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 Se hela listan på tutorialspoint.com Shcherbina, Masha; Tirozzi, Brunello; Tassi, Camillo (2020).

2021-04-09 The Hopfield model in a transverse field is investigated in order to clarify how quantum fluctuations affect the macroscopic behavior of neural networks. 2020-02-27 · Quantum Hopfield neural network We now extend the Hopfield network into a quantum regime that is designed in combination with quantum computing theory. In this network, the neurons are two-state quantum bits. Similar to a classical Hopfield network, the quantum neurons are fully connected to each other, meanwhile, a self-loop is forbidden.

Similar to a classical Hopfield network, the quantum neurons are fully connected to each other, meanwhile, a self-loop is forbidden. We find the free-energy in the thermodynamic limit of a one-dimensional XY model associated to a system of N qubits. The coupling among the is a long range two-body random interaction. The randomness in the couplings is the typical interaction of the Hopfield model with p patterns ( The Hopfield model in a transverse field is investigated in order to clarify how quantum fluctuations affect the macroscopic behavior of neural networks. Quantum computing allows for the potential of significant advancements in both the speed and the capacity of widely used machine learning techniques. 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. Hopfield dielectric – in quantum mechanics a model of dielectric consisting of quantum harmonic oscillators interacting with the modes of the quantum electromagnetic field.

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] - … 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.

The Hopfield model exhibits different behaviors depending on the number of embedded memory patterns. It has been theoretically proven by both the Hopfield neural network model and the quantum stochastic walk modelSchuld2014 (), that the walk always fully evolves to the sink state closest to the initial state in terms of the Hamming Distance, and if there are two sink states of an equal Hamming Distance to the initial state, the walk will end up with equal probabilities at the two sink states. With the increasing crossover between quantum information and machine learning, quantum simulation of neural networks has drawn unprecedentedly strong attention, especially for the simulation of associative memory in Hopfield neural networks due to their wide applications and relatively simple structures that allow easier mapping to the quantum regime. the model converges to a stable state and that two kinds of learning rules can be used to find appropriate network weights.
