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. Hopfield networks serve as content-addressable ("associative") memory systems with binary threshold nodes.

A Hopfield network (or Ising model of a neural network or Ising–Lenz–Little model) is a form of recurrent artificial neural network popularized by John Hopfield in 1982, but described earlier by Little in 1974 based on Ernst Ising's work with Wilhelm Lenz.

1992-11-01 We investigate the retrieval phase diagrams of an asynchronous fully connected attractor network with non-monotonic transfer function by means of a mean-field approximation. We find for the noiseless zero-temperature case that this non-monotonic Hopfield network can store more patterns than a network with monotonic transfer function investigated by Amit et al.

Again we have three phases.

2014 The phase diagram of Little's model is determined when the number of stored patterns The retrieval region is some what larger than in Hopfield's model.

1791-1801 Abstract The replica-symmetric order parameter equations derived in [2, 4] for the symmetrically diluted Hopfield neural network model [1] are solved for different degrees of dilution. The dilution is random but symmetric. Phase diagrams are presented for c=1, 0.1, 0.001 and c↦0, where c is the fractional connectivity.

For example, consider the problem of optical character recognition. The task is to scan an input text and extract the characters out and put them in a text file in ASCII form.

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 … 1992-11-01 The phase diagrams of the model with finite patterns show that there exist annealing paths that avoid first-order transitions at least for . The same is true for the extensive case with k = 4 and 5.
