Hopfield control

WebThe modified Hopfield neural network is used for solving TSP problem, and the experimental results show that the network will escape the local minimum. The validity and feasibility of the modified Hopfield neural network is proved. Published in: 2016 12th World Congress on Intelligent Control and Automation (WCICA) Article #: WebThe storage capacity of a Hopfield net • Using Hopfield’s storage rule the capacity of a totally connected net with N units is only about 0.15N memories. – At N bits per memory this is only bits. – This does not make efficient use of the bits required to store the weights. • The net has weights and biases.

The problems to be solved must be formulated in terms of desired optima, often subject to constraints. The general principles involved in constructing networks to solve specific problems are discussed.
