Hopfield network easy explanation
WebA classic "Hopfield network" is a type of artificial neural network in which the units are bi-stable and fully interconnected by symmetrically weighted connections. In 1982, Hopfield showed that such networks are characterized by an "energy function", under which stored memories correspond to local energy minima [1]. Web霍普菲爾德神經網絡(Hopfield neural network)是一種循環神經網絡，由約翰·霍普菲爾德在1982年發明。 Hopfield網絡是一種結合存儲系統和二元系統的神經網絡。 它保證了向局部極小的收斂，但收斂到錯誤的局部極小值（local minimum），而非全局極小（global minimum）的情況也可能發生。

WebBest known are Hopfield Networks, presented by John Hopfield in 1982. As the name suggests, the main purpose of associative memory networks is to associate an input with its most similar pattern. In other words, the purpose is to store and retrieve patterns. We start with a review of classical Hopfield Networks. Hopfield Networks WebHopfield networks are recurrent neural networks with dynamical trajectories converging to fixed point attractor states and described by an energy function. The state of each model …

In this sense,... WebOne kind of arti cial network proposed by John J. Hop eld in 1982 has been among the more successful ones, and is still in active use today. It has been suggested that in addition to its merits in machine learning, it could also serve as a foundation of the explanation of human ability of recollection and association.
