1945 alan turing put forward the famous turing test in his paper "Insensitivity of Computing Machines", which had a far-reaching impact on the development of artificial intelligence.
195 1 year, Marvin Minsky and Dean edmonds established SNARC, a stochastic neural network simulation and reinforcement calculator.
On August 3rd, 65438+ 1955, the word "artificial intelligence" was put forward in the proposal of holding an international conference on artificial intelligence, which officially announced the birth of artificial intelligence as a discipline.
ELIZA, the first natural language program in the world, was established by Joseph Weizenbaum of MIT from 65438 to 0965.
Since the 1970s, the achievements of scientists have failed to meet the expectations of society, and there has been a sharp contradiction between the limited computer power and the rapidly increasing computing demand. Artificial intelligence enters the first winter.
198 1 year, the Ministry of International Trade and Industry of Japan provided 850 million dollars for the research of the first generation computer project.
1986 10 10 In October, David Rumelhart, Geoffrey Hinton and Ronald Williams published a landmark classic paper, Learning Representation through Error Back Propagation.
In the late 1980s, the industry did not maintain a home-based system, which was costly and had limited commercial value. Under the influence of disappointment, the investment in artificial intelligence has decreased, and the exhibition of artificial intelligence has once again entered winter.
In 2007, colleagues from Li Feifei and Princeton University started to set up ImageNet. This is a large annotated image database, which aims to help visual object recognition software do research.
In 20 10, ImageNet Large-scale Visual Recognition Challenge (ILSVCR) was officially held to compare the computing ability of people in image recognition and classification.
In the 265438+20th century, the Internet flourished, and mankind entered the "era of big data", and the computing power of computer chips was constantly adjusted and expanded. Artificial intelligence scholars began to introduce tools from other disciplines, and a large number of new mathematical models and algorithms were developed, and artificial intelligence accumulated, creating new glories and welcoming the third wave.
20 12 10 10 In October, the convolutional neural network designed by the University of Toronto achieved an error rate of 16% in the ImageNet large-scale visual recognition challenge (ILSVCR). Significantly higher than the best level of the previous year (25%).
2065438+March 2006, AlphaGo researched by Google DeepMind defeated Li Shizhen, a Korean professional nine-stage player, in the man-machine battle of Go. 20 17 defeated China's No.1 player Ke Jie.
20 18 artificial intelligence has become one of the hottest scientific and technological topics, with significant commercial value in the future and further expansion of talent demand.
Application of artificial intelligence in all walks of life
How does artificial intelligence solve the pain points in the industry?
Security: Use computer vision technology and big data to analyze the life track and possible places of criminal suspects.
Finance: Use speech recognition, semantic understanding and other technologies to build intelligent customer service.
Medical care: Intelligent images can quickly screen early cancer and help patients show lesions earlier.
Transportation: Unmanned driving liberates people's hands and perception through sensors, computer vision and other technologies.
Retail: Using computer vision, speech/semantic recognition, robotics and other technologies to enhance the consumer experience.
Industrial manufacturing: robots replace workers in dangerous places and efficiently complete repetitive work on the assembly line.
