Artificial intelligence (ArTIficial Intelligence), abbreviated as AI. It is a new technical science that studies and develops theories, methods, techniques, and applications that simulate, extend, and extend human intelligence.
Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that responds in a manner similar to human intelligence. Research in this area includes robotics, speech recognition, image recognition, Natural language processing and expert systems. Since the birth of artificial intelligence, the theory and technology have become more and more mature, and the application fields have been expanding. It is conceivable that the technological products brought by artificial intelligence in the future will be the "container" of human wisdom. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can be like human thinking, and it may exceed human intelligence.
Artificial intelligence is a challenging science, and people who do this work must understand computer knowledge, psychology, and philosophy. Artificial intelligence is a very broad science that consists of different fields, such as machine learning, computer vision, etc. In general, one of the main goals of artificial intelligence research is to make machines capable of doing what is usually required by human intelligence. Complex work. But different eras and different people have different understandings of this "complex work."
Artificial intelligence is generally used as a tool to assist human work. Sweeping robots, medical robots, waiter robots, etc. are the most common forms of artificial intelligence. In fact, artificial intelligence is not just a form of robot, from the field of view, including robotics, speech recognition, image recognition, natural language processing and expert systems. Today we will look at what other products besides robots and artificial intelligence.
Google artificial intelligence project DeepMind
DeepMind, Google's R&D department in London, has developed artificial intelligence technology that can play video games on its own. The computer system based on DeepMind technology can learn at an amazing speed, quickly master the gameplay, and master the game winning method. Previously, the team called the deep Q-network learning network, only need to observe the changes in the game screen and game scores, you can analyze the game and algorithm to obtain the "customs clearance skills" and get high scores, which can reach the level of professional human players. .
At present, this system has been tested by 49 games under the same algorithm, network architecture and parameter settings. At present, it has been able to master 22 kinds of games (including Space Invaders mentioned above) and reach the level of expert game. This system further proves that artificial intelligence can learn the game skills through deep learning, and gain the same control power as humans, and even surpass humans in some aspects.
IBM Watson
Last year, IBM released Watson AnalyTIcs. Watson AnalyTIcs implements natural language-based cognitive services that provide business people with predictive and visual analysis tools on the fly. Watson AnalyTIcs will launch a free cloud-based value-added application version (Freemium Version) for use on computers and mobile devices.
Watson Analytics provides self-service analytics, including data access, data cleansing, data warehousing, helping enterprise users access and prepare data, analyzing and visualizing results based on this, providing the basis for effective action and further interaction for users. convenient.
Microsoft Artificial Intelligence Torque Chinese version
In February of this year, Microsoft released a Torque Chinese version of an artificial intelligence product tailored for gestures and voice interaction for Chinese users of the Android platform. As Microsoft's first personal intelligence product on the Android platform, and also Microsoft's first Chinese product for wearable devices, Torque's goal is to deliver the most direct and timely information with minimal interface. The birth of Torque frees the hands of Android users. Users only need to gently shake their wrists, and then say to them: "Happy Camp Host", "Where is KFC?", "Call to Zhang Yong" and other instructions. Experience easy access to information and more tasks with minimalist movements – this is Microsoft's understanding of mobile mobility, mobile productivity and efficiency.
According to Microsoft, Torque, like Microsoft's artificial intelligence products such as Xiao Bing and Xiaona, used the Bing big data platform as the underlying engine to handle the voice commands that each user uploads to the cloud via mobile phones and mobile Internet. The artificial intelligence product team of the Microsoft (Asia) Internet Engineering Institute has made special designs and localized developments for the preferences and habits of Chinese users.
Youtube automatic subtitles
In 2009, Google has used their voice recognition technology to provide real-time "Automatic Captions" on YouTube, in addition to allowing users to watch the network while avoiding interference with others. Thousands of various video content.
YouTube calls Google's Automatic Speech Recognition (ASR) to add captions to YouTube videos, a technology from Google Voice. Of course, the generated subtitles are not 100% accurate, but at least they can help you improve your listening to understand the video content, and Google will always improve the automatic speech recognition technology. This technology supports automatic subtitles in English, Japanese, Korean, Spanish, German, Italian, French, Portuguese, Russian, and Dutch.
In addition to the automatic captioning feature, YouTube has added caption time and automatic time for friends who create captions for videos, making it easier for everyone to do subtitles themselves. You just need to create a simple text file that says all the words in the video, and then Google uses automatic speech recognition technology to match the words in the text to the words they recognize, so that the accuracy is improved, and You don't have to spend too much time on subtitles.
Artificial intelligence bionic eye
The Royal Eye Hospital in Manchester, UK has successfully implemented the world's first artificial bionic eye transplant for the treatment of blindness caused by age-related macular degeneration (AMD). This artificial intelligence bionic eye device, called the Argus II, consists of two parts: the body implanted part and the part that the patient must wear in vitro. The implanted device will be implanted into the patient's retina, which contains an array of electrodes, a battery and a wireless antenna. The external device contains a pair of glasses, a built-in forward camera and radio transmitter, and a video processing unit.
The camera captures the picture directly opposite the implant and sends a signal to the video processor for processing. The processed signal is again sent back to the glasses, and the signal is received by the antenna of the implanted device through the glasses. Eventually, the video is "output" onto the electrode array, which acts as an optic nerve simulation. The resolution of the electrode array is 60 pixels, which is enough for the implanted device to track the trajectory of the object's motion, see the basic pattern and shape, or slowly read larger text. The images provided by Argus II are black and white, but the Argus development team is working hard to compile the brain brain stimulation, hoping to get the brain to receive color signals as soon as possible.
After the operation, the patient has been able to recognize vertical or horizontal lines after recovery, can recognize the face, and does not need a magnifying glass to read the newspaper. What's more interesting is that through this operation, the patient can see the sight of the eye even if he closes his eyes, which makes people feel some interesting.
In addition, the artificial intelligence eyeball developed by Second Vision, a company that develops artificial intelligence eyeballs in the United States, has also been approved for launch, which allows blind people who are completely blind to regain their sight.
News writing robot
The Associated Press began to write financial news automatically using the Wordsmith platform last summer. According to Lou Ferrara, director of business news at the Associated Press, after using algorithm-based machine news writing, the number of reports on the company’s quarterly business situation in the Associated Press’s business news will increase by 10 without adding new staff. Multiple times, from 300 to 4,400 per quarter, and at the same time will be able to “liberate†former journalists for such reports, allowing them to engage in more creative and challenging news planning and news. Source expansion work. When the system was first launched, it was still necessary to manually review the manuscript and adjust the platform. After three months, no human intervention was needed.
Bird face recognition technology developed by Cornell University
Cornell University and the VIsipedia research team developed the Merlin Bird Photo ID software, which uses computer vision recognition technology and deep machine learning to identify the types of birds that appear in various images. This is a very good software for the bird-watchers and bird lovers who are getting started. Through deep machine learning, this program can provide recognition results in seconds, and the accuracy of the first three recognition results has reached more than 90%.
The user can narrow down the recognition range by uploading a picture of the bird that does not know the kind, and boxing out the bird image to be identified. The software is able to identify known species of birds from tens of thousands of images, and the current database already contains more than 400 species of birds commonly found in North America. With the number of users, and deep machine learning, the accuracy will increase. Serge Belongie, a professor at Cornell University, said: "Computers can process images more efficiently than humans, and they can classify, index, and process large amounts of graphical detail features to identify results."
Skype real-time translation tool
Microsoft's real-time translation tool, Skype Translator, combines speech recognition technology with what Microsoft calls "deep neural networks and Microsoft's proven static machine translation technology." It can automatically translate voice calls and instant messaging messages in different languages.
Currently supports English, Spanish, Italian and Mandarin Chinese. In addition, the translation of instant messaging messages is supported in 50 languages, including French, Japanese, Arabic, Welsh, and even Klingon.
Because this translation tool integrates advanced technologies such as machine translation, speech recognition, machine learning, and big data, it is widely optimistic. It is understood that the voice recognition technology required for real-time interpretation of Skype Chinese is jointly developed by researchers from Microsoft China and the United States.
