The perseids

Speech recognition technology has been evolving since the release of IBM's Shoebox and Worlds of Wonder doll Julie doll. By the end of 2018, Google Assistant supports more than 30 different languages. Qualcomm has also developed a speech recognition system that recognizes words and phrases with an accuracy rate of 95%. In addition, Microsoft's intelligent voice service is more accurate and efficient than manual call services. However, although machine learning has made the development of speech recognition technology soaring, these speech recognition systems are still not perfect, and the most serious problem is geographical discrimination. According to a recent study by the Washington Post, popular smart voice assistants developed by Google and Amazon recognize non-US local accents with a 30% lower accuracy than US local accents. Companies like IBM and Microsoft use the Switchboard corpus to reduce the voice assistant's error rate. But it turns out that the...

Last Sunday, a very unusual Dota2 game tournament attracted a lot of attention. Dota is a sophisticated real-time strategy game and one of the most popular e-sports projects in the world. One of the teams in the competition has five members, Blitz, Cap, Fogged, Merlini and MoonMeander. Each ranks above 99.95. It can be said that they are one of the best Dota2 players in the world. However, their opponents defeated them in three consecutive games and won the game.A Dota2 game takes about 45 minutes, but the two games ended with 14 points and 21 points. Their opponent is a team of five neural networks developed by Elon Musk's OpenAI company, collectively known as OpenAI 5. Before the game on Sunday, the neural network had a 180-year Dota competition every day, and gradually approached the game. Its creators chose Dota as the goal of OpenAI 5 training to simulate the incredible changes and complex nature of the real world. Dota is a complex game. If artificial intelligence can ...

The rise of big data and artificial intelligence has brought a lot of convenience to our lives. When we open the news client, we are no longer seeing the same editorial recommendation, but the news that the AI ​​engine carefully prepares after learning about our daily preferences. When we open the e-commerce app, we no longer see what the merchant wants. What to sell, but what we want to buy; when we open the travel website, we are no longer seeing the overwhelming travel classics but the tailored travel routes for us. But at the same time, it also brings us some hidden worries - because everyone sees different content, will AI sell me more expensive products, or push more opinions to me? In fact, this is entirely possible. There is even a proper term in the country to describe this phenomenon as “big data killing”. But sometimes, the algorithm not only determines the price of the goods and the content of the push. As artificial intelligence is applied to public areas s...

At 4:23 pm on July 26, the Microsoft artificial intelligence robot named "Xiao Bing" sent a message in the WeChat public account "I have upgraded to the sixth generation of Xiao Bing." At the same time, Microsoft's global executive vice president Shen Xiangyang officially announced in Beijing: the sixth generation of small ice on the line. This is also the largest upgrade in history since the birth of Microsoft Xiaobing in 2014. Whether it's the underlying emotional computing framework or the externally interactive 3D look - a new "small ice" is here. At the press conference, Microsoft revealed for the first time the number of users Xiao Xiao has in the world: 660 million. In addition to WeChat, the existence of Xiao Bing has spread to the back end of Line, QQ, Xiaomi ecological chain, Netease cloud music, Huawei mobile phone and other products. The product form involves dialogue artificial intelligence robot, intelligent voice assistant, ...

Slow motion is a technique often used in today's film and television works. He can better attract the audience, let people see the details that are not visible under normal speed, bring visual impact; bring people into the mind's mind better, pass emotion. With the advancement of technology, today's mobile phones can also shoot slow motion. If you just send a circle of friends, Instagram, Slow-Motion in the iPhone camera is absolutely enough! But what if you want to shoot professional-grade slow motion? You often need a fairly high-end camera. However, the average slow-motion camera starts at 1000fps (frames per second), and thousands of dollars are normal; professional grades are up to 3000fps or even tens of thousands of fps, and the price is often tens of thousands of dollars. Not everyone can be The Slow Mo Guys... The picture above is from The Slow Mo Guys. Look, it’s not the same with a slow-motion camera with hundreds of thousands of knives... If you sw...

According to statistics, in Europe alone, the number of animals used for experiments is more than 10 million per year. Globally, it may break billions. Anatomy, toxicology experiments, drug experiments... It can be said that animals have made great sacrifices for the advancement of human medical research. Especially the white mice, which often show red eye characteristics due to illness, the number of deaths per year is even more difficult to count. In addition, many experiments do not usually anesthetize the animals, or only a small dose, in order to avoid the effects of the drug on the actual test results. The pain caused by the animals is unimaginable. Therefore, many medical freshmen who are enrolled are struggling in the face of their first anatomy class... However, due to the particularity of biological experiments, it is impossible for humans to conduct research on their own bodies, although this is the most reasonable way. Then, these pains have to be endured by anim...
