Hopfield Network (霍普菲尔德网络),是 Hopfield 在1982年提出的一种基于能量的模型,发表的文章是 Neural networks and physical systems with emergent collective computational abilities。基本结构如下图所示:
首先我们来看Hopfield Network的一句话定义:
Hopfield Network is a model that can reconstruct data after being fed with corrupt versions of the same data.
也就是说利用Hopfield Network的过程是:
\[some\ data\ →\ Hopfield\ Network\ →\ full\ data \]
