Development history table.

Stage	History of development
The first stage is the mid-1950s	Inspired by neurophysiology and biology, he mainly studies neural network system
The second stage is the early 1960s	Enlightened by psychology and human learning, it mainly obtains conceptual learning and language
The third stage is the middle and late 1970s	On the one hand, a large number of domain knowledge is introduced into the learning program; on the other hand, knowledge is acquired automatically
The fourth stage is the middle and late 1980s	Neural networks are emerging again, and multilayer neural networks and backpropagation algorithms are proposed to overcome the limitations of the early days
