5、w Hampshire.The study is to proceed on the basis of the conjecture that every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.An attempt will be made to find how to make machines use language,form abstractio

6、ns and concepts,solve kinds of problems now reserved for humans,and improve themselves.We think that a significant advance can be made in one or more of these problems if a carefully selected group of scientists work on it together for a summer.”(McCarthy,John;Minsky,Marvin;Rochester,Nathan;Shannon,Claude(1955),A Proposal for the Dartmouth Summer Research Project on Artificial Intelligence)人工智能还缺少：小数据的学习能力自主地探索环境通过和人的交流学习
