More and more people are using artificial intelligence program ChatGPT to create books for sale. Despite the slow sales so far, many writers are still worried that the books created by ChatGPT may harm the writing and publishing industry.

1. ChatGPT helps create children’s books.

Until recently, Schickler never thought that he could be a published writer. But after learning about ChatGPT artificial intelligence program, Schickler thinks he has a good chance.

ChatGPT logo appeared in March 2023.

The idea of writing a book seems to be finally possible. Using artificial intelligence software, Schickler created a 30-page illustrated children’s e-book in a few hours. He sold it through Amazon’s self-publishing section in January. The e-book titled The Wise Little Squirrel: A Tale of Saving and Investing made Schickler less than $100. Although this may not sound like much, it is enough to make him want to use the software to create other books.

As of mid-2000, there were more than 200 e-books in Amazon’s Kindle store that said ChatGPT was a writer or co-writer. And this number is rising every day. However, due to the nature of ChatGPT and many writers don’t admit that they have used it, it is almost impossible to fully count how many e-books AI can write.

2. Influence

Some professional writers began to worry about the possible impact of ChatGPT on the book publishing industry.

Mary Rasenberger is the executive director of the Writer Guild. She said: "This is what we really need to worry about. These books will flood into the market and many authors will lose their jobs." Rasenberger pointed out that the industry has a long tradition of ghostwriting, an accepted practice, that is, paying someone to write a book or give a speech in the name of another author. But she is worried that the ability to create with artificial intelligence may turn writing a book from an art into a commodity-a simple raw material that can be bought and sold.

Amazon did not disclose whether it plans to change or study the policy on the use of artificial intelligence or other automatic writing tools by authors. Lindsay Hamilton, a spokesperson for Amazon, said by email that books in stores must comply with its guidelines on "intellectual property rights" and other laws.

3. Quick release

Amazon is by far the biggest seller of physical books and e-books. Its sales in the United States account for more than half, and it is estimated that it accounts for more than 80% of the e-book market. In 2007, Amazon created Kindle Direct Publishing, so that anyone can sell and market a book without looking for a book agent or publishing house. Generally speaking, Amazon allows authors to publish without any supervision. Then, the company shares any money with the writer.

This service has attracted new artificial intelligence assistant writers like Kamil Banc to join Amazon. He told his wife that he could write a book in less than a day. Using artificial intelligence image creator ChatGPT and instructions such as "Write a bedtime story about pink dolphins and teach children how to be honest", Banc published a 27-page inserted book in July.

Since then, Banc has published two more books generated by artificial intelligence, including an adult picture book, and more works are being published. He said, "It’s actually very simple, and I’m surprised at its speed from concept to release.".

Not everyone is impressed by the software. According to reports, Mark Dawson sold millions of books written by himself through Kindle Direct Publishing. He said that ChatGPT-assisted novels were "boring", and boring meant boring.

Advantages-a commendable good quality-are very important in the book industry, and advantages play a role in how to recommend books to other readers. If a book gets a bad review because of its boring writing, it will soon sink to the bottom.

Uzbekistan’s U20 Asian Cup has entered the quarter-finals, and the first match was between the Iranian men’s soccer team and the Iraqi men’s soccer team. In the end, relying on the goal in the 91st minute of the second half, Iraq eliminated Iran 1-0, becoming the first team to advance to the semi-finals, and at the same time locked in the qualification for the World Youth Championship. China’s men’s soccer team will play in the quarter-finals on the next match day, and the winner can also advance to the World Youth Championship against the Korean men’s soccer team.

In the history of the Asian Youth Championship, Iraq participated in a total of 17 competitions and won the championship five times in total. The last time was in 2000, and Iran also won the cup four times, but the winning experience was in the last century.

In the group stage, Iran scored 6 points with 2 wins and 1 loss. Finally, compared with Australia and Vietnam, the goal difference was superior to each other, and it won the first place in the group. Iraq scored 4 points with 1 win, 1 draw and 1 loss, which forced Indonesia to lock in the second place because of the winning or losing relationship. According to the regulations of AFC, the top four teams in this tournament have advanced to the 2023 World Youth Championship, so whoever wins this game will be locked in the ticket for the World Youth Championship.

This is a close confrontation. The national team and the youth team of Iran and Iraq are in fierce confrontation. Now, the Asian Youth Championship is contested. The two teams did not rewrite the score in the first 90 minutes, and the scene is almost 50-50.

In the 91st minute, Ali Jassim broke into the restricted area with the ball and scored a goal from the far corner with a low shot, helping the Iraqi team to complete the lore 1-0. After the goal was scored, the players thumped and celebrated wildly, and then they roared to the sky and were very excited. After the game, the whole team celebrated like winning the championship.

The contest between China and South Korea will start at 18 o’clock tomorrow night, and the winner can also advance to the finals of the 2023 World Youth Championship.

According to statistics, the two teams have played against each other 18 times in history. The men’s soccer team in China has scored 3 wins, 2 draws and 13 losses, which is obviously at a disadvantage. At the same time, in the last 8 games, it has not won, and it has not won the Korean men’s soccer team for 18 consecutive years. In addition, compared with China’s men’s soccer team, the Korean men’s soccer team won the cup 12 times, which is the most successful team in the history of Asian Youth Championship, so it is very difficult to win by surprise.

Nevertheless, China men’s soccer players are not afraid of this opponent. It is reported that after the successful team of China Men’s Football Team qualified, they celebrated with the fans at the scene. The fans shouted loudly in the stands: "The next game is going to play South Korea", and some players responded: "Kill South Korea! We are going to the World Youth Championship! "

It is certainly a good thing to have confidence, which gives fans more expectation. The last time China men’s soccer team participated in the World Youth Championship was in 2005, and it has been 18 years since now.

As we all know, football is a very physical competitive sport, so it requires high physical conditions for players. So this sport has basically become a young player’s sport, because football players will basically have a decline in their ability as long as they are over 30 years old, so they will start to stay away from the pitch step by step.

However, there are some players who are different from most people. They are against the trend of growth. They were average when they were young, but suddenly broke out around the age of 30, becoming the main force of the team and even entering the national team. For example, a typical example is the striker Valdi of the Premier League leicester city team. Before the age of 30, he was still playing in the low-level league, and he was unknown. By the age of 30, he became a big killer of the Super League and entered the English national team. It is also considered as a representative of being a late bloomer.

There are also such players in our football in China. A typical example is Tan Long of Changchun Yatai Team. Tan Long spent most of his career in the United States. He was the first China player in the Major League of America. However, no matter how he played in the United States, he never got the call-up of the national football team. So he returned to the Super League in the 2014 season, that is, when he was 25 years old, and joined the Super League team Harbin Yiteng. However, in Yi Teng’s team, Tan Long’s performance was just so-so, playing 7 games and starting 4 games for the team, with no goals and assists. So he soon returned to America.

Finally, in the 2017 season, Tan Long returned to China again and joined the Changchun Yatai team, and this time he succeeded. He became the main striker of Yatai team through his own efforts. He played 29 games for the team this season, including 22 starts, 8 goals and 6 assists. Thanks to his outstanding performance in the league, Tan Long was successfully selected for the national team at the age of 29, and represented the national football team in the China Cup.

Moreover, Tan Long later fell into the Chinese League with Yatai, and then helped Yatai return to the Super League, and he also won the golden boots of the Chinese League. It can be said that Tan Long is more and more demon, and the more he plays, the more reliable he is. And now Tan Long will be 35 years old, but he is still the best choice for the position of national football center. No one is more reliable than Zhang Yuning.

Recently, what is surprising is that in Changchun Yatai team, we saw the appearance of another Tan Long. This new Tan Long is Yatai’s 31-year-old native gun Cheng Changcheng. On the evening of 10th, Changchun Yatai team played a warm-up match with Wuhan Sanzhen team, the defending champion of Chinese Super League. As a result, Changchun Yatai team’s all-China squad defeated the opponent’s double foreign aid squad 3-1. Among them, Cheng Changcheng was the best performer, who scored twice in the competition and directed the victory directly.

It is worth noting that Cheng Changcheng was produced by Changchun Yatai Youth Training, and he has been a substitute for Yatai team for more than ten seasons. Before the 2022 season, he rarely played in the league and was basically a substitute for foreign aid. The places where he can show his ability are the reserve league and the pre-season warm-up match. And Cheng Changcheng has also won the silver boots in the reserve league, and in the annual pre-season warm-up matches, he has outstanding performance, always scoring twice or scoring a hat trick in the game, and even staged a big four-happiness, which is more popular than foreign aid. But once in the league, he can’t play.

However, last season, because Yatai’s striker was really out of form, Cheng Changcheng finally got the chance. He played 10 games for the team, including 6 starts, and scored 3 goals. It is worth noting that Cheng Changcheng scored his first league goal in his career this season. After the goal, he was also in tears, excited and bitter, and there were mixed feelings at that moment.

And just before the team assembled, Cheng Changcheng and Tan Long also took the initiative to practice, and invited the champion of the 400-meter hurdles in the National Games to help them train. This is why he can perform well in the warm-up match. Where there is a will, there is a way. We are also looking forward to Cheng Changcheng’s performance in the new season. Maybe he is the new Tan Long of Yatai.

Besides Cheng Changcheng, do you know any other players who are late bloomers in the Super League? Welcome friends to discuss together in the comment area!

Wang Xing, the founder of Meituan, plans to vote for another brother.

On March 8, Wang Xing released a circle of friends and revealed that individuals will participate in the A-round investment of Wang Huiwen’s startup company "light years away" and serve as directors.

Wang Huiwen and Wang Xing were bunk school classmates when they were studying in Tsinghua University. Together, they founded the intranet and Meituan, and Wang Huiwen officially retired from Meituan at the end of 2020. Since then, the venture capital circle and the technology circle have been paying attention to when Wang Huiwen will come back to start a business. Until ChatGPT detonated AI, Wang Huiwen finally found a new direction.

In February this year, Wang Huiwen announced the establishment of Beijing Lightyear Beyond Technology Co., Ltd. (hereinafter referred to as "Lightyear Beyond"), and said on the social platform that "China OpenAI should be built". Regarding the old classmate’s decision, Wang Xing bluntly said, "Lao Wang and I have been on the road to entrepreneurship for nearly 20 years. Since he is determined to embrace this big wave, I must support it."

According to the radar finance, Internet tycoons are used to the road of "innovating and investing", and Wang Xing is no exception. Investment has long been a trump card for him.

From 2014, Meituan began to invest abroad. After Meituan’s comment industry fund was renamed as Dragon Ball Investment in 2017, a "troika" of Meituan’s war investment, Dragon Ball Capital and Wang Xing’s personal investment was formed, and the investment style of Meituan also showed a trend of moving closer from the early consumer category to "hard technology".

"two kings" join hands to start a new business

The entrepreneurial story about the "two kings" of the US Mission is widely circulated in the Internet circle.

As early as 1997, Wang Xing was sent to Tsinghua University from Longyan No.1 Middle School in Fujian, and Wang Huiwen slept in Wang Xing’s lower berth in the dormitory. During his classmates, he forged a deep friendship, and Shine Wong Wen became what Wang Xing called "Lao Wang".

They majored in electronic engineering, that is, hardware, but in their second year of college, they bought a computer together and started playing games. Wang Huiwen once told Wang Xing that the current game is not good enough. It is better to learn programming to play games, and the seeds of entrepreneurship are planted.

After graduating from Tsinghua University, Wang Huiwen was sent to the Chinese Academy of Sciences for postgraduate study, but the idea of starting a business remained. The SARS in 2003 changed the fate of many people. It was also at this time that Wang Xing made a choice, decided to suspend his studies in the United States and return to China to start a business, and joined Wang Huiwen and Lai Binqiang, a middle school classmate.

After the first two entrepreneurial projects died, inspired by Facebook, their intranet (later "Renren") was officially launched at the end of 2005, and it gained millions of users in the following year.

With the rapid growth of the campus network, the team needed money to increase the server and bandwidth. At that time, Sequoia Capital wanted to invest, but because Wang Xing had not figured out how to make a profit on the campus network, Sequoia turned to invest in Zhanzuo.

Later, in 2006, the intranet was acquired by Thousand Oaks Interactive in Chen Yizhou for 2 million dollars, and it was renamed Renren in 2009 and successfully listed in 2011.

After selling the company and successfully cashing out, the "two kings" separated briefly. Wang Huiwen traveled around the world for a year, while Wang Xing set up a Twitter-like Fanfan website in May 2007.

In the first half of 2009, Fanfan.com had millions of registered users. However, due to an accident, all servers were forced to shut down. When I returned more than 500 days later, the same type of Weibo rose in China, but the rice declined.

After several entrepreneurial failures, Wang Xing saw the opportunity to buy a track, and Meituan.com was born in March 2010. At that time, the development of Wang Huiwen’s Taofang.com was not satisfactory. In October of that year, at the invitation of Wang Xing, Wang Huiwen officially joined the US delegation, and the "two kings" once again joined hands to start a business.

Wang Huiwen was considered to have played a vital role in the later "Thousand Regiments War" of Meituan, as well as in the important development nodes such as cutting into the take-away business, entering local life and rushing to the beach to get a car, and was dubbed by the media as the "second person" of Meituan after CEO Wang Xing.

In December 2020, Wang Huiwen, who was only 42 years old, wrote a farewell message, "Ten years, I need a rest, and the next decade will be entrusted to my brothers, thank you."

After retirement, from the content published by his personal social platform, Wang Huiwen is concerned about Crypto (cryptocurrency) and web3-related content. The reappearance in the public eye is related to ChatGPT.

On February 10 this year, Wang Huiwen released the "Declaration on Artificial Intelligence" in the circle of friends, saying that "50 million US dollars, with capital to join the group, regardless of post, salary and tittle, seeking a team."

Two days later, he added the details of his AI venture, and set up Beijing Lightyear Technology Co., Ltd., with a capital contribution of 50 million US dollars and a valuation of 200 million US dollars. 75% of the shares were all used to invite top R&D talents, and said that the top VC had subscribed for 230 million US dollars in the next round of financing.

Sky-Eye Survey shows that Beijing Lightyear Beyond Technology Co., Ltd. was established in 2018 with a registered capital of 1 million yuan, and Wang Huiwen holds 100% of the shares.

Although there is no lack of voices to pour cold water on, and that $50 million is not enough for several large-scale model trainings, Wang Xing chose to stand on the side of good brothers.

"Lao Wang and I have been on the road to entrepreneurship for nearly 20 years. Since he is determined to embrace this big wave, I must support it. I personally will participate in the A-round investment of Pharaoh’s startup company’ light years away’ and serve as a director. " On the afternoon of March 8, Wang Xing released a circle of friends.

Wang Xing also said that the AI ? ? big model made him both excited about the huge productivity to be created and worried about its future impact on the whole world.

It is understood that apart from Wang Huiwen, there are also Yan Li, a former AI core figure in Aauto Quicker, Zhou Bowen, a former technical director in JD.COM, and Wang Xiaochuan, a former Sogou CEO, who are interested in building China OpenAI.

Wang Xing’s Secret Investment Empire

As an Internet veteran, supporting Wang Huiwen’s entrepreneurship is just the latest example of Wang Xing’s many investment cases.

However, just like investing in light years, most of the projects that Wang Xing personally participated in were innovative when they were founded, and the entrepreneurs themselves were also friends of Wang Xing. Therefore, Wang Xing’s personal investment is often evaluated by the outside world as containing more human feelings.

In July 2014, Wang Xing suddenly invested in the Angel Wheel of Internet brokerage Tiger Securities. At that time, the domestic internet brokers were still in their infancy, and the prospects were not clear. The financial business of Meituan itself had not been fully rolled out, and Wang Xing’s investment once puzzled the outside world.

But in fact, Wu Tianhua, the founder of Tiger Securities, is Wang Xing’s younger brother in Tsinghua. After two people talked on the phone for about an hour, Wang Xing decided to invest in Tiger Securities.

Since then, Wang Xing has invested in projects such as Water Drop Mutual Assistance and mobike. In 2016, Shen Peng, the "No.10 employee" of Meituan, left his job and founded "Water Drop Chip". Before the launch, Water Drop Mutual Assistance received 50 million yuan in financing, among which Meituan Review was an important investor.

In October 2016, mobike completed the C+ round of financing of nearly US$ 100 million. In addition to institutions such as Gaoyou and Sequoia, the investor Wang Xing participated in the investment in his own name. Two years later, Meituan collected mobike for $2.7 billion, then fully accessed Meituan and renamed Meituan Bicycle.

In September 2017, Wang Xing and Wang Huiwen invested in the convenience of unmanned shelves in their own names. Their founder Si Jianghua served as the general manager of the culture and entertainment division of Meituan Store. Later, the former public comment COO and the president of Meituan’s comprehensive business group Lu Guangyu also joined the company.

In the same year, Lai Binqiang, who worked hard with Wang Xing, also left to start a business. When the name of an "online learning" project he did was not announced, he got the seed investment of Wang Xing and Wang Huiwen.

Wang Xing’s biggest bet is the investment in LI. It is reported that when LI was at a loss for financing in 2019, the ideal founder Li wanted to go to Wang Xing.

Wang Xing, who has already done his homework, is optimistic about the potential of electric vehicles and agrees with Li Xiang. "I think many people also underestimate the founder Li Xiang, and he will become a top entrepreneur in China in the future."

To this end, Wang Xing chose to mortgage his shares in Meituan to Goldman Sachs, and borrowed 285 million US dollars, plus 15 million US dollars from Longzhu Capital, a subsidiary of Meituan, and invested a total of 300 million US dollars in the ideal.

After additional investment in the later period, in just one year, Wang Xing and related parties of Meituan have invested more than $1.1 billion in Li Xiang. According to the financial report of Meituan in the third quarter of 2020, the return on investment brought by Meituan’s investment in LI is as high as 5.8 billion yuan.

According to media statistics, in addition to the above cases, Wang Xing’s personal investment projects include e-generation, Qingping Technology, Maibu Technology and flight steward.

The data shows that there are currently 121 affiliated enterprises and 39 foreign-invested enterprises under Wang Xing’s name, of which 34 are still in existence; Through direct or indirect shareholding, Wang Xing has actual control over 90 enterprises.

Meituan investment turns to "hard technology"

Under the internet tradition of "creating the best and investing", Meituan has become a force that cannot be ignored in the venture capital circle.

Statistics show that since 2014, Meituan has made frequent efforts in the investment field, with a total investment of about 100 projects. Only in the early stage, Meituan Zhantou closely followed the local life format and made strategic supplement through investment.

The merger of public comments in 2015 became an important starting point for the expansion of the US Mission. According to the statistics of billion euros, before the merger, Meituan Zhantou only completed six investments, involving five fields, including local life, corporate services and e-commerce.

After the merger, Meituan has invested 38 times in five years, the largest proportion is still local life (catering, beauty industry, wedding), followed by e-commerce, corporate services and tourism.

At present, as an investment institution, Meituan is mainly composed of Dragon Ball Capital, Meituan War Investment and Wang Xing’s personal investment.

Among them, Longzhu Capital was established in February 2017, formerly known as Meituan Review Industry Fund, with Chen Shaohui, senior vice president of Meituan, as CEO, and the funders including Meituan Review, Tencent Investment and New Hope Group.

As an independent investment institution, Longzhu Capital focuses on the field of large consumption, and is known as the "online celebrity Harvester in Investment Circle". The famous projects it has invested in include Xicha, Guming Milk Tea, Mannner Coffee and Happiness Cake.

It is worth noting that in recent years, the investment style of Meituan has quietly changed, expanding from the field of life service to the fields of automobile transportation, intelligent manufacturing and artificial intelligence. Starting from investing in LI, Meituan began to make frequent bets on the smart car industry chain.

In February, 2021, Meituan participated in the Pre-A round of investment of Haomo Zhixing, an autonomous driving company hatched by Great Wall Motor. Subsequently, Meituan also invested in laser radar manufacturer Wo Sai Technology, light boat Zhihang focusing on L4 unmanned minibuses, and self-driving truck enterprise Win Che Technology.

In 2022, Meituan and its related parties laid out projects in the fields of science and technology, such as future robots, Xinwangda EVB, AI vision chip research and development platform Aixin Yuanzhi, and Ling Mingguang, a single-photon sensor chip developer.

Some people in the investment community pointed out that the reversal of Meituan’s investment logic, on the one hand, shows that the growth dividend of Internet users is over, and it is difficult to have exponential growth again; On the other hand, it is also related to the core strategic transformation of Meituan to some extent.

In September 2021, Meituan upgraded its strategy from "Food+ Platform" to "retail+technology", hoping to use advanced technology to open a new breakthrough and seek new development.

This concept is reflected in the investment style. The left hand harvests online celebrity consumer brands, and the right hand grasps the underlying technology in the field of science and technology, which has become the underlying logic of Meituan’s investment in recent years.

Wang Xing once revealed his unique understanding of investment, saying that Sequoia’s investment principle is "betting on the track, not betting on the racers", but he prefers Sun Tzu’s statement that "seeking the situation and not blaming others". Combined with this homeopathic thinking, we may be able to better understand the investment behavior of "Meituan Department".

Antibiotic resistance is an increasingly serious health problem. Antimicrobial peptides (AMP) destroy harmful microorganisms through nonspecific mechanisms, making it difficult for microorganisms to develop drug resistance. Therefore, they are expected to be substitutes for traditional antibacterial drugs.

In this study, researchers from Gwangju Institute of Science and Technology (GIST) in Korea developed an improved AMP classification model called AMP-BERT.

The team proposed a deep learning model with a fine-tuned bidirectional encoder representation from Transformers(BERT) architecture, aiming at extracting structural/functional information from input peptides and identifying each input as AMP or non-AMP. The researchers compared the performance of this model with other models based on machine learning. AMP-BERT produced the best prediction results among all the models evaluated using external data sets selected by researchers.

In addition, researchers use the attention mechanism in BERT to perform interpretable feature analysis and identify specific residues in AMP that are known to contribute to peptide structure and antibacterial function. The results show that AMP-BERT can capture the structural characteristics of peptides used for model learning, so that AMP or non-AMP can be predicted from the input sequence. AMP-BERT is expected to help identify candidate AMPs for functional verification and drug development.

The study is based on "AMP-BERT: Prediction of antimicrobial peptide function based on a BERT modelThe title was published on December 3, 2022 in "Protein Science》。

In the past decades, antibiotic resistance has become a major public health problem in the world. This leads to the search for alternative methods to treat microbial infections.

One of the innovations is the discovery of antibacterial properties of some peptides. Antimicrobial peptide (AMP) is a short peptide found in most animals, plants and microorganisms, which can be used as a natural defense against infection. AMP fights against harmful bacteria through non-specific mechanism and prevents them from producing antibiotic resistance.

Despite these extraordinary abilities, the research on AMP is still hindered because the existing system for identifying candidate AMPs is like a black box, and the output is not easy to interpret for further analysis.

Now, in a breakthrough recently published by protein Science, a group of researchers from Gwangju Institute of Science and Technology, including Professor Hojung Nam and Mr Hansol Lee, put forward an AMP-BERT classification system, which uses AI-based bidirectional encoder representation from Transformers (BERT) architecture to improve the existing AMP classification model.

When asked about the motivation behind the development of the classification system, Professor Nam explained: "The abuse and overuse of antibiotics have led to the emergence of bacteria that cannot be effectively treated by these antibiotics. This not only increases human health risks, but also increases the health risks of agriculture. Therefore, we hope to develop an AMP pre-screening platform, which is not the black box of the algorithm, but can be easily explained for further research. 」

The team integrated a deep neural network based on natural language processing (NLP), which was pre-trained with billions of protein sequences and then fine-tuned with thousands of peptide sequences in the benchmark AMP database. This makes the AMP-BERT model not only extract structural and functional information from the input peptide sequence, but also distinguish AMP from non-AMP. This enhances the prediction ability and enables the model to make better classification even with external data.

The team also designed a model to assign a separate attention score to each amino acid in the input peptide sequence. Then, the attention characteristics reveal the important sub-regions of AMP, which play an important role in determining whether the peptide has antibacterial properties. In addition, the prediction results show that the applicability of AMP-BERT model even extends to invisible peptide data, and it can learn meaningful functional and structural information from these peptides.

The new AMP-BERT peptide pre-screening model can open a new door for discovering and developing AMP-based candidate drugs for the treatment of drug-resistant diseases. The important peptide subregion information provided by the prediction platform can also be used to optimize the antibiotic efficiency of peptides.

Professor Nam concluded: "As more and more AMPs are verified by experiments and new structural information is discovered by computational methods, we will be able to manufacture more effective antibiotic drugs and may prevent new pandemics from spreading around the world in the near future. 」
