The goal of the present work is to investigate the role of trivial disorder and nontrivial disorder in the three-state Hopfield model under a Gaussian random field. In order to control the nontrivial disorder, the Hebb interaction is used. This provides a way to control the system frustration by means of the parameter a=p/N, varying from trivial randomness to a highly frustrated regime, in the

In this work, we introduce and investigate the properties of the “relativistic” Hopfield model endowed with temporally correlated patterns. First, we review the “relativistic” Hopfield model and we briefly describe the experimental evidence underlying correlation among patterns. Phase diagrams and the instability of the spin glass states for the diluted Hopfield neural network model. In: Journal de Physique I, 1992, vol. 2, As 0, m approaches the value (3.5) at low T . But at any > 0, m eventually peels off from this asymptote to reach m = 1 for T 0.

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.

Phase diagrams are presented for c=1, 0.1, 0.001 and c↦0, where c is the fractional connectivity. The line Tc where the memory states become global minima (having lower free energy single phase AC-AC chopper is discussed. Generalized Hopfield Neural Network (GHNN) is a continuous time single layer feedback network. Figure.1 shows the block diagram of the proposed method.

Let us compare this result with the phase diagram of the standard Hopfield model calculated in a replica symmetric approximation [5,11]. Again we have three phases. For temperatures above the broken line T SG , there exist paramagnetic solutions characterized by m = q = 0, while below the broken line, spin glass solutions, m = 0 but q = 0, exist.

The action of individual neurons is modeled as a  Jul 5, 2019 As we will see in the following section, a Hopfield Network is a form of pendulum phase diagram The circle in the diagram is called “orbit”. As an extension of the Hopfield model, we propose a neural network found to be retrievable if the temperature T is lower than 1/D. The phase diagram and the. Mar 9, 2018 weight matrix W.

Each trajectory starts at the end of a black line, and the activity moves along that line to ultimately terminate in one of the two point attractors located at the two 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. Properties of retrieval phase 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.
