Public welfare short film restores real Alzheimer’s disease　

Bo Huang recommended calling for watching movies.

The Father released a short public service announcement, and joined hands with Bo Huang, the manager of "Never Forget the Restaurant", to introduce the relevant contents about Alzheimer’s disease, which made the patients and caregivers of the disease enter the public’s field of vision. As an ambassador for film recommendation, Bo Huang appealed to the public to pay attention to the patients and caregivers of Alzheimer’s disease.

The film The Father tells the family ties and life problems between Anthony, the father and Anne, the daughter of patients with Alzheimer’s disease, and presents the disordered world in the brain of the elderly with Alzheimer’s disease with repeated and fragmented sensory narrative techniques, so that the audience can feel the helplessness and division of the elderly with Alzheimer’s disease from the first perspective.

The Father is about to be released, and Bo Huang, the ambassador of film public welfare recommendation, called on everyone to go into the cinema on the eve of Father’s Day and enjoy the wonderful performance of Oscar winner Anthony Hopkins on the big screen.

　

Oscar-winning masterpiece will be released soon.　　

The media in the industry highly recommend Father’s Day viewing as the first choice.

A few days ago, The Father held an advanced viewing in Beijing. Hundreds of fans, well-known media, film critics and industry experts enjoyed the Oscar-winning film in front of the big screen. Anthony Hopkins, who won the Oscar again after 30 years, was well received for his textbook performance in the film, and the audience called him "impeccable".

In addition, the unique narrative style of the film and the warm family story between father and daughter made the audience deeply shocked and burst into tears several times. The profound theme and humanistic care touched the hearts of countless audiences and aroused their love and yearning for their families. The audience felt that they should cherish this moment and not let time take away their love.

The film won numerous praises in the awards season, won 26 major awards in major film awards around the world, won 133 nominations, and won two major awards, namely, Best Actor Oscar and Best Adapted Screenplay. At the same time, the film won super-high scores on major websites at home and abroad, with the freshness of rotten tomatoes being 98%, the popcorn index being 91%, the MTC88 being 88, and the domestic douban being scored 8.7 by over 50,000 people.

Many media and film critics agree that the film The Father is the best film about the physical and psychological plight of the sick elderly in recent years. The media, industry experts and well-known film critics in the industry unanimously praised the film, praised the wonderful performances of the actors, and strongly recommended that "it must be the first choice for Father’s Day viewing", which was strongly expected by domestic audiences.

　　Recently, Shanghai Songjiang District People’s Court (hereinafter referred to as "Shanghai Songjiang Court") tried a criminal case of setting up a den in Dubai, United Arab Emirates, and committing telecommunication network fraud against domestic residents abroad in the name of stock innovation and recommending high-quality stocks.

　　On September 27th, Shanghai Songjiang Court issued a verdict according to law, and 21 defendants were sentenced to fixed-term imprisonment ranging from 7 years to 1 year and 6 months respectively, and fined.

　　Ms. Wang is usually keen on stock trading and has her own "circle of stock friends". Recently, someone introduced her to a so-called "God Man", calling herself "Someone" after adding WeChat, which can easily help her to make new shares and recommend high-quality stocks, and also let her join the group to share strong stocks, internal news of the organization, new strategies for private placement, watch the "internal" live broadcast room and listen to the investment "God" to explain stock knowledge. It can even "help you get an institutional seat account", and all this can be done through the platform you recommend.

　　Faced with the high-yield temptation of "new shares in the primary market" and "one-word board limit stocks", Ms. Wang was moved and rushed into the platform to open an account and transfer money to the private account designated by the other party to "buy stocks". So "the wheel of fate began to turn". At first, of course, it was a small profit, and it was normal to withdraw cash. When the investment increased to hundreds of thousands, not to mention withdrawing cash, Ms. Wang’s bank card was frozen. When she wanted to go to the group to ask questions, she found out that "you have been kicked out of the group chat" … …

　　Partial evidence of the case

　　Partial evidence of the case

　　What makes countless "Ms. Wang" step by step "remotely hooked" is a well-organized criminal gang with a clear division of labor. Since 2019, Hu Mou, Zhu Mou (both handled separately) and others have gone to Dubai, United Arab Emirates, set up dens to specialize in telecommunication network fraud crimes, and recruited so-called "lecturers" and "salesmen" from China until Dubai, and "China people cooperated to cheat China people".

　　The criminal gang adopts the corporate operation mode and is divided into different teams, and its salary income is calculated according to the "fraud KPI". There is a clear division of labor within the team, from the administrative supervisor to the lecturer and salesman. Through introductions or soliciting people, fraudsters are constantly coming here to join in the fraud to escape domestic legal punishment. These people have been engaged in fraud crimes in fraud dens in Dubai, United Arab Emirates for more than 30 days.

　　Criminal gang fraud steps

　　They have a highly targeted "financial" fraud model:

　　First of all, the real-name micro-signals purchased are "numbered" by a special person. The gang has a special WeChat group to contact WeChat "number merchants" and purchase a large number of "numbered" WeChat accounts through the "number merchants" for salesmen to chat with.

　　After getting the "cultivated" micro-signal, the drainage team left behind in China began to "powder", that is, the victim was "introduced" to the micro-signal of the salesman, and the salesman chatted with the victim according to the written speech and script and gained trust, so as to "fix the powder" next, that is, guide the victim to the webcast room to watch the lecturer’s lecture, and the so-called "lecturer" did not have the qualification to practice financial securities, or even basic financial knowledge.

　　Next, the lecturer will "drain" the victim to the platform made by the gang, such as Changsheng Capital, Ruida Assets and Huili Assets, by fictional plots with inside information and internal seats, and then seize the opportunity to make the victim unable to withdraw cash, but it becomes their "cash" moment. By the time of the incident, the gang had defrauded many victims, and the total amount of crimes was more than RMB 5 million.

　　Trial site

　　After the incident, 21 defendants were either arrested or surrendered themselves. After that, the People’s Procuratorate filed a public prosecution with Songjiang Court for 21 defendants suspected of fraud. During the trial, 21 defendants withdrew part of their illegal income.

　　After trial, Shanghai Songjiang Court held that eight defendants, including Wang, Fan and Lin, committed telecommunication network fraud against domestic residents abroad for the purpose of illegal possession, and the amount was extremely huge; Defendants Liang and Wu Moumou and other 13 defendants committed telecommunication network fraud against domestic residents abroad for the purpose of illegal possession, and the cumulative time of leaving the country for fraud dens within one year was more than 30 days, which belonged to other serious circumstances and should be investigated for criminal responsibility for fraud.

　　Twenty-one defendants who played a minor role in the joint crime and were identified as accomplices should all be given a lighter or mitigated punishment. All 21 defendants have confessed or surrendered, and they have withdrawn some illegal gains, and they can all be given a lighter punishment.

　　According to the facts, nature, plot and the degree of harm to society of each defendant, in order to protect citizens’ property safety, Songjiang court sentenced 21 defendants, including Wang, to commit fraud, and sentenced them to fixed-term imprisonment ranging from 7 years to 1 year and 6 months respectively, and fined them.

Recently, Yanjiang Branch of Ziyang City Public Security Bureau in Sichuan Province successfully destroyed a gang of "electric fraud outbound call service". By setting up VOIP (Voice Gateway) equipment, the gang disguised overseas fraudulent calls as domestic landline numbers, resulting in more than 10 people being defrauded of hundreds of thousands of yuan in just half a month. At present, Wei, who set up the equipment, has been sentenced to 2 years and 11 months in prison, and other people involved are still under investigation.

At the beginning of this year, the Yanjiang Branch of Ziyang Public Security Bureau found that Wei was suspected of building VOIP equipment to provide conditions for overseas fraudsters to cheat. In order to eradicate the "outbound" dens in time, Yanjiang police immediately organized a secret arrest operation and arrested Wei in the lobby of a hotel in Ziyang City. After the on-site trial, Wei confessed that the equipment set up in his hotel room was providing "electric fraud outbound" service for overseas fraudsters. After the search, the police seized four mobile phones, two VOIP devices and one laptop involved in the crime.

Further investigation by the police found that Wei and others not only set up equipment in Yanjiang District, ziyang, but also preset a number of VOIP equipment in Neijiang and other places, ready to provide a new round of "scam outbound" service for overseas fraudsters at any time. In a neighboring city and county in Ziyang, Wei has planned new dens in three towns and villages, with a full set of VOIP and supporting equipment, and even negotiated a commission of more than 800 yuan per hour with overseas electric fraud gangs.

"Once any new den is opened, thousands of fraudulent calls will be made intensively within a few hours, radiating more than 3 million people within the local area code, and the economic losses caused will be incalculable." Yu Yang, an anti-fraud policeman from Yanjiang Branch of Ziyang Public Security Bureau, said.

After seizing the hardware facilities, in order to prevent the resurgence of the gang, the police further pursued the organizational structure of the gang. In the following four months, the police handling the case went to many provinces and cities to collect and collect evidence, and accurately grasped the identity information of Wei’s family. After the gang’s organizational structure and criminal members surfaced one after another, in May this year, the police handling the case went to Fujian, Zhejiang and other places to collect the nets, and arrested the three main suspects involved in the case in one fell swoop, successfully cutting off more than 70 criminal chains of "electric fraud calling out black ash production", eliminating a large number of social hidden dangers.

At present, Wei, who set up VOIP equipment, was sentenced to 2 years and 11 months in prison by Yanjiang District People’s Court for fraud. Three suspects, including Que and Cao, have been criminally compulsory by the police according to law because of other illegal crimes. The case is under further investigation and processing.

In recent years, Bao Beier has gradually become a well-known name in the entertainment circle. Both his film and television works and his performance in the program have attracted the attention of the audience. Recently, he exposed himself as the "king of bad movies" in an interview, which triggered a heated discussion among many netizens. Is this a helpless self-mockery or a compromise to reality? Let’s discuss this topic together.

Bao Beier’s development experience in the entertainment circle can be said to be ups and downs. He once became famous overnight because he played a funny role in the movie "Never Imagine", and many subsequent works were often criticized for their weak plots and rough production, although the topics were constant. In this interview, Bao Beier admitted that he was the "king of bad movies", which made people think that some films he participated in in in recent years were really lacking in quality, as he said.

When it comes to "bad movies", many people may think of some movies with rough production and poor story lines. In the eyes of many viewers, bad movies are not only synonymous with low cost, but also a denial of the creative team. However, behind Bao Beier’s "bad film" may be his helplessness as an actor and his compromise for survival. The competition in the film and television industry is fierce, and actors often need to choose their works in a short time, instead of always acting in high-quality films as they wish.

This phenomenon is not uncommon in China’s entertainment circle, and many powerful actors are under pressure to choose their works. Some actors are willing to try all kinds of roles for the sustainable development of their careers, even some "bad movies" in the audience’s mouth. Bao Beier’s self-exposure of helplessness may reflect the unknown hardships behind many actors. They may not want to admit it, but in this fast-paced industry, compromise is the norm. Especially for Bao Beier, he needs to find a balance between keeping his artistic pursuit and pursuing market demand.

Some netizens’ comments on this phenomenon can be described as varied. Some people sympathize with Bao Beier’s experience and think that he is not a "bad film king"; Others think that actors should take responsibility for these works if they choose them themselves. In the final analysis, it is worth our reflection whether the screenwriter and director have poor control over the script or the actor’s own choice.

In the interview, Bao Beier also mentioned some experiences of learning from excellent directors and screenwriters, which showed his pursuit of his career development and his love for art, but it also made people curious about his future choices. Will he reject "bad movies" and choose a more in-depth and challenging role? Or after all this, continue to struggle in mediocrity?

In fact, on the huge stage of entertainment circle, the fate of many actors seems to be inseparable from the quality of their works, and Bao Beier’s experience is the epitome of it. Although he exposes himself as the "king of bad movies", the audience also hopes that he can choose more works that fit his acting skills in his future work, so as to better show his talents.

Of course, Bao Beier’s frankness and humor also let us see the real him, who is no longer just an actor on the big screen, but an ordinary person who is trying to make a breakthrough in the entertainment circle. His experience makes people think, how did today’s "bad film" come into being? Is it also related to the change of market environment and audience taste?

In such a commercial environment, how to maintain the quality of creation has become a test for all film and television people. With the development of the industry, more and more actors try to use technology and intelligent tools to help their own creation and improve the quality of their works. In particular, the rapid development of AI technology has brought different possibilities for creation. Just like with tools like Sohu Simple AI in content production, actors and creators can better create and design around market demand.

In any case, behind Bao Beier’s self-mockery of the "king of bad movies", what he reveals is his true feelings about his career and uncertainty about the future. In this ever-changing entertainment circle, what the audience expects to see is not only the constant efforts of the actors to improve the quality of their works, but also the endless creative enthusiasm.

Editor in charge:

Tank 300 2024 is officially launched, and the new model has three options, which can be divided into two series according to the engine type. E20CB 2.0T, 199,800, 216,800 E20NA 2.0T, 226,800

E20CB engine is a high-power version of 4C20B developed by Great Wall Motor. The standard is 167 kW/387 N m, and the parameters are the same as the old one. Therefore, there is nothing worth reading about these two versions in theory, but I still want to talk about them, because the names of these two versions are Challenger and Conqueror respectively, while the guide prices of the old challenger and Conqueror using the same engine are 198,800 and 215,800 respectively, and the new price has improved 1000 yuan.

If the price is raised by 1000, the engine and gearbox will remain unchanged, and the configuration must be changed.

The change is that the new model has more "anti-rollover system", the window is upgraded from the main driver’s seat to the whole car with one button, and the wireless charging function of the front mobile phone and the ETC device of the original car are added.

The value of these configurations is more than 1000 yuan, and only one anti-rollover system has this value.

So what’s the difference between the 226,800 new Crossover version?

The old version does not have the option of the traveler version, which is a new version; The engine used in this version is also brand-new, with a power reserve of 185 kW/380 N m, and the torque is 7 Nm lower than that of the old one, but the power is increased by 13 kW, and the power is increased. And the fuel consumption is also reduced, the fuel consumption of E20CB version is 9.9L, and that of E20NA version is 9.81L；; The technology to reduce fuel consumption is the light mixing system. Refer to the figure below, which is the structure of the light mixing system on the vertical platform.

The so-called light mixing system is to integrate a "BSG motor" (all-in-one machine for power generation and starting) into the engine, whose power is generally less than 10 kW, and the capacity of the power battery pack is only about 1kWh; Low-power motor and low-capacity battery pack determine that BSG motor can’t assist in full-time output. Light-mixing system mainly assists in outputting power during vehicle starting and acceleration, and the output part is the part that the engine can reduce, so the fuel consumption is reduced.

However, the fuel saving effect of light mixing system is very limited, which can be reduced by 5% at best.

However, compared with the fuel car, it is better than nothing, and the power of E20NA engine is sometimes improved, so it is reasonable to define the Crossover version as the flagship version. However, it should be noted that there is no differential lock in this version, and there is no option to provide optional equipment from the configuration list. The off-road vehicle without differential lock … This version is actually the old "city version", which adopts a timely four-wheel drive system, similar to herdsman Sahara, and has little practical significance.

E20CB Challenger version has rear axle differential lock, supports front axle differential lock option, and uses part-time 4wd.

E20CB Conqueror version has front and rear axle differential locks, which will have a strong off-road capability with part-time 4wd system.

To sum up, the off-road version of the new tank 300 still depends on the conqueror version. Although the price of the challenger version is 17,000 yuan lower, it is not recommended to choose it, because it will cost 6,000 yuan to install the front axle differential lock! The configuration of the two cars is also very different, such as front and rear air curtains, steering wheel heating, 220V power supply, leather seats, front seat ventilation and Yanfei Lishi speakers. The value of these configurations far exceeds 17,000 yuan, so the most worthy version of the new model is the conqueror version.

It is not recommended to choose a light-mixed version with a brand-new engine. After all, tank 300 is chosen for off-road, and off-road vehicles without differential locks are soulless.

Suggestion:

Great Wall Motor should speed up the launch of the 300 PHEV version of the tank, and the two hybrid technologies of light mixing and oil-electricity mixing should be eliminated! Take the tank 500 Hi4-T as an example. This car is a plug-in hybrid car, and its pure electric mode can travel over 100 kilometers, so it is not necessary to burn oil when using the car at ordinary times. The cost of charging is only equivalent to the fuel cost of 1~2 liters per 100 kilometers, while the real fuel consumption of the light hybrid tank 300 will be about 11L/100km on average, and the difference in vehicle cost is too great.

Therefore, the sales volume of the tank 500 Hi4-T in the first month of listing far exceeds that of the fuel version of the tank 500, and the users of the tank 300 are more concerned about the cost of using the car. At this time, it will be insincere to take out a lightly mixed tank 300.

Tank 300 Hi4-T is coming, so it is suggested that this version introduce three options. 226,800 yuan, rear axle differential lock 239,800 yuan, front and rear axle differential lock 259,800 yuan, urban version, differential lock optional, equipped with L2-class auxiliary driving system.

All versions provide 2~3 modification schemes, and the limited edition of the official reform will be launched after the first quarter of the plug-in version, and the price will be set at around 280,000-330,000; Starting from the fourth quarter, the tank car should build a brand-new brand image and concept with the tank 300/500 Hi4-T, and drive into the green mountain Yuan Ye with the green number plate.

Recently, Harvard University announced that starting from the fall semester, the self-developed language model CS50 Bot will be used as the teaching assistant of the popular course Introduction to Computer Science, so the new students will become the "first batch to eat crabs". This move has caused heated discussion on the Internet, and some people worry that AI will undermine students’ motivation to learn; Professor Harvard said that AI teaching assistants can alleviate the real teaching dilemma and improve the learning experience.

Wen, Luna, Jennifer

Since last year, the popularity of the AI topic has not diminished. However, it is still surprising to see that Harvard will "hire" AI in the ace elective course: "Has the application of AI evolved so fast?"

The news came from Harvard Crimson. David Malan, the lecturer of CS50 (Introduction to Computer Science), confirmed that this course will start from the autumn semester, and AI will serve students with 50 Course Assistant and Teaching Fellow (TF is a more advanced teaching assistant than CA).

The headline of Harvard Crimson &Malan’s Twitter response

The AI used this time is not the familiar GPT-3.5 or GPT-4, but a language model CS50 Bot developed by Harvard itself. It will be responsible for answering some common questions in the course, giving suggestions for revising students’ homework, and answering students’ questions at any time outside the working hours of other teaching assistants.

The CS50 course, in which AI is a teaching assistant, is a popular course at Harvard. In the past decade, the number of students enrolled in the course ranges from 500 to 800 each year. There are even students from other majors who have switched to computer science or engaged in related work in this major after finishing classes.

CS50 Statistics on the number of students who choose courses every year

Such a popular course, when Harvard has not launched a complete educational application scheme for AI, directly introduces AI teaching assistants, which makes people sigh, "How dare Harvard!"

The hot discussion on the Internet also has different ideas:

Some people think that the function of AI is too powerful, and worry that this is the beginning of AI replacing human beings?

Some people also question the ability of AI, and ask Harvard that the annual tuition fee is as high as $50,000. Is it fooling students with AI?

Some people also worry that AI will make students no longer motivated to learn, and even completely subvert human cognitive development.

So, as one of the representatives of the top universities in the United States, what does Harvard applied AI assistant think? What kind of thinking does Harvard have in the face of all kinds of doubts about the AI crisis?

Harvard’s hottest CS50 also has bad reviews.

AI teaching assistants are here to "put out the fire"

Will AI replace human teachers? This is the first reaction of many people after seeing Harvard news.

However, if you look through the report in Harvard Crimson, you will find that CS50 Bot, the teaching assistant, is more like "fighting fire" than replacing human teaching assistants and professors.

On the one hand, Malan, the lecturer, has always positioned CS50 Bot as a learning tool for students, and never mentioned that Bot should be the lecturer. Even as a teaching assistant, Bot is "inferior", and its advice can only be considered "accurate" after being confirmed by other teaching assistants.

On the other hand, Malan urgently hopes that AI can improve students’ learning experience, so that this big class of nearly 1,000 students can also provide 24-hour one-on-one tutoring. In the past, this was an impossible task.

Professor Malan gave a lecture on Introduction to Computer Science.

Malan is not only planning a large-scale AI test, but also considering the dilemma of real teaching.

In many people’s impression, Harvard’s ace course has its own aura-in the YouTube recording of CS50, David Malan stood on the spacious stage of Sanders Theatre and explained those complex computer concepts like a drama.

If you are lucky enough to study at Harvard, you will also know that this course also has a huge teaching assistant group to provide reference materials and homework guidance for students.

But in March this year, another report in Harvard Crimson, Undervalued, but Highly Utilized, revealed the bitterness behind the brilliance of these large-scale introductory courses.

The Harvard Crimson Report on Teaching Assistants

"Professor Malan gave a wonderful lecture on the stage, but other studies depend on teaching assistants." Fernandes, a former CS50 teaching assistant, expressed his opinion. "In essence, it is the teaching assistant who propped up this course."

Managing the professor’s office hours, leading small tutoring and attending weekly staff meetings are still reasonable jobs for teaching assistants. Nowadays, they have to answer questions for a long time after class and prepare most of the course materials.

These burdens have far exceeded the provisions of the school agreement-teaching assistants can be paid up to 10 hours a week, and course assistants can only calculate up to 4 hours. According to this standard, Fernandes leaves only three hours for homework review every week. Even if there are dozens of people in the teaching assistant group, each person is too busy for three hours.

Leggett, the current teaching assistant of CS50, added a "slot": "The teaching assistant has to support the exhibition of CS50′ s works, but often the day after tomorrow is our own final exam of advanced computer science. The agreement never mentioned this time conflict, and the consequences can only be borne by ourselves."

In this case, CS50 is no exception. Introduction to probability and comprehensive introduction to life science are all the same.

In addition to the dissatisfaction of the student teaching assistants, the students of elective courses also suffered a lot of "dumb losses".

Harvard’s admissions website reads, "As world-class educators, professors work side by side with students to encourage them to look at problems with new eyes." However, many Harvard students feel that they are just the audience who listen to the professor’s lectures. If you really want to say that students work side by side, it is still the teaching assistant.

"Although it is indeed possible for students to have direct contact with some of the greatest scholars in the world, this opportunity is much smaller than it seems." "Harvard Crimson" commented.

What’s more, teaching assistants are students after all. No matter how much they love their subjects, there is a real gap between them and professors in knowledge, thinking and teaching.

Some students who have taken the introductory biology course complain that the teaching assistant knows a lot, but the level of counseling is worrying, and she can’t paraphrase complex concepts into expressions that she can understand. Finally, she is left to recite and memorize.

There are also teaching assistants who are limited by knowledge storage and understanding, and their opinions are contradictory to those of professors, which is simply worse for students who have doubts.

Kyle Waldman, who is studying for a doctorate, said that unless it is a small class or the students themselves are extroverted, it is "difficult for professors to interact with students continuously". Compared with smaller schools, Harvard students are "disadvantaged".

Students want more counseling, teaching assistants call for less work, and professors find it difficult to find a balance between research and teaching. The contradiction between students’ needs and the cost of manpower and time is becoming more and more prominent.

Since students cannot be banned from using AI,

It’s better to "turn an enemy into a friend" and take advantage of AI.

Malan asked AI teaching assistants to "put out the fire", so the way of using AI is also more "radical" among Harvard professors. But in fact, this is already slow.

Students’ hands and feet are faster than professors’ countermeasures. At the end of last year, just after ChatGPT came out of the circle, there were Harvard students driving ChatGPT and taking online open-book exams, and it was not a case.

It was not until late January that the email from the undergraduate education office arrived late, asking teachers to pay attention to the influence of ChatGPT, but no specific regulations were given, and the decision-making power was handed over to teachers.

Most professors in Harvard have a negative attitude towards the influence of AI technology, so many classes are forbidden to use ChatGPT, such as religion, Spanish and physics.

More teachers realize that it is impossible to ban it completely, so they try their best to reduce students’ chances of using ChatGPT and push them to learn by themselves.

Previously, the main assessment of French classes was done in the classroom, which restricted students from using Google Translate as a tool. After the popularity of ChatGPT, Amanda Gann, a lecturer, changed the final evaluation to "paper+dialogue", asking questions at any time to prevent students from writing a draft in advance with ChatGPT.

Gann admits that if it weren’t for ChatGPT, oral evaluation wouldn’t have such an important position as it is now. This also inspired her to reflect on her homework: "Is this something that only humans can do?" "How to make students not want to use AI to complete it from the beginning?"

As heroes think, so thought Bruce. Boaz Barak, a professor of computer science, also made homework and exams more difficult.

In the past, writing a simple neural network code was enough to complete an assignment; But now, students should reproduce a more complex code inspired by cutting-edge research. "Since students have access to more advanced tools, I naturally have to ask for more."

Professor Maria Dikcis of "English: The Dark Side of Big Data" went one step further and encouraged students to use ChatGPT critically. In her homework, she tried to make students compete with machine intelligence: the students wrote a short analysis article first, then generated a paper on the same topic with ChatGPT, and then compared the two articles. She hopes that students can see the shortcomings behind the brilliant appearance of AI and think about the significance and value of these shortcomings.

In contrast, the AI teaching assistants of CS50 have a feeling of "turning enemies into friends". Teachers are worried that students use AI because ChatGPT is so easy to use, so it is better to use this in turn and make AI a 24-hour online teaching assistant.

This idea is also in line with the personalized learning experience that Malan has been exploring. In order to keep students with different levels interested in CS50 all the time, Malan and teaching assistants designed assignments with different difficulties.

Statistics of Students’ Learning Feeling in CS50 Course & Hierarchical Homework Design

For example, students with weak ability to design filters for pictures can write a black-and-white filter, while students with strong ability can challenge the filter of film negative+reverse color.

Students of different levels can freely choose the difficulty of homework.

But the problem of students has been solved, and the time contradiction of teaching assistants still exists. They spend a lot of time commenting on homework. It takes less than 14 seconds for students to read the comments. After revision, it takes a long time to get a reply. "This is not an efficient way for teaching assistants and students to use their time." Malan said.

And the convenience of AI is like the missing piece of puzzle. Therefore, Malan makes AI teaching assistants undertake a lot of procedural and repetitive work. Although the revised opinions of AI teaching assistants still smell like robots, they hit the nail on the head to find the problem and give a detailed explanation, but they also got the evaluation of "weirdly informative".

CS50 Bot under test

AI teaching assistant is a large-scale technical test, and it also shows students how to use AI reasonably. After that, Malan also hopes to integrate AI technology into other STEM classes and even humanities classes, bringing some changes to teaching.

Be the master of learning or the puppet of technology?

AI is a sword of Damocles.

However, the change of teaching methods still seems to be unable to solve a question-AI is coming, can human beings hold their ground and not be replaced?

The experience of Steven Pinker, a psychology professor at Harvard University, is a very intuitive answer:

As the speaker of the introductory psychology course, he was once worried that ChatGPT was strong enough to take his place until he discovered the cognitive difference between AI and human beings.

"I asked ChatGPT,’ If Mabel is alive at 9 am and 5 pm, is she still alive at noon?’ We all know that once a person dies, he can’t be resurrected, but ChatGPT replied,’ There is no information to clearly indicate whether Mabel is still alive at noon.’ It can be seen that AI does not grasp the basic facts of the world operation and lacks common sense and logic on which human beings depend. "

"Human memory and computing power are limited, and it must be admitted that AI is stronger in retrieving a large amount of information." Pinker said, but AI’s "cognition" comes from the collection of massive information, and it has not developed logical ability, which is completely different from human beings.

Steven Pinker said in an interview with Harvard Gazette.

It can be said that thinking ability is a unique advantage of human beings, and logical ability is only one of them. Whether students can exercise various thinking abilities in their study determines the result of "confrontation" with AI. On this issue, Harvard professors also emphasized the weaknesses of AI thinking ability.

Lack of critical thinking is another obvious weakness of AI at present.

The MIT Science and Technology Review issued an early reminder that because there are a lot of biased and hateful languages on the Internet, AI as a training set will further amplify these prejudices.

In addition, generating false content has always been an obvious problem for AI. In March of this year, experts from NewsGuard found that GPT-4 responded to false news 100%, and GPT-3.5 could reply to at least 20% of false news that "these statements are groundless".

NewsGuard’s report on GPT-4

In addition, GPT-4 is less "good" at programming than before, and the introduction of AI teaching assistants on CS50 has also caused some doubts. Malan himself predicted that AI teaching assistants might "occasionally perform poorly or even make mistakes" at the beginning.

However, he believes that this is precisely the opportunity for students to exercise their thinking ability. He tells students that "when receiving information, whether it is from AI or human beings, we must always think critically. Identify the authenticity of the information, evaluate the credibility, and then decide whether to accept the other party’s information. "

The ability of reasoning and thinking is also the weakness of AI, although it is very confusing.

Some students use ChatGPT to summarize the general idea of reading materials, and its word-for-word output makes people feel that it is really thinking. But is this really the case?

Soroush Saghafian, an associate professor of public policy at Harvard’s Kenny School of Politics, called this a flaw in AI. "People think that AI can think, reason, and even think that it is omnipotent, which is the result of commercial speculation."

Frankle, the chief scientist of MosaicML, an artificial intelligence startup, also verified this statement: "The purpose of developing AI by startups has always been to build a great language model product, rather than publishing and sharing knowledge, which is only an incidental effect."

Saghafian believes that students should actively interact with ChatGPT, but also understand the disadvantages of AI itself. "At that time in 2000, teachers taught students to understand the shortcomings of search engines like Google in thinking, and now they need to treat ChatGPT as well. Students should understand the difference between reasoning and simply outputting content. "

Where does human thinking ability come from? It must be in the process of learning. However, when high scores and GPA are especially needed, students will inevitably use ChatGPT to be lazy. Even Harvard professors have limited means to use, and the decision to study is ultimately in the hands of students.

Nevertheless, Harvard University and professors try their best to inspire students:

Harvard calls the meaning of learning the value of intellectual transformation.

"It will be difficult to change yourself. To learn the principles of quantum mechanics or to understand the society before the industrial revolution, we need to deconstruct and reconstruct our world view. Therefore, Harvard University not only emphasizes academic ethics, but also expects students to experience this difficult process. "

John Hamilton, a professor of German and Comparative Literature at Harvard, said something more profound:

Technology has broken all kinds of restrictions and made our life easier and more convenient. We can fly across the world, scan literacy maps, or search keywords in Google to learn anything. However, what can give us meaning in life is limitation.

If there is enough gold, we won’t care about it; If we can live forever, we won’t care too much about life. Our concern comes from our limited ability. Life without limits will eventually be worthless.

As the saying goes, people, as the name implies, should be the car as the name implies when it comes to the automobile market! As one of the few German brands, its position in the domestic market is not generally stable, both in quality and economy are very close to the people, especially under the influence of today’s price reduction frenzy, Volkswagen really spares no effort to reduce prices! For example, the following medium-sized car, the highest price reduction is as high as 78 thousand, this car is Volkswagen’s.

Because the price is close to the people, Volkswagen has always been very popular, and it is also the medium-sized company with the highest sales volume. Its annual sales volume has reached more than 170,000 units, and its monthly sales volume can be maintained at more than 15,000 units. This data is second only to the whole medium-sized market. Even if the insurance rate is only 58.2%, and even the number of failures per 100 vehicles is as high as 262, there are still many people who are willing to start this car, just because the cost performance of this car is really not generally high. The 13 cars on sale, excluding the upcoming new cars, are directly priced between 187,000 and 261,000 by manufacturers, and the terminal discount of up to 78,000 has made many people see hope. After all, the entry price of Tiguan L has directly dropped to less than 140,000.

Such a starting price in the joint venture market may only be able to start with a compact beggar version of the car, you know, even after various concessions, the starting price is 146 thousand! It shows that Tiguan L is cost-effective. Even the top-of-the-line Tiguan L is only 217,000, which is lower than the top-of-the-line CR-V. Therefore, even though Tiguan L may have some minor problems in quality, the price close to the people is enough to make everyone feel excited, so it is very worthwhile to rush into the medium-sized space. What’s more, Tiguan L is an obvious short board in the interior, and its performance in other aspects is remarkable. For example, its appearance, calm atmosphere, is a style that men love.

The design of the front face is simple and generous, and the side shows the sense of movement of the car body. The design of the lines also follows a round and full style, and the shape of the tail is heavy and solid, which are all styles that men like. However, it doesn’t feel very suitable with 17-inch wheels, but it is more comfortable with 18-inch or above wheels. What’s more, Tiguan L chose wheels with a little larger flatness ratio, and the main one was a durable one. Although Tiguan L is medium-sized, its body length is not very long, only 4735mm, which is a bit unsightly, but people have a width of 1.86 meters and a height of 1.68m, and the wheelbase is 2791mm, which is nearly 2.8, but it has provided a lot of contribution to the space.

However, because it is divided into five-seat and seven-seat layouts, the spatial performance is also different. There is no need to say that even a person who is 1.8 meters tall has a lot of room to move in, but if it is replaced by a seven-seat layout, the space of the second row of seats is also good, and the length of the second row of seats is enough to provide sufficient support for the legs. But the third row is very cramped, so it is still used for emergency! Moreover, the rear seat supports reclining, so the storage space will be very large, and the maximum volume can reach about 1800L. It is no problem to put down two people. Those who want to go out to go on road trip can rest assured to start with this car. However, compared with the space and appearance, the interior of Tiguan L is a bit unsatisfactory.

Its overall interior style is still a familiar formula. The pure black interior is very calm, but it also loses its sense of fashion. The 12-inch central control panel is equipped with complete functions, such as car phone or voice recognition, but the car system may not be smooth enough, and occasionally there will be some jams or connection errors. There is also a good performance in the configuration. Six airbags are standard, and full-speed adaptive cruise is also standard, like auxiliary images. Many common configurations are worthy of the price of this car even if they fail to meet the standard. In terms of motivation, Tiguan L is also confident.

Although the starting point is only 1.5T, it has 160 horsepower, while the 2.0T displacement has 186 and 220 horsepower. Three different powers can easily meet everyone’s daily needs. The gearbox is a general-purpose 7-speed wet dual-clutch gearbox. Although it often causes some setbacks or a little slow start, there is no way to save fuel. Even so, the fuel consumption of Tiguan L is not low, and it is about 6.6L when starting, and it is still 95 # oil. If it actually runs, the fuel consumption will be at least 8, which is acceptable for a medium-sized car. After all, Tiguan L only has a curb weight of 1.7 tons, so it is more fuel-efficient.

It can be said that this Tiguan L is a car with obvious advantages and disadvantages. In addition to the simple interior, it is not very good at sound insulation, and the tire noise and wind noise are a bit big. So is this Tiguan L an ideal model for everyone? Ok, this Volkswagen Tiguan L is introduced here first. Welcome to leave a message. See you next time. Bye!

Super Safe Deep Blue Super Extended Range makes you feel safe at all times.

The survey shows that the biggest anxiety of fuel vehicle users entering the era of intelligent electric vehicles comes from the anxiety of refueling and mileage on the one hand, and the distrust of battery attenuation and safety on the other hand.

Deep blue super range extender adopts Admiralty battery, based on iBC digital battery housekeeper, and realizes 24-hour all-round battery monitoring through 2 types of digital pre-control management technology groups and 7 types of digital temperature control management technology groups. Among them, the battery pack adopts IP3X short-circuit protection design, and the protection level is five times higher than the national standard. The unique battery sentry mode can detect the battery status in real time through U/T inspection, which can ensure the battery safety regardless of the vehicle’s driving, charging and static state. Multi-dimensional system safety design based on intrinsic safety, passive safety and active safety ensures that the battery does not catch fire and effectively avoids thermal runaway.

In this regard, Zeng Yuqun, the chairman of Contemporary Amperex Technology Co., Limited, an industry authority, gave high praise and recognition, and said that he would continue to join hands with Shenlan Technology and global partners to build the safest car in the world and let safer new energy vehicles run all over the world.

In addition to the safety guarantee of its own battery, Deep Blue Automobile is the first owner to meet the requirements of Deep Blue Ultra-Extended Range Power System, and provides lifetime warranties such as Super Electric Drive of the Force, Intelligent Range Extender of the Force, Admiralty Battery, etc., to provide more reliable guarantee for users’ vehicle safety.

For drivers and passengers, the Deep Blue Super Range Extender also provides automatic emergency braking (AEB), lane departure warning (LDW), 540 transparent chassis and surrounding high-strength body, providing all-round active and passive intelligent safety protection. It is worth mentioning that the new version of C-NCAP five-star safety evaluation was obtained in the evaluation released by China Automotive Technology and Research Center on November 15th. Among them, pedestrian automatic braking, two-wheeled vehicle automatic braking and lane keeping ability all rank in the top 20%, which is at the top level in the industry. With the fortress-level intelligent care, the deep blue super range extender can ensure the safety of users even under complex road conditions and working conditions.
