Minimize the error in the prediction by adjusting the weight vector 'w'.
Minimize the error in the prediction by adjusting the weight vector 'w'. The error 'e' is simply the difference between the target value 'y' and the predicted value 'z'. Mininize 1/2 of the dot product of error with itself using gradient-descent. The gradient is '-x.t * (e * z * (_1 - z))', so move in the opposite direction of the gradient.

The
Perceptronclass supports single-valued 2-layer (input and output) Neural-Networks. Given several input vectors and output values (training data), fit the weights 'w' connecting the layers, so that for a new input vector 'zi', the net can predict the output value 'zo', i.e., 'zi --> zo = f (w dot zi)'. Note, w0 is treated as the bias, so x0 must be 1.0.
