　　Data Map: It is the graduation season for college students, and college graduates from Qingdao, Shandong Province are shooting personalized graduation photo on campus.

　　Reference News Network reported on June 11 that foreign media said that China is about to usher in the "graduation season" for students to graduate collectively. Graduates all want to keep good memories on campus in their own way. The "graduation economy" such as graduation dinners, travel and photo shoots has emerged from time to time and is very hot. Nearly 20% of graduates spend more than 10,000 yuan on graduation.

　　According to the China media report on the website of Lianhe Zaobao on June 8th, the hotels around the school will have a "harvest season" in the graduation season of college students every year, and most students choose the hotels around the school for graduation dinner. In order to attract graduates, some hotels also advertise that "every graduate can book a table with 8.8 discount, and drinks are free".

　　The owner of a restaurant near Northeast Petroleum University said that with the graduation season approaching, the peak of booking graduation dinner is coming. A coffee shop near Heilongjiang Bayi Agricultural University has held a graduation party with the theme of "First Love" since May 14th.

　　A graduate of Qingdao University said that since mid-May, he has had graduation dinners every night and spent a lot of money.

　　He said: "Usually, the living expenses for one month are around 1000 yuan. Now I have calculated in the graduation season, and 3,000 yuan may not be enough."

　　According to the report, in addition to graduation dinners, travel and photo shooting are also an indispensable part of graduates’ good memories in college.

　　Since the end of last month, all kinds of innovative graduation photos have been screened on various social platforms. In addition to the traditional graduation bachelor’s clothes, graduates can rent all kinds of clothes, and many people even seek the help of photography studios to shoot creative graduation photo.

　　A private photographer in Guangxi said that at present, the appointment for taking graduation photos has been arranged until the end of June, and people are still coming to consult, and the original fee has also increased from 100 yuan to 500 yuan.

　　Although Xiao Qin, a graduate of the School of Finance and Economics of Guangxi University, spent a month’s living expenses shooting graduation photos, she thought it was worth it. After all, "Youth never comes again. If you can, why not record your youth?"

　　According to a survey conducted by Qingdao Daily on 40 graduates from China Ocean University, China Shiyou University (East China) and Qingdao University, nearly 20% of the graduates will spend more than 10,000 yuan in graduation season, and most of them will be spent on graduation trips.

　　In addition, in order to impress the interviewer in the job interview, some students spend money to buy interview clothes. Xiao Chen, a graduate of China Ocean University, spent 2,000 yuan on brand suits and leather shoes, and spent a lot of time in making resumes, specifically looking for someone to design resume templates; He spent two or three hundred yuan on printing and copying his resume alone.

　　According to the report, Yuan Jinqiu, from the Department of Political Economy, School of Politics, Guangxi University, analyzed that the emergence of the "graduation economy" conforms to the laws of the market, and many businesses are ingenious in meeting the needs of graduates, which is a very positive economic situation.

　　However, since graduates are not yet financially independent, most of their expenses come from their parents. In this regard, Yuan Jinqiu believes that it is ok for graduates to participate in some job hunting and graduation commemoration activities if conditions permit, but it should be appropriate.

　　Wu Lianhai, consultant of the Mental Health Education and Counseling Center of China Ocean University, agrees with the above view. He said that college students’ consumption in graduation season is a way to express their classmates’ friendship, and some expenses are understandable, but the concept of face and conformity will inevitably contribute to the "graduation economy", so the expenditure in this respect must be measured.

On December 8th, the State Council Joint Prevention and Control Mechanism held a press conference to introduce the situation of further optimizing the implementation of epidemic prevention and control measures and answer media questions.

Graded and classified treatment

How do medical institutions do a good job in graded and classified treatment of key populations?

Guo Yanhong, director of the Medical Emergency Department of the National Health and Wellness Commission, said that in order to make overall plans for the layout and utilization of medical resources, the key point is to do a good job in the medical treatment and management of those who are seriously ill and have serious risk factors in COVID-19, and we have classified and treated those infected with COVID-19 virus.

First, for mild and asymptomatic infected people, those who have no basic diseases or whose basic diseases are in a stable period, they can take care of themselves at home.

Second, this part of patients with severe illness or serious risk should be admitted to designated hospitals. In order to ensure the treatment of this part of patients with severe illness or serious risk, we require that hospitals with strong comprehensive ability and high treatment level should be selected as designated treatment hospitals, and at the same time, they should be equipped with strong medical staff.

Thirdly, there are still some patients who have basic diseases or are mainly suffering from other diseases and go to general hospitals or specialized hospitals for treatment. In the process of treatment, they may be COVID-19-positive after testing. For these people, we have asked general hospitals and specialized hospitals to set up buffer zones, whether in outpatient, emergency or inpatient areas, so as to ensure that these patients can be treated and meet the needs of people’s medical services.

What kind of symptoms do you need to see a doctor in a medical institution?

Wang Guiqiang, director of infectious diseases department of Peking University First Hospital, said that if the following five situations occur, it is recommended to contact community doctors. If the illness is serious, you can contact 120 to go to the hospital for diagnosis and treatment.

The first situation is dyspnea or shortness of breath.

The second situation is that after drug treatment, you still have a fever. If it exceeds 38.5 degrees Celsius for more than 3 days, you should go to the hospital.

The third situation is that the original underlying diseases are obviously aggravated. For example, when the medication for hypertension is uncontrollable, the medication for diabetes is uncontrollable or there are other critical risks, you must go to the hospital for treatment in time.

The fourth situation is that children have some drowsiness, refusal to eat, diarrhea, vomiting, etc., which will not be relieved after treatment, and they will have to go to the hospital for treatment for more than two days.

The fifth is that pregnant women have headaches, dizziness, palpitation, shortness of breath or abnormal fetal movement, etc., and they should also go to the hospital for further diagnosis and treatment. Read the original > > >

nucleic acid testing

From what aspects has the scope and frequency of nucleic acid detection been reduced?

He Qinghua, a first-class inspector, said that further optimization measures require further optimization of nucleic acid detection, emphasizing that nucleic acid detection should focus on areas and personnel with high risk of infection, mainly reducing the scope and frequency of nucleic acid detection from the following aspects:

First, not to carry out all-staff nucleic acid testing according to administrative regions.

Second, except for special places such as nursing homes, welfare homes, medical institutions, child care institutions, primary and secondary schools, negative proof of nucleic acid testing is not required.

Third, cross-regional migrants will no longer be examined for negative nucleic acid test certificates or health codes, and landing inspections will no longer be carried out.

Fourth, according to the needs of epidemic prevention work, antigen testing can be carried out.

In addition, it is also required to carry out nucleic acid testing for employees in high-risk positions in accordance with the relevant provisions of Article 20 optimization measures, and the scope of nucleic acid testing shall not be expanded.

Employees in high-risk positions mainly include:

What are the special places that need to provide negative nucleic acid certificates and health codes?

He Qinghua, the first-class inspector of the Department of Transmission and Prevention of the National Bureau of Disease Control and Prevention, said that although the pathogenicity of the mutant strains in Omicron is obviously weakened, the risk of serious illness is higher for the elderly and key people with basic diseases, especially those who live in nursing homes and welfare homes, as well as places where special people are concentrated, such places are prone to cluster epidemics once the source of infection is introduced, so it is necessary to provide negative proof of nucleic acid testing for foreigners entering these special places. People who enter other general places, including those who take public transport and cross-regional migrants, do not need to provide negative proof of nucleic acid test, nor do they need to carry out landing inspection, but they should do personal protection, wear masks regularly, and reduce gathering and interpersonal contact. The new 10 measures also suggest that large enterprises and some specific places can determine some prevention and control measures by themselves, and all localities can take targeted measures according to the local epidemic situation. At the same time, it is mentioned in the 20 measures that "one enterprise, one policy" and "one park, one policy" can be adopted for the prevention and control of some key enterprises, and the new 10 measures are a further continuation and update of the 20 measures.

How often do employees in high-risk positions need to carry out nucleic acid testing?

Wang Liping, a researcher at the Center for Disease Control and Prevention of China, said that according to the ninth edition of the prevention and control plan and 20 optimization measures, the employees in high-risk positions are mainly divided into two categories:

The first category is extremely risky, which refers to the entry personnel, goods, people in direct contact with the environment, staff in centralized isolation places, medical staff in designated medical institutions and fever clinics in general medical institutions,They are required to conduct closed-loop management during the operation and conduct nucleic acid testing every day;

The second category refers to some employees who are closely related to residents’ lives, such as Shangchao, Express Delivery, Takeaway, etc., who have intensive working environment, frequent contacts and strong mobility. For such people, we should also do a good job in monitoring and nucleic acid testing.Nucleic acid testing is required twice a week.

home quarantine

What factors should people consider when choosing home isolation and centralized isolation?

Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, said that close contacts need some basic conditions to choose home isolation: it is best to have a separate room and good ventilation; If you share the bathroom, you should do a good disinfection treatment; If the family stays at home independently, they should be able to take care of themselves in life; People at home must stay indoors and refuse all kinds of visits. In this case, we still suggest that close contact with people can be isolated at home.

We emphasize that when we are isolated at home, if there are elderly people, infants and so on who need to be taken care of at home, then we should pay attention to personal protection to avoid potential transmission risks, and we should wear masks and do a good job of hand hygiene. At the same time, antigen testing should be carried out every day, and once it is positive, it should be reported in time. At the same time, do self-monitoring after being positive. When it is negative, you should also do a good job of daily self-symptom monitoring, including whether you have fever, cough and shortness of breath. If these manifestations appear, you should also report them to the community in time.

The elderly, pregnant women, infants and people suffering from basic diseases such as cardiovascular diseases must report to the community in time for special needs, including medication and treatment, when observing at home. In case of emergency, they should also seek medical treatment in time.

How to do personal protection for isolated people at home?

Wang Guiqiang, director of the Infectious Diseases Department of the First Hospital of Peking University, said that it is necessary to do a good job of personal protection for isolated people at home, and keep as little contact with family members as possible, and keep a certain distance if they contact. Include the following points that we emphasize:

First, the living room should be ventilated every day, and good ventilation is very important to reduce the spread of respiratory infectious diseases.

Second, the bathroom, bathroom, if it is best to use it alone, it should be disinfected every day. If it is shared, it must be staggered, and it should be disinfected well after use to avoid family transmission.

Third, do a good job in hand hygiene and environmental disinfection, including paying attention to hand hygiene during cooking and dining.

Fourth, when coughing or sneezing, be sure to cover it with a paper towel and throw it into the trash can to avoid the potential risk of aerosol transmission caused by splashing.

Fifth, used paper towels, masks, disposable gloves and other household garbage are put into plastic bags and placed in special trash cans.

Another thing we should pay attention to is that personal items should not be mixed and separated from family members as much as possible, because the items themselves may also pose the risk of virus transmission.

If the medical staff are infected with Covid-19, will they be treated at home or continue to work?

Guo Yanhong, director of the Medical Emergency Department of the National Health and Wellness Commission, said that medical staff is a very special group. Due to their special positions, they will receive a large number of patients every day, so they face the highest risk of infection and the work is very heavy. It can be said that occupational exposure is inevitable.Once medical personnel are infected with Covid-19, they should also follow the relevant requirements of the "New Ten Articles".However, in order to minimize the occupational exposure risk of medical staff, we put forward a series of requirements for the management of medical institutions.

Sealing and control measures

Units and buildings with "mixed pipe positive" detected no longer need to be sealed?

Wang Liping, a researcher at the Transmission and Prevention Department of China CDC, said that when the mixed tube is found to be positive, the relevant departments will inform the mixed inspection personnel as soon as possible, so that they can implement the local isolation measures, and at the same time, they will arrange personnel to take samples at home for review as soon as possible.Therefore, people in the same building and unit as those who are positive for mixed inspection do not need to be temporarily blocked.

When the recheck results are all negative, the mixed inspection personnel will immediately remove the isolation measures. However, if the door-to-door recheck results are positive, the control measures should be implemented in time, and the close contact should be controlled in time according to the results of field investigation and risk judgment, the risk area should be delineated, and the relevant epidemic situation should be handled well. Read the original > > >

Can only one positive infected person be detected without delineating high-risk areas?

Wang Liping, a researcher at the Center for Disease Control and Prevention of China,For the case that only one case is detectedIf the risk of communication in his work place, residence and activity place is relatively low, and after the secret connection is controlled in time, there is no risk of community communication after judgment, at this time, it is not necessary to delimit high-risk areas.

For a large number of households, a unit or a building may have hundreds of households.According to the current situation and risk judgment, according to the new ten articles, only the floors or households with high exposure risk can be judged to minimize the inconvenience caused by the epidemic to people’s lives.

After the high-risk area is demarcated, if no new infections are detected for five consecutive days, the seal can be released in time to avoid long-term seal control.. The new article 10 also mentioned that people with asymptomatic infection, mild illness or even close contact can choose home isolation. Therefore, it is very likely that there are some people in the community who are sealed off. For the newly infected people who are detected in the high-risk area after the risk area has been sealed off, if they live with the positive people who are strictly quarantined at home or are close to each other, there is no risk of community transmission outside the home after the judgment. In this case, even if they are positive, it will not affect the time to unseal the whole high-risk area, and they will still be unsealed without new ones for five consecutive days.

Vaccination for the elderly

Why do the elderly need vaccination?

Xia Gang, Director of the Department of Health and Immunization, said that the current epidemic situation is still severe and complicated, and vaccination still has good effects in preventing severe illness and death. Vulnerable people such as the elderly can easily develop into severe illness, critical illness and even death after being infected with Covid-19, and vaccination with COVID-19 vaccine will benefit the most. There are quite a few disabled and semi-disabled elderly people in China who live at home for a long time and rarely go out. However, they may still be infected during the company or visit of relatives, which may lead to illness or even serious illness and death. Therefore, it is still necessary to vaccinate.

According to Xia Gang, according to research, compared with young people, the risk of serious illness after COVID-19 infection is 5 times, 7 times and 9 times respectively, and the risk of death is 90 times, 220 times and 570 times respectively. If the elderly over 80 years old are not vaccinated with one dose, their risk of death is about 14.7%; If one dose of vaccine is inoculated, the risk of death will be reduced to 7.16%; If three doses of vaccine are inoculated, the risk of death will be reduced to 1.5%. Compared with no vaccination, the risk of death decreased by 9.3 times after vaccination with 3 doses. Read the original > > >

What services and conveniences will be provided for the elderly when they are vaccinated?

Xia Gang introduced that in view of the mobility of these elderly people, in order to enable them to vaccinate more conveniently, we have continued some previous good practices, including using mobile vaccination vehicles, opening special vaccination sessions for the elderly and opening green channels for vaccination for the elderly. At the same time, it is also suggested that all localities can send medical personnel with rich experience in diagnosis, treatment and vaccination to form vaccination teams, carry common equipment and medicines needed during observation after vaccination, and provide home vaccination services for disabled and semi-disabled elderly people, so that these elderly people can complete vaccination without leaving home.

CCTV News:Recently, the problem of sulfur dioxide exceeding the standard in Linfen City, Shanxi Province has aroused widespread concern. As a typical resource-based city in the north, the ambient air quality in Linfen City has turned sharply since the winter of 2016, and heavy smog weather has continued to appear. Up to now, Linfen City has experienced six heavy pollution weather processes, which lasted for 48 days and issued 13 heavy pollution weather warnings. On January 4, 2017, the air quality index (AQI) of monitoring points in Linfen City continued to rise, and the concentration of SO2 (sulfur dioxide) was as high as 1,300 μ g/m3, exceeding the national third-class standard ("minimum requirements for people to be exposed to acute health damage in the short and medium term") by more than 1,000, ranking first in 388 cities in China, 719 higher than the second.

On the 15th, Shanxi Provincial Environmental Protection Department announced that after three days’ investigation and analysis, the joint expert group of the Ministry of Environmental Protection and Shanxi Province has preliminarily identified five reasons for the excessive concentration of sulfur dioxide in Linfen:

First, coal consumption is large.From 2013 to 2016, the city’s coal consumption in Linfen increased from 30 million tons to 36.6 million tons, of which coking coal accounted for a high proportion, accounting for 65.3%, followed by power generation coal of 9.7 million tons, accounting for 26.5%.

Second, residents’ loose coal combustion emissions have aggravated sulfur dioxide pollution in winter.According to preliminary estimates, the annual sulfur dioxide emissions from coal-fired heating (except cogeneration) in six counties and cities (districts) along the Fenhe River in Linfen City are about 38,000 tons, accounting for 45% of the annual sulfur dioxide emissions. When winter enters the heating season, the proportion is even more prominent, accounting for about 70%. Among them, the emissions from heating boilers other than cogeneration account for 13% of the living sources.

Third, the promotion and use of clean coke did not achieve the expected results.Although clean coke is widely used in urban areas, due to its high burning point and difficulty in bank up, some people abandon the distributed clean coke, some mix clean coke with inferior coal, and a small number of clean coke fail to meet the sulfur index, and the amount of sulfur dioxide emitted by residents in urban areas and surrounding areas is still large.

Fourth, the transformation of coal-fired heating boilers and clean energy lags behind.At present, there are still 86 130-ton coal-fired boilers in urban areas, and there are basically no desulfurization measures. Although clean coke is used, the sulfur dioxide emission is still very large, which has a direct impact on the sulfur dioxide index in urban areas.

Fifth, there is no on-line monitoring for central heating in Dongcheng, the desulfurization device is ineffective, the factory area is messy and the management measures are not in place.(CCTV reporter Hu Xiaodong)

　 　 Special feature of 1905 film network In fact, the concept is not new, not to mention the amazing short film. In 2012, the animated film invited the protagonists of the game and turned it upside down. Up to now, Sony’s "Pixel Wars" has taken the road of combining real people with CG. Comedy stars such as adam sandler, kevin james and Josh Gad are invited. Obviously, the film didn’t want to be normalized from the beginning, and it was played in the guise of "war" and alien invasion, but it was still a shit and Loser transformation. It was not interesting or harmful.

　 　 At the beginning of the film, the film played a card of feelings and memories. Several strange-looking little boys, one of whom lost how to play the game, and the other, although brave, was defeated by others in the final championship battle. The other likes to chat with the girl in the game machine, full of small and medium-sized Xuan Xuan. Obviously, the film is paving the way, and it is also a common routine of Hollywood movies. Everyone’s adult life is greatly influenced by his childhood, so-called psychological trauma. So, the runner-up of the game, carrying the shadow of the second place, grew up to be an ordinary employee of a home appliance company, while the little fat man with no ambition and only catching dolls became the president of the United States. Yes, you are not mistaken. What is the screenwriter’s brain wide open for irony? Another "little devil" got into the panic, and the geek who is infatuated with beautiful women, as always, started a technical otaku.

　 　 When the scene jumps to the present, when adam sandler comes out, the whole style of painting is wrong, not to mention that kevin james has become the boss of the United States. From this time on, the tone of the film is slightly ironic and teasing. After watching such low-cost comedies in the United States, you will be quite familiar with and benefit from all kinds of jokes and techniques, such as ridiculing the American president to pieces and not knowing the "disaster". Isn’t it obvious that the president has no education? In addition, all kinds of important people in the White House have also become the object of ridicule, portrayed as a group of straw bags, officials are not like officials, and the general seems to be half buried in the ground. Of course, Americans haven’t forgotten to give a black hand to their good brother Britain again. The female prime minister has become thin and toothless, and looks like a menopausal woman with hormonal instability. She is not only pale but also very neurotic, which makes people think of her naked contempt for the Queen of England. Behind these satire and ridicule, what we can actually see is the characteristics of the film Pixel Wars, or the serious hooliganism as mentioned above.

　 　 Therefore, after adam sandler saw the heroine’s swaying posture, the first sentence she blurted out was "Wow", a heartfelt surprise brought out by hormones, and then the heroine happened to be in the emotional loss stage of life. Two people flirted and secretly fell in love, but they did not expect to start bickering because of a misunderstanding of a kiss, and they began to stage the plot of tell it to the judge. This way of communication between men and women is obviously the favorite of this kind of comedy, and they don’t like each other. Of course, adam sandler is not the only serious hooligan. Otaku still thinks about the dream girl in his game, and even draws many cartoons full of psychosexuality. One of the conditions for the little devil to join the team against alien aggression is to have dinner with tennis superstar Serena and spend the night together.

　 　 The more the film goes to the back, the stronger the desire of these men for women, and the creator has generously satisfied all their wishes. After becoming a salvation star, adam sandler won the beauty home, and the cartoon goddess of the otaku was regarded as a reward for the victory of the game, and became a real person, and Serena was waiting for the sandwich night that the little devil was thinking about … … It can be seen that these women were rewarded as trophies to these geeks, so when the beautiful game goddess in the movie dropped her double swords and leaned over to kiss the fat and filing otaku, the boys in the audience couldn’t help but make a sound with multiple meanings of regret, envy and jealousy.

　 　 It can be seen that "Pixel Wars" is like a beautiful world that a bunch of game geeks fantasize about themselves. In this world, not only can they become superheroes, but the opponents they beat are actually BOSS, who often can’t get through customs in the game, and then save the world. By the way, they also saved the setting that they have been a loser for the first half of their lives, and finally they can even win the beauty. Therefore, it is not surprising that the film is full of all kinds of imagination about beauty, hero and strength. After all, for the game otaku, the imagination of the external world is always better than the reality, otherwise Serena, a world champion who is strong and independent both physically and mentally, can’t throw herself at a cheating game champion.

　 　 It is precisely because of this that the audience of this "Pixel Wars" is estimated to be very limited. After all, the value position of such male chauvinism and taking all women as trophies is really out of line with the prevailing trend of feminism, not to mention that all the women in the movie are beautiful and amazing, while all the men seem to be a little diabetic.

"Pixel Wars" is such a typical American brainless comedy. The concept of pixels in the old-fashioned game of the film to create alien attacks is somewhat interesting in itself, but it is only limited to this. Wasted the setting and nostalgia that this attack method is electronic and gamified. On the one hand, the game characters in Pixel are much richer, and the story in the movie is still from a human perspective. On the other hand, they are all set as villains who will only destroy or even show their faces and break into slag, destroying their childhood and feelings in the game hall with steel.

This week, OPPO announced the latest technological progress in AI, performance, communication and privacy security, including the first handset/hands-free dual-mode satellite call for smart phones, the first 7 billion-parameter large model for end-side applications, the tidal architecture that debuted and many other cutting-edge technologies.

The brand-new technology portfolio announced this time will fully implement the next-generation flagship product Find X7 series, set a brand-new technical benchmark for the flagship mobile phone in 2024, and bring consumers an innovative flagship experience that refreshes standards.

Release handset/hands-free dual-mode satellite call, leading the evolution of satellite interphone to satellite mobile phone.

OPPO released the satellite antenna pattern control technology, which will realize the innovative experience of handset/hands-free dual-mode satellite call for the next generation flagship. This technology can dynamically adjust the radiation pattern of satellite antenna, make the antenna beam aim at the satellite dynamically, and ensure that users can keep connected and talk with the satellite in both handset and hands-free conversation postures.

Lu Bao, a terminal antenna expert in OPPO hardware engineering, said: "We are very happy to realize the latest breakthrough in satellite antenna technology in the next generation flagship product for the first time through continuous research and accumulation and using a series of innovative technologies and patents. Through satellite communication technology and fully upgraded antenna, smart communication and near-field communication technology, we expect users to get a reliable communication experience in the whole scene. "

The traditional satellite communication mobile phone adopts single antenna design, and it can’t meet the demand of transmitting power in the head-to-hand state. It can only support the use of hands-free mode, which will lead to problems such as unclear communication in harsh weather environment such as strong wind.

OPPO’s brand-new handset/handsfree dual-mode satellite call makes the mobile phone satellite call experience evolve from "satellite intercom mode" to "satellite phone mode" which accords with users’ intuition for the first time, helping users to obtain more efficient communication efficiency in extreme environments.

The industry’s first end-to-end application of the 7 billion parameter big model, the big model mobile phone entered the fast lane.

Facing the rapid development of large-scale model technology, OPPO officially launched the large-scale model of self-training in ODC — — After AndesGPT, it was also announced that the industry’s first 7 billion-parameter model of end-side application will be realized on Find X7 series.

Through the model compression such as high-precision 4-4bit quantization, the acceleration of reasoning engine and the hardware acceleration mode of deep cooperation with chip platform,For the first time, it brings a complete 7 billion-parameter large model to the mobile phone terminal, completely changing the way of using the mobile phone terminal AI.

Zhang Jun, general manager of OPPO Software Innovation Center, said: "OPPO’s self-trained and personalized big model — — AndesGPT contains many versions of parameters from one billion to one hundred billion, with abundant knowledge, infinite memory and good use of tools. The technical architecture of end-cloud collaboration can support diversified application scenarios.

With the cooperation of various technologies, we will also apply a large language model with 7 billion parameters and a generative visual model to the Find X7 series for the first time, which will bring a local AI experience with faster response, stronger processing ability and higher generation quality while ensuring the privacy and safety of users. "

Thanks to the complete ANDES GPT 7 billion-parameter large language model applied by end-side, Find X7 series will bring the next generation AI experience such as natural language understanding, text content summary and call voice summary.

Compared with other models on the same platform, oppoandesgpt 7 billion parameter large language model can bring 20 times faster response in the generation of 200-word prefix, and 2.5 times faster for the generation of 2000-word prefix.

At the same time, OPPO’s AndesGPT can achieve the maximum number of abstract words of 14,000, which is 3.5 times that of other models on the same platform. In terms of generation quality, compared with the 1 billion parameter model, the ANDES GPT 7 billion parameter large language model has a higher "IQ" understanding ability, which brings a more complete and accurate record to the call summarization ability.

OPPO also announced the AndesGPT generative visual model based on self-training, which will bring image semantic understanding, subject recognition and segmentation, image extension and generation capabilities to Find X7 series, and bring a new functional experience of subject elimination and real-life redrawing. AndesGPT’s generative visual mode brings a wider range of image experience to mobile phones.

Compared with other cloud models on the same platform, AndesGPT can only support human body recognition. ANDES GPT not only supports the recognition and segmentation of more than 120 kinds of subjects, but also can realize hair-level segmentation and multi-agent separation of up to six, as well as the filling and natural generation of super-large-area images, which greatly expands the application scope and practicability of the generative visual model.

In addition, the end-to-end application of AndesGPT generative visual model also brings 60% shorter generation time and higher generation accuracy compared with other models on the same platform, bringing users a more readily available generative visual experience.

Original tidal architecture, breaking through the bottleneck of chip energy efficiency

Facing the more stringent demand of flagship end users for chip energy efficiency, OPPO first announced the exclusive tidal architecture technology. As a technology stack of chip hardware and software integration, Tide Architecture has built a set of chip-level performance solutions from scene recognition, computing power demand, cache matching and computing power scheduling, which solves the problems of memory and computing separation and chip scheduling faced by mobile platforms and realizes the maximum energy efficiency performance of flagship chips.

Hong Hansheng, director of software technology planning and architecture design of OPPO, said: "Tidal architecture is a collection of chip soft and hard fusion technologies developed by OPPO, and it is a chip optimization technology created by a group of people who know chips.

In the past, from the first-level cache to the system cache has always been the technical area of chip design companies. Through the tidal architecture OPPO, it broke through the technical boundary and mastered the use of the third-level cache to the system cache. With the chip-level capabilities in no man’s land and deep water, it brought a great leap in computing efficiency to the flagship products. "

Through in-depth joint research and development with chip manufacturers, OPPO has penetrated the tidal architecture into the on-chip cache system that traditional mobile phone manufacturers can’t use finely, and jointly designed cache partition, dynamic ratio of CPU/GPU and fast channel scheme of clean data with chip manufacturers.

Through the tidal architecture, OPPO realizes the dynamic matching of system-level cache for the first time.Dynamically allocate system-level cache resources for CPU and GPU in real time according to computational tasks and rendering tasks. Through this unique technology, the tidal architecture can achieve an average energy efficiency gain of 8%.

In addition, the tidal architecture also supports a brand-new scene-level computing power and power consumption analysis model on the chip, which can realize the dynamic computing power and power consumption evaluation and analysis based on a single scene, and dynamically disassemble each computing task to the computing power distribution of each computing unit on the chip in real time, find out the best energy efficiency combination, and achieve more competitive energy efficiency performance for diverse user applications.

By accurately and dynamically scheduling the computing power of GPU, Tide Architecture can also control the display delay excellently, and realize an unprecedented continuous and smooth experience for Android flagship. In the test of simulating users to start applications 320 times a day, the standard deviation of Find X7 equipped with tidal architecture is only 11ms, which has achieved a more lasting and stable smooth performance than the same platform and other platforms.

Hong Hansheng also revealed that OPPO has begun to deeply participate in the design of the next generation of Tianqi chips and explore more possibilities of tidal architecture.

Super signal engineering, solving network problems in the whole scene

During the communication meeting, OPPO also announced a set of self-developed communication technology solutions — — Super signal engineering, through antenna technology, intelligent communication and near-field communication, enhances the full-scene communication experience of Find X7 series from outdoor to urban and from urban to indoor.

OPPO brings the highest performance four-antenna architecture to the next generation flagship product through antenna miniaturization technology and spatial distribution optimization of low-frequency four-antennas.
