6. Lecture from the course Neural Networks for Machine Learning, as taught by Geoffrey Hinton (University of Toronto) on Coursera in 2012. Link to the course (l To better understand the Hopfield model I have read several papers that investigated this model, and to better understand these papers I have tried to replicate the simulations that were performed. To make my life a little bit easier I am developing corresponding Matlab functions that help with these simulations. For \(a=2\), the classical Hopfield model (Hopfield 1982) is obtained with the storage capacity of \(C \cong 0.14d\) for retrieval of patterns with a small percentage of errors. Demircigil et al. extended the energy function by using an exponential interaction function \(F(z)=\text{exp}(z)\): Former student Sophia Day (Vanderbilt '17) graciously takes us through a homework assignment for my Human Memory class.

アメリカ合衆国の物理学者であるジョン・ホップフィールド (J.J. Hopfield) が提唱した 。 In 1982, Hopfield developed a model of neural networks to explain how memories are recalled by the brain.

Hopfield Model Hopfield (1982) proposed that memories could be energy minima of a neural net with symmetric weights – The binary threshold decision rule can take partial memory and clean them up into full memories The idea of memories as energy minima was proposed by I.A. Richards in 1924 – Memories are like a large crystal than can sit on To store fundamental memories, the Hopfield model uses the outer-product rule, a form of Hebbian learning: 𝑤𝑤 𝑗𝑗𝑗𝑗 = 1 𝑁𝑁 𝜉𝜉 𝜇𝜇,𝑗𝑗 𝑀𝑀 𝜇𝜇=1 𝜉𝜉 𝜇𝜇,𝑗𝑗 • Hence 𝑤𝑤 𝑗𝑗𝑗𝑗 = 𝑤𝑤 𝑗𝑗𝑗𝑗, i.e., 𝐰𝐰= 𝐰𝐰 𝑇𝑇, so the weight matrix is Hopfield Model by B. Lautrup, June 1990, World Scientific Pub Co Inc edition, Hardcover in English 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 σ i z is a long range two-body random interaction. The randomness in the couplings is the typical interaction of the Hopfield model with p patterns ( p < N ), where the patterns are p sequences of N independent identically distributed random Hopfield Model.

Provided is a proof of the Hamiltonian being monotonically decreasing under asynchronous network dynamics. In a Hopfield network, all the nodes are inputs to each other, and they're also outputs.
