J. Hopfield, who is a physical scientist of USA, are very instructive. At first, he wrote two papers which is published in PNAS in 1982 and 1984 respectively and a discrete model was proposed. And then, cooperating with D. W. Tank, a new continuous model was proposed. This kind of network is a feedback one. Every neurons outputs go back to act as the inputs of other neurons.

Hopfield的工作是非常有意义的，他分别在1982年和1984年，在美国PNAS杂志上提出了离散网络模型的概念，然后又与Tank合作于1985年提出了一种连续的网络模型，这种网络模型是一种自反馈的神经网络结构，每个神经元的输出都有反馈，作为其它神经元的输入。
