### Hopfield neural networks have found applications in a broad range of disciplines [3-5] and have been studied both in the con-tinuous and discrete time cases by many researchers. Most neural networks can be classified as either continuous or discrete. In spite of this broad classification, there are many real-world systems and

In spite of this broad classification, there are many real-world systems and 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).This leads to K(K − 1) interconnections if there are K nodes, with a w ij weight on each.

Minnesstrategi Efter uppgift Efter dig Extern lagring 44 Baddeleys' Working Memory Model 45 Working Memory Model Fonologisk Loop akustisk repetition 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. The Hopfield model consists of a network of N binary neurons. A neuron i is characterized by its state Si = ± 1. The state variable is updated according to the dynamics defined in Eq. (17.3). The task of the network is to store and recall M different patterns. The Hopﬁeld model consists of N binary variables or bits, Si ∈ {+1,−1}.
