Hopfield Networks (with some illustrations borrowed from Kevin Gurney's notes, and some descriptions borrowed from "Neural networks and physical systems with emergent collective computational abilities" by John Hopfield) The purpose of a Hopfield net is to store 1 or more patterns and to recall the full patterns based on partial input. 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. Get the Sample@ https://www.alliedmarketresearch.com/request-sample/2326 Neural network is a form of artificial intelligence, which involves a series of algorithms used to understand the relationship between datasets and to obtain desired output. Each attractor represents a different data value that is stored in the network, and a range of associated patterns can be used to retrieve the data pattern.

It does this by creating an energy surface which has attractors representing each of the patterns. Hopfield nets have a scalar value associated with each state of the network referred to as the "energy", E, of the network, where: This value is called the "energy" because the definition ensures that if units are randomly chosen to update their activations the network will converge to states which are local minima in the energy function (which is considered to be a Lyapunov function ).
