Hopfield energy example

WebThe energy of an N×N-neuron Hopfield neural network is defined as (10.20)E=-∑i=1N2∑j=1N2wijxi(t)xj(t)-∑i=1N2bixi(t) wijare the weights, and xiis the state of the ith neuron. bidescribes the bias input to the ith neuron. The energy of a stable Hopfield neural network is decreasing over time. WebThe energy function of interest for Hopfield networks and which we have been using to this point is: H = - 1/2 ij w ij a i a j To see that the stored patterns will be low points in the …
