《认知科学中神经网络理论与应用基础研究》是我国863攀登计划中一个重大关键项目,何振亚教授是该项目首席科学家。1996年12月经国家科委专家组评审,该项目总体水平“优”,达到国际先进水平。为向有志于从事此项研究的青年科技工作者和青年学生介绍神经网络的现状和发展,特约何振亚教授撰写此文。本刊时何先生热忱普及科学研究成果致以衷心感谢。 The “Research on the Theory and Application of Neural Network in Cognitive Science” is a major key project in China’s 863 climbing plan. Professor He Zhenya is the chief scientist of the project. In December 1996, it was reviewed by the expert group of the State Science and Technology Commission. The overall level of the project was “excellent” and reached the international advanced level. In order to introduce the current status and development of neural networks to young scientists and young students who are interested in this research, special expert Professor He Zhenya wrote this article. Mr. He was very grateful for the popularity of scientific research results.
