK’s insistence on denuclearization requires preconditions. Recently, the official newspaper of the Workers’ Party of Korea published a commentary entitled "Publishing the Final War Declaration is the primary task", saying: "Everything has a sequence to achieve its goals" and "The Final War Declaration will be an opportunity to transform the Armistice Agreement into a Peace Agreement." Since US Secretary of State Pompeo visited the DPRK at the beginning of last month, the DPRK has been urging relevant countries to sign the Final War Declaration.

　　Hong Min, researcher of Korea Unification Research Institute: "Why not even sign the Final War Declaration, which has become the basis of trust, but blindly and unilaterally ask for a timetable for denuclearization? (North Korea) basically means this."

　　Korean media believe that on the occasion of the 70th anniversary of the founding of the People’s Republic of China on September 9 and the coming of the Party’s founding day on October 10, the main goal in North Korea is still to pay close attention to the economy and hope to achieve economic results through denuclearization.

From the beginning of the development of the Internet, search technology has bloomed with amazing social and economic value. With the rapid development of information society, the data is exploding. Search technology meets the needs of information sharing and rapid retrieval through data collection and processing.

K-NN, Native Vector Search and Database in the Age of Big Model

With the emergence of recommendation, audio and video applications and the demand for large model scenes, it is imperative to introduce multimodal search to meet more complex search needs. On the basis of full-text retrieval, we increase the ability of vector search to analyze and retrieve unstructured data.

In the scene of vector search, the machine learning model is used to generate vectors to represent data objects (text, image, audio and video, etc.); Vector distance to represent the similarity between objects. The commonly used vector database uses ANN algorithm to complete the retrieval of massive vectors in a very short time.

K-NN can be used as a vector database. By introducing an advanced vector algorithm library to build a vector index, the constructed vector index will be persisted to disk, making the index more stable. Combined with the inverted index of ESCloud products, the capabilities of vector retrieval and full-text retrieval can be integrated to achieve a more powerful Hybrid Search capability. Based on the cluster of ESCloud, k-NN vector database can provide large-scale distributed capability and bring scalable vector search to users.

Scenario case

There are six main business scenarios based on k-NN, which are currently used in complex business scenarios in ByteDance:

·　Multi-modal search: including image search, semantic search, audio-video similarity retrieval, etc.

·　Intelligent recommendation: video recommendation, advertising recommendation, relationship recommendation, product recommendation, etc.

·　Intelligent question answering: FAQ based on Transformer, domain knowledge question answering based on LLM, and generative QA based on LangChain set;

·　Data de-duplication: video, audio and pictures are audited and de-duplicated, and the copyright of various materials is detected;

·　Safety risk control: fraud detection, black-out detection, risk assessment and anomaly detection;

·　Other applications: data mining, data analysis, search reordering, text search.

Take the copy similarity recognition scheme as an example.

In the scenario where users push the copy, in order to ensure the user experience, it is necessary to ensure that there will be no duplicate content in the pushed copy, so the similarity of each pushed content will be identified and duplicated. Each copy generates Embedding through BERT model, which is retrieved once in cloud search. If the similarity is lower than the threshold, it is judged as a new copy, which will be written into the k-NN vector database and gradually improved into a copy database; If the similarity is higher than the threshold, it is judged as a duplicate copy, and the push amount is reduced.

ESCloud, a cloud search service, is compatible with Elasticsearch, Kibana and other softwares and common open source plug-ins, and provides multi-conditional retrieval, statistics and reports of structured and unstructured texts, which can realize one-click deployment, flexible expansion and contraction, simplify operation and maintenance, and quickly build business capabilities such as log analysis and information retrieval analysis.
