mlpfwd

Purpose

Forward propagation through 2-layer network.

Synopsis 

y = mlpfwd(net, x)
[y, z] = mlpfwd(net, x)
[y, z, a] = mlpfwd(net, x)

Description

y = mlpfwd(net, x) takes a network data structure net together with a matrix x of input vectors, and forward propagates the inputs through the network to generate a matrix y of output vectors. Each row of x corresponds to one input vector and each row of y corresponds to one output vector.

[y, z] = mlpfwd(net, x) also generates a matrix z of the hidden unit activations where each row corresponds to one pattern.

[y, z, a] = mlpfwd(net, x) also returns a matrix a giving the summed inputs to each output unit, where each row corresponds to one pattern.
