# Hopfield network. 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 Ising Model.

work. Finally, in section 3, we consider general discrete-time delayed models that include our neural network models as particular cases and obtain the abstract global stability result that we use to prove the stability results in section 2. 2. Hopfield Models As a generalization of the continuous-time Hopﬁeld neural network models pre-

Artificial neural network models have been studied for many years with the hope of designing information processing systems solutions can be found by using a Hopfield model of neural networks. Hopfield's neural network [1] is such a model of associative content addressable memory. An important property of the Hopfield neural network is its guaranteed convergence to stable states (interpreted as the stored memories). In this work we introduce a generalization of the Hopfield model by Based on modern Hopfield networks, a method called DeepRC was designed, which consists of three parts: a sequence-embedding neural network to supply a fixed-sized sequence-representation (e.g. 1D-CNN or LSTM), a Hopfield layer part for sequence-attention, and; an output neural network and/or fully connected output layer.

The idea behind this type of algorithms is very simple. It can store useful information in memory and later it is able to reproduce this information from partially broken patterns. The Hopfield neural-network model is attractive for its simplicity and its ability to function as a massively parallel, autoassociative memory. Recurrent neural networks (of which hopfield nets are a special type) are used for several tasks in sequence learning: Sequence Prediction (Map a history of stock values to the expected value in the next timestep) Sequence classification (Map each complete audio snippet to a speaker) Sequence labelling (Map an audio snippet to the sentence spoken) Ⅳ.

### 2020-02-27 · A Hopfield network is a kind of typical feedback neural network that can be regarded as a nonlinear dynamic system. It is capable of storing information, optimizing calculations and so on. Firstly, the network is initialized to specified states, then each neuron is evolved into a steady state or fixed point according to certain rules.

Hopfield neural networks represent a new neural computational paradigm by implementing an autoassociative memory. They are recurrent or fully interconnected neural networks. A Hopfield network is a simple assembly of perceptrons that is able to overcome the XOR problem (Hopfield, 1982). The array of neurons is fully connected, although neurons do not have self-loops (Figure 6.3).
