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 earlier by Little in 1974 based on Ernst Ising 's work with Wilhelm Lenz on the Ising Model.

according to the Hebbian learning rule (11.6), and which is described by the Hamiltonian (11.7) is used to be called the Hopfield model of neural networks [26 ] 

The assignment involves working with The Hopfield model is a canonical Ising computing model. Previous studies have analyzed the effect of a few nonlinear functions (e.g.

The Hopfield model , consists of a network of N N neurons, labeled by a lower index i i, with 1 ≤ i ≤ N 1\leq i\leq N. Similar to some earlier models ( 335 ; 304 ; 549 ) , neurons in the Hopfield model have only two states.

To make the exercise more visual, we use 2D patterns (N by N ndarrays).

Started in any initial state, the state of the system evolves to a final state that is a (local) minimum of the Lyapunov function. There are two popular forms of the model: The Hopfield model accounts for associative memory through the incorporation of memory vectors and is commonly used for pattern classification. The purpose of a Hopfield net is to store 1 or more patterns and to recall the full patterns based on partial input. For example, consider the problem of optical character recognition.

Hopfield) が提唱した 。 In 1982, Hopfield developed a model of neural networks to explain how memories are recalled by the brain. The Hopfield model explains how systems of neurons interact to produce stable memories and, further, how neuronal systems apply simple processes to complete whole memories based on partial information.
