It has a wide range of applications in artificial intelligence, such as machine learning, associative memory, pattern Hopfield neural network (a little bit of theory) In ANN theory, in most simple case (when threshold functions is equal to one) the Hopfield model is described as a one-dimensional system of N neurons – spins ( s i = ± 1, i = 1,2,…, N ) that can be oriented along or against the local field. A Hopfield network consists of these neurons linked together without directionality. In hierarchical neural nets, the network has a directional flow of information (e.g. in Facebook’s facial •Hopfield is a recurrent network •The Hopfield model has two stages: storage and retrieval •The weights are calculated based on the stored states and the weights are not updated during iterations •Hopfield networks store states with minimum energy •One of their applications is image recognition Tarek A. Tutunji biological neural network and the Hopfield networks as models plays a very important role for actual human learning where the sequence of items learned is also included (Hopfield, 1982). The Hopfield network resonates with the emphasis of Chomsky on the role of word A Hopfield network consists of these neurons linked together without directionality. In hierarchical neural nets, the network has a directional flow of information (e.g. in Facebook’s facial Hopfield neural network (a little bit of theory) In ANN theory, in most simple case (when threshold functions is equal to one) the Hopfield model is described as a one-dimensional system of N neurons – spins ( s i = ± 1, i = 1,2,…, N ) that can be oriented along or against the local field.

Jan 10, 2017 Recurrent neural networks (RNN) have traditionally been of great interest for their capacity to store memories. In past years, several works have Abstract. One of the milestones for the current renaissance in the field of neural networks was the associative model proposed by Hopfield at the beginning of the The Hopfield network is a well-known model of memory and collective processing in networks of abstract neurons, but it has been dismissed for use in signal 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 Andrea Loettgers. Abstract-Neural network models make extensive use of the Hopfield model, the different modeling practices related to theoretical physics Hopfield Network is a recurrent neural network with bipolar threshold neurons.

Hopfield Network: Hopfield network is a special kind of recurrent neural networks that can be used as associative memory.

Hopfield Network is a recurrent neural network with bipolar threshold neurons. Hopﬁeld network consists of a set of interconnected neurons which update their activation values asynchronously. The activation values are binary, usually {-1,1}. The update of a unit depends on the other units of the network and on itself.

(with some illustrations borrowed from Kevin Gurney's notes, and some descriptions borrowed from "Neural networks and physical systems with emergent collective computational abilities" by John Hopfield) The purpose of a Hopfield net is to store 1 or more patterns and to recall the full patterns based on partial input.
