In this era of information explosion, the Internet has penetrated into every corner of our lives, connecting all the people in the world through the Internet. The emergence of the mobile Internet has further enabled people to obtain information and communicate more conveniently. The rise of the Internet of Things connects everything and realizes the intelligent interaction between human beings and objects.

The arrival of 5G has opened up a brand-new network era, allowing us to see a broader future. The continuous development of artificial intelligence and quantum computing technology makes our fantasy of the ultimate future more real and possible.

In the vast world of the Internet, we can swim freely, get information, communicate and help business innovation. The mobile Internet liberates us in time and space, allowing us to enjoy the convenience brought by the Internet at any time and anywhere.

The intelligent interaction of the Internet of Things breaks through the barrier between man and machine, allowing us to interact with smart items magically. 5G gives us brand-new wireless communication capabilities, allowing us to enjoy the convenience brought by the Internet more quickly; With the development of artificial intelligence and quantum computing, we can master more technologies and tools to better cope with future challenges.

However, the development of these technologies and tools constantly reminds us that the challenges we face are not only technical, but also more influenced by multiple factors such as morality, society and politics. How to make good use of these technologies, how to avoid the negative effects they bring to us, and how to safeguard the future of mankind are the problems we need to think about and solve at present.

Therefore, I think we need to deeply understand the great power of Internet, mobile Internet, Internet of Things, 5G, artificial intelligence and quantum computing technology. Face up to the challenges and difficulties in technological development. While technology is constantly innovating, we should not forget the balanced development of technology and social ethics. Make the future smarter and more sustainable.

Malouda： ＂I hope Chelsea sign Mbappé＂

Malouda: "I hope Chelsea sign Mbappé"

Former Chelsea striker Florent Malouda says he would like to see Paris Saint-Germain striker Kylian Mbappé move to London.

"I hope Chelsea sign Mbappé, and I think the club should choose the best player like him. Especially when I see how much money Chelsea has spent on others. It all depends on his desire to come to the club, but we must choose such a top player and build a team around him. My dream is to build a team with young players around Mbappé. He has won many trophies and is eager for more, so Chelsea should look for such players. Will Mbappé agree to move to Chelsea? Anything is possible! "It’s not just about preparing an offer with a lot of money," Goal quoted Malouda as saying.

Mbappé has been playing for Paris Saint-Germain since 2018. The 24-year-old Frenchman’s contract will last until the summer of 2025.

This season, Mbappé made 30 appearances in various competitions on behalf of the club, scored 7 goals and sent 31 assists.

Asia-Africa World Cup competition： the group advanced and the number of semi-finals tied, and Africa won by one advantage.

In the history of the World Cup, the bipolar status of Europe and South America is unshakable. At present, all the World Cup champions come from these two regions, while teams from other continents, not to mention winning the championship, have not even stepped on the final venue yet. Relatively speaking, Asia and Africa are relatively close. There are more countries in both continents, and the number of World Cup places is similar. Africa has five and Asia has 4.5. That is to say, if Asian teams are lucky, winning the transcontinental play-offs will make the number of Asian and African teams in the World Cup the same.

So, who has the better World Cup performance in Asia and Africa in history?

Of course, we don’t need to calculate the total score or total goal data of all Asian teams and African teams in history, just look at the results of key nodes. Specifically, look at the teams on two continents, the number of times the group advanced, and the best results.

In these two aspects, Asia and Africa actually tied.

Historically, both Asian teams and African teams have been promoted 11 times. Of course, it needs to be said here that Asia in football refers to the AFC, so Australia is also counted as an Asian team.

Let’s list the specific situation below. In the history of the World Cup, African teams promoted by the group included Morocco in 1986, Cameroon in 1990, Nigeria in 1994, Nigeria in 1998, Senegal in 2002, Ghana in 2006, Ghana in 10 years, Nigeria and Algeria in 14 years and Senegal and Morocco in 22 years. A total of 11 times.

As for Asian teams, Japan has four times, South Korea has three times, North Korea and Saudi Arabia each once, and Australia twice. It happened to be 11 times. I am ashamed to say that this data, if Australia did not join the AFC from Oceania, then Asian teams actually lagged behind African teams.

Let’s look at the best results. Originally, South Korea reached the semi-finals in the 2002 World Cup and won the fourth place, which was once the unattainable achievement of second-rate teams such as Asia and Africa. But FIFA World Cup Qatar 2022 and Morocco have also achieved this. And to tell the truth, Morocco, the fourth place, is more convincing than South Korea in those days. Everyone knows this, and there is no need to start talking about it.

Therefore, in terms of the best results of the World Cup, Asia and Africa also tied.

So, which side of the world cup is better? There is a data that Africa is dominant, and with this data, we can say that African teams have higher ceilings and stronger ability to work miracles than Asian teams.

In fact, the data of the previous group promotion times is very general. After all, reaching the top 16 and reaching the top four are both group qualifying, but the gap between these two results is not small. So we might as well break it down again-the number of times we scored in the top eight.

In this regard, Africa is far better than Asia. Because Cameroon in 1990, Senegal in 2002 and Ghana in 10 years all reached the quarterfinals of the World Cup, and the number of quarterfinals was three times. What about Asia? It is still zero.

It should be noted that in the 1966 World Cup, North Korea reached the quarter-finals, but at that time, the World Cup was only 16 teams. Therefore, the quarter-finals of North Korea should be strictly called the first round of the knockout round, but it is actually the same level as the next sixteen. You know, Cameroon, Senegal and Ghana reached the second round of the knockout round, so North Korea, the quarter-finals, is not included in this data.

In today’s scale, reaching the quarter-finals means that the group will go further than the group. If it’s a miracle to beat the Asian and African teams into the knockout stage, then the miracle of the quarter-finals is certainly higher than the miracle of the quarter-finals. In fact, if we take away the controversial semi-final result of South Korea in 2002, we will find that the upper limit of Asian teams in the World Cup is not high, and the best result so far is the first round of elimination. So at this point, there is still a gap between Asian teams and African teams.

Of course, judging from FIFA World Cup Qatar 2022’s performance, Asian teams seem to be better than African teams. I hope there will be an Asian team in the future that can break through the long-standing ceiling.

Appeal failed, suspended for 2 games+fine of 10,000! Mourinho’s 1 move was praised, and the Italian Football Association was helpless

In the early morning of March 11th, Beijing time, after the Italian National Sports Court of Appeal announced that Mourinho’s appeal failed, he was suspended for two games and fined 10,000 euros, the Portuguese updated their social platform and made a gesture of being handcuffed.

The Italian media interpreted Mourinho’s action as a protest against the rejection of the ban appeal. Many fans praised the madman’s behavior and thought that he dared to challenge the hidden rules and the authority.

Mourinho knows the heat. When he showed this controversial gesture, he also brought three advertisements. He loved Adidas, Hublot and MATILDE, a jewelry brand founded by his eldest daughter. The latest development of the Rome coach has attracted nearly 280,000 likes in just 4 hours, and there should be tens of millions of views.

Mourinho handcuffed the camera off the court when he was coaching Inter Milan. At that time, he was suspended for three games by the Italian Football Association and fined 40,000 euros. However, Mourinho’s handcuff action this time seems to be carrying goods, and there is no actual evidence to prove that he is provocative, so the Italian Football Association should not do anything about him.

Mourinho was suspended this time because of a fierce language conflict with the fourth official in the 1-2 defeat to the bottom team cremona 10 days ago. Because of the appeal, Mourinho’s suspension was suspended, so he can still lead the team to play Juventus at home in the last round. Now, Mourinho’s appeal has been rejected and he will miss the next two Serie A games against Lazio and Sampdoria.

Olympic knowledge： Are there any football events in the Olympic Games？

There are football events in the Olympic Games.

Olympic Games refers to the Olympic Games, which is sponsored by the International Olympic Committee, the largest comprehensive sports meeting in the world and the most influential sports event in the world.

The history of the Olympic Games can be traced back to ancient Greece more than two thousand years ago, but the modern Olympic Games began in 1896. At the end of 19th century, Frenchman Coubertin put forward the initiative of hosting the modern Olympic Games, which was also held under his efforts, so Coubertin was also called "the father of modern Olympics".

On June 23, 1894, when Coubertin and 79 representatives from 12 countries decided to establish the International Olympic Committee and create the Olympic Movement, this feat was once the object of irony, but now the Olympic Games has become a festival celebrated by all, and the Olympic Movement has attracted the enthusiasm of 202 countries and regions.

The Olympic Committee decided to hold the first modern Olympic Games in 1896, and the venue was Athens, Greece.

Subsequently, the Olympic Games kept its frequency every four years, but there were four special events:

1. The Olympic Games in 1916, 1940 and 1944 were suspended due to world wars;

2. The 2020 Tokyo Olympic Games was postponed to 2021 due to the epidemic.

In the continuous development, the number of Olympic events is also increasing. In 2021, the Tokyo Olympic Games set up 33 major events and 339 minor events, and finally produced 339 gold medals.

Football competition is one of the earliest events in the Olympic Games. By the Atlanta Olympic Games in 1996, women’s events were added to the football competition. So far, the Olympic football competition was divided into men’s football competition and women’s football competition.

However, the Olympic football events are limited by the entry conditions. In 1992, the International Olympic Committee compromised with FIFA, and the Olympic football game became a game for players under 23. In 1993, the International Olympic Committee and FIFA reached an agreement: FIFA respected the age limit of 23, and FIFA allowed each team to have three over-age players.

It is worth mentioning that in the women’s football competition of the 1996 Olympic Games, the China women’s football team lost to the American women’s football team in the final and won the silver medal. The China women’s football team who participated in the Olympic Games for the first time set a good record. In contrast, from the first Olympic Games to the 32nd Tokyo Olympic Games, China men’s soccer team participated in the Olympic Games twice, once in 1988, and was shortlisted by virtue of its strength; Once in 2008, I was shortlisted as the host.

At the 2020 Tokyo Olympic Games, Brazil won the gold medal, while Spain, Mexico and Japan won 2-4 respectively. The Canadian women’s football team won the gold medal, while Sweden, the United States and Australia won 2-4 respectively.

The above is an introduction about Olympic football.

When artificial intelligence robots and virtual people are fully stationed in e-commerce, it will set off a new climax of e-commerce delivery.

Why do humans study hard? Maybe some parents will say, find a good job in the future. Then why did you find a job? I think the first thing to find a good job is to earn more money, and then to realize other dreams and ideals. But when the era of artificial intelligence comes, does all the efforts still make sense? Maybe you think so, but when you see more robots working in factories, don’t those workers work hard? Why only see robots? I can’t see the human figure,

Therefore, it may be meaningless to work hard in the future. Offline work has been done by robots. Let’s look online again. Now more and more virtual people are beginning to appear on large and small platforms, and it is said that robot chat system is also integrated. With the algorithm and analysis of artificial intelligence, these virtual people and robots may try to figure out your mind. To put it bluntly, robots have learned psychology. If a large number of such robots come to live online to bring goods, and they never need to rest, do you think they will sell better than these real people now?

Everything is difficult at the beginning. Actually, I’m not absolutely difficult. The people selling goods are not real people. How can it be difficult? It’s just that users feel unaccustomed and unfamiliar. But after a long time when users get used to it, this kind of virtual people will be accepted, and if there are few virtual beauties, they will also attract handsome guys ~ They have joined the intelligent technology, and they will become smarter and even smarter than human beings. A small amount may not shake the stage of the current e-commerce world. If a large number of intelligent virtual robots come online to carry goods around the clock, and all platforms have them, let this large number of virtual people spend a lot of time occupying a large number of e-commerce platforms. If there is only one person behind them, will this person become the next richest man in China?

I think robots can replace human work offline, and they can certainly do it online. Because we have long acknowledged that artificial intelligence has surpassed human intelligence. Offline replaces human physical work, and online may replace human mental work. Robots are further evolving, from super physical strength to intelligence quotient. Besides playing chess, I think many places can beat us. Although robots are imitating human wisdom, robot calculation is more accurate than human beings, and robots are also making progress in learning human emotions, language and communication. If there are a large number of robots with goods, maybe the people behind them are really the next richest man in China.

Technical password of generated image AI

In the past few years, artificial intelligence (AI) has made great progress, and AI’s new products include AI image generator. This is a tool that can convert input statements into images. There are many AI tools for text-to-image conversion, but the most prominent ones are DALL-E 2, Stable Diffusion and Midjourney.

DALL-E 2 is developed by OpenAI and the project of chatgpt is complementary. It generates images through a paragraph of text description. Its GPT-3 converter model trained with more than 10 billion parameters can interpret natural language input and generate corresponding images.

DALL-E 2 mainly consists of two parts-converting user input into a representation of an image (called Prior), and then converting this representation into an actual photo (called Decoder).

The text and images used in it are embedded in another network called CLIP (Contrast Language-Image Pre-training), which is also developed by OpenAI. CLIP is a neural network that returns the best title for the input image. What it does is the opposite of what DALL-E 2 does-it converts images into text, while DALL-E 2 converts text into images. The purpose of introducing CLIP is to learn the connection between visual and text representation of objects.

DALL-E 2′ s job is to train two models. The first one is Prior, which accepts text labels and creates CLIP image embedding. The second is Decoder, which accepts CLIP image embedding and generates images. After the model training is completed, the reasoning process is as follows:

  • The input text is converted into CLIP text embedding using neural network.

  • Use Principal Component Analysis to reduce the dimension of text embedding.

  • Create an image embedding using text embedding.

  • After entering the Decoder step, the diffusion model is used to embed the image into an image.

  • The image is enlarged from 64×64 to 256×256, and finally enlarged to 1024×1024 by using convolutional neural network.

Stable Diffusion is a text-to-image model, which uses CLIP ViT-L/14 text encoder and can adjust the model through text prompts. It separates the imaging process into a "diffusion" process at runtime-starting from the noisy situation, gradually improving the image until there is no noise at all, and gradually approaching the provided text description.

Stable Diffusion is based on Latent Diffusion Model(LDM), which is a top-notch text-to-image synthesis technology. Before understanding the working principle of LDM, let’s look at what is diffusion model and why we need LDM.

Diffusion Models, DM) is a generation model based on Transformer, which samples a piece of data (such as an image) and gradually increases the noise over time until the data cannot be recognized. This model tries to return the image to its original form, and in the process, it learns how to generate pictures or other data.

The problem of DM is that powerful DM often consumes a lot of GPU resources, and the cost of reasoning is quite high due to Sequential Evaluations. In order to train DM on limited computing resources without affecting its quality and flexibility, Stable Diffusion applies DM to powerful Pre-trained Autoencoders.

On this premise, the diffusion model is trained, which makes it possible to achieve an optimal balance between reducing complexity and preserving data details, and significantly improves the visual reality. The cross attention layer is introduced into the model structure, which makes the diffusion model a powerful and flexible generator and realizes the high-resolution image generation based on convolution.

Midjourney is also a tool driven by artificial intelligence, which can generate images according to the user’s prompts. MidJourney is good at adapting to the actual artistic style and creating images with any combination of effects that users want. It is good at environmental effects, especially fantasy and science fiction scenes, which look like the artistic effects of games.

DALL-E 2 uses millions of image data for training, and its output results are more mature, which is very suitable for enterprises to use. When there are more than two characters, the image generated by DALL-E 2 is much better than that generated by Midjourney or Stable Diffusion.

Midjourney is a tool famous for its artistic style. Midjourney uses its Discord robot to send and receive requests for AI servers, and almost everything happens on Discord. The resulting image rarely looks like a photo, it seems to be more like a painting.

Stable Diffusion is an open source model that everyone can use. It has a good understanding of contemporary art images and can produce works of art full of details. However, it needs to explain the complex prompt. Stable Diffusion is more suitable for generating complex and creative illustrations. However, there are some shortcomings in creating general images.

Real Madrid is very worried about the findings of the procuratorate, and the emergency meeting will allow the club to appear in court.

[Real Madrid is very worried about the investigation results of the procuratorate, and the emergency meeting will allow the club to appear in court] real madrid cf recently issued a statement, saying that it will hold an emergency general meeting at noon on March 12, local time, regarding the fact that Barcelona Football Club was prosecuted by the local procuratorate in Barcelona for bribing referees for corruption.

According to AS reporter, former Real Madrid press officer Joaquín Maroto confirmed from Real Madrid sources that this general meeting will vote to approve Real Madrid to testify in this case. Real Madrid told AS that "there has been no action before because they are waiting for the judicial department to complete their work. Now that the procuratorate has submitted their appeal, it is time for Real Madrid to appear in court.

Real Madrid announced the announcement just 24 hours after the procuratorate filed an appeal, just when the Spanish Central Procuratorate accepted the prosecution of the Barcelona Procuratorate. Prior to this, Real Madrid had been patiently waiting for the judicial department to complete their work. At present, Real Madrid is very worried about the conclusion reached by the procuratorate on this matter.
