5、roceed 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 abstractions and concepts,solve kinds o

6、f 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
