Hopfield networks and learning
WebThe Hopfield network (Hopfield 1982; Hopfield 1984) demonstrates how the mathematical simplification of a neuron can allow the analysis of the behaviour of large scale neural networks. By characterizing mathematically the effect of changes to the activation of individual units on a property of the entire neural architecture called WebThere are two types of associative memory, auto-associative and hetero-associative. BAM is hetero-associative, meaning given a pattern it can return another pattern which is potentially of a different size. It is similar to the Hopfield network in that they are both forms of associative memory.

A Hopfield network (or Ising model of a neural network or Ising–Lenz–Little model) is a form of recurrent artificial neural network and a type of spin glass system popularised by John Hopfield in 1982 as described by Shun'ichi Amari in 1972 and by Little in 1974 based on Ernst Ising's work with Wilhelm Lenz … Meer weergeven The Ising model of a recurrent neural network as a learning memory model was first proposed by Shun'ichi Amari in 1972 and then by William A. Little in 1974, who was acknowledged by Hopfield in his 1982 paper. … Meer weergeven Bruck shed light on the behavior of a neuron in the discrete Hopfield network when proving its convergence in his paper in 1990.
