In 1943, artificial neural network and mathematical model had been built which open the era of artificial neural network study.

In 1950, computer and artificial intelligence could bring prosper, Turing established “Can Machine Think?”, and came up with “Turing Test”.

In 1956, Dartmouth Conference had been launched which marked the emerge of artificial intelligence; during the conference, the tide of international academic artificial intelligence study had been risen, and Russell’s “Principia Mathematica” had been completely proved. Academic communication was being frequent at that time.

In 1969, Connectionism and Symbolicism were all in depression, Four Predictions were hard to achieve. With the limitation of calculation ability, the confidence of the country and people were weakened constantly.

BP Algorithm started to be studied, and the fifth-generation computer began to be created. The study and application of expert system was developed difficultly. With the enhancement of semiconductor technology and the cost and computing power of computer, artificial intelligence gradually started to breakthrough.

BP Network was created, and neural network had wide known, also the algorithm based on artificial neural network had a extreme boost; meanwhile, computer hardware had a rapid development; with internet created, distributed network reduced the cost of artificial intelligence.

In 2006, Deep Learning was put forward, artificial intelligence gained another ground-breaking development.

In 2010, with mobile internet’s development, the application scenarios of artificial intelligence started to increase.

In 2012, Deep Learning Algorithm obtained a breakthrough on phonetic recognition and Visual Identity. Meanwhile, with the enhancement of financing scale, artificial intelligence commercialize developed rapidly.
