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 by Shun'ichi Amari in 1972 and by Little in 1974 based on Ernst Ising's work with Wilhelm Lenz on … See more The Ising model of a recurrent neural network as a learning memory model was first proposed by Shun'ichi Amari in 1972 and then by William A. Little in 1974, who was acknowledged by Hopfield in his 1982 paper. Networks … See more Updating one unit (node in the graph simulating the artificial neuron) in the Hopfield network is performed using the following rule: See more Hopfield nets have a scalar value associated with each state of the network, referred to as the "energy", E, of the network, where: See more Initialization of the Hopfield networks is done by setting the values of the units to the desired start pattern. Repeated updates are then performed until the network converges … See more The units in Hopfield nets are binary threshold units, i.e. the units only take on two different values for their states, and the value is determined by whether or not the unit's input exceeds its threshold $${\displaystyle U_{i}}$$. Discrete Hopfield nets … See more Bruck shed light on the behavior of a neuron in the discrete Hopfield network when proving its convergence in his paper in 1990. A subsequent paper further investigated the … See more Hopfield and Tank presented the Hopfield network application in solving the classical traveling-salesman problem in 1985. Since then, the Hopfield … See more

WebApr 4, 2024 · B idirectional Associative Memory (BAM) is a recurrent neural network (RNN) of a special type, initially proposed by Bart Kosko, in the early 1980s, attempting to overcome several known drawbacks of the auto-associative Hopfield network, and ANNs, that learn associations of data from continuous training. WebThe simulation of a continuous network in a digital computer implies the discretization of the ODE, which is usually carried out by simply substituting the derivative by the di erence, without any further theoretical justi cation. Instead, the numerical solution of the ODE is proposed. Among the existing numerical methods for ODEs, we have…
