Perceptron learning Apash Roy, CSA, University of North Bengal
Perceptron learning w ij (new) = w ij (old) + c(d i - y i )x i where, w ij : the connection weight from i th input element x i of X to the j th neuron of the network. d i and y i :the desired and actual output of j th neuron. c :the small positive constant representing the learning rate.
