The randomness in the couplings is the typical interaction of the Hopfield model with p patterns (p< 2017-10-10 · Here we employ quantum algorithms for the Hopfield network, which can be used for pattern recognition, reconstruction, and optimization as a realization of a content-addressable memory system. We show that an exponentially large network can be stored in a polynomial number of quantum bits by encoding the network into the amplitudes of quantum states. 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. Quantum neural networks are computational neural network models which are based on the principles of quantum mechanics. The first ideas on quantum neural computation were published independently in 1995 by Subhash Kak and Ron Chrisley, engaging with the theory of quantum mind, which posits that quantum effects play a role in cognitive function. Finally, we express the Hopfield model, a general description based on the quantization of a linear dielectric medium, in a manifestly gauge-invariant form, and show that the Dicke model in the dilute regime can be regarded as a particular case of the more general Hopfield model.

Als Hopfield-Netz bezeichnet man eine besondere Form eines künstlichen neuronalen Netzes. Es ist nach dem amerikanischen Wissenschaftler John Hopfield benannt, der das Modell 1982 bekannt machte. Inhaltsverzeichnis
Motivated by recent progress in using restricted Boltzmann machines as preprocessing algorithms for deep neural network, we revisit the mean-field equations [belief-propagation and Thouless-Anderson Palmer (TAP) equations] in the best understood of such machines, namely the Hopfield model of neural networks, and we explicit how they can be used as iterative message-passing algorithms

The quantum model of the brain proposed by Ricciardi and Umezawa is extended to dissipative dynamics in order to study the problem of memory capacity. It is shown that infinitely many vacua are accessible to memory printing in a way that in sequential information recording the storage of a new information does not destroy the previously stored ones, thus allowing a huge memory capacity. 2021-04-09

Hopfield’s classical neural networks [1] have been intensely investigated and modeled for cognitive neurosciences [2]. It has been recently shown that Feynman’s propagator version of quantum theory is analogous to Hopfield’s model of classical associative neural network [3] - which is outlined in the first part of
Quantum Hopfield network Consider a model with rank-pmatrix of interactions and no longitudinal field (hi=0):ref.31 (cf.rk Jik=Nfor SK model), where are taken to be independent and identically distributed (i.i.d.) random variables of unit variance. The coupling among the sigma_i^z is a long range two bodies random interaction. To practically illustrate this, we consider a simple textbook problem, namely the k

Thus, similar to the human brain, the Hopfield model has stability in pattern recognition. A Hopfield network is a single-layered and recurrent network in which the neurons are entirely connected, i.e., each neuron is associated with other neurons. In particular, we developed an open-system quantum generalisation of the celebrated Hopfield neural network, a simple toy model of associative memory, which allowed us to treat thermal and quantum coherent effects on the same footing. 2018-06-13

In this Letter we show that a close analogue of this behavior can occur in the real time evolution of quantum systems, namely nonanalytic behavior at a critical time. We denote such behavior a dynamical phase transition and explore its properties in the transverse-field Ising model. Quantum Associative Memory (QuAM) - a quantum variant of Associative Memory - employs a quantum system as a storage medium and two quantum algorithms for information storage and retrieval. One of the milestones for the current renaissance in the field of neural networks was the associative model proposed by Hopfield at the

Hopfield neural network was invented by Dr. John J. Hopfield in 1982. It consists of a single layer which contains one or more fully connected recurrent neurons. However, we still don't have a simple lattice Hamiltonian describing the quantum Hall effect - we'd like to have something like the Kitaev chain model, which was

a number of theories of consciousness in existence, some of which are based on classical physics while some others require the use of quantum concepts. A Hopfield network is a single-layered and recurrent network in which the neurons are entirely connected, i.e., each neuron is associated with other neurons. It would be ideal either for courses on relativistic quantum field theory or for courses on the Standard Model of elementary particle interactions. The book provides interesting insights and covers many modern topics not usually presented in current texts such as spinor-helicity methods and on-shell recursion relations, heavy quark effective theory and soft-collinear effective field theory.Proposed by John Hopfield in 1982, the Hopfield network is a recurrent content-addressable memory that has binary threshold nodes which are supposed to yield a local minimum. It is a fully autoassociative architecture with symmetric weights without any self-loop.

Our goal with this paper is to elucidate the close connection between Hopfield networks and adiabatic quantum computing. Focusing on their use in problem solving, we point out that the energy functions minimized by Hopfield networks are essentially identical to those minimized by adiabatic quantum computers. To practically illustrate this, we consider a simple textbook problem, namely the k
