Single-layer n-neuron Hopfield network x1 1 y1 x2 2 y2 Input Signals Output Signals xi i yi xn n yn Hopfield Neural Network The Hopfield network uses McCulloch and Pitts neurons with the sign activation function as its computing element: 1, if X 0 sign Y 1, if X Y, if X The current state of the Hopfield network is determined by the current outputs of all neurons, y1, y2, . Hopfield nets have a scalar value associated with each state of the network referred to as the "energy", E, of the network, where: This value is called the "energy" because the definition ensures that if units are randomly chosen to update their activations the network will converge to states which are local minima in the energy function (which is considered to be a Lyapunov function ). In the Hopfield network, each unit does not have a relationship with itself, thus the value of the weight matrix Hopfield models using diagonal matrix weighting of zero (0). - PROTEIN SECONDARY STRUCTURE PREDICTION WITH NEURAL NETWORKS Neural Networks Class of algorithms modelled after a biological brain Can be used for both supervised and ...

A Hopfield network (or Ising model of a neural network or Ising–Lenz–Little model) is a form of recurrent artificial neural network popularized by John Hopfield in 1982, but described earlier by Little in 1974 based on Ernst Ising's work with Wilhelm Lenz. Hopfield Network! Hopfield Network is a recurrent neural network with bipolar threshold neurons. We use Hopfield networks in a novel way by not storing a single pattern (e.g. The networks generated by Hebbian learning are usually dense, with >95% of the weights non-zero. 3.3 Network pruning .
