|
28 <CODE>y = mlpfwd(net, x)</CODE> takes a network data structure <CODE>net</CODE> together with
|
|
wolffd@0
|
29 a matrix <CODE>x</CODE> of input vectors, and forward propagates the inputs
|
|
wolffd@0
|
30 through the network to generate a matrix <CODE>y</CODE> of output
|
|
wolffd@0
|
31 vectors. Each row of <CODE>x</CODE> corresponds to one input vector and each
|
|
wolffd@0
|
32 row of <CODE>y</CODE> corresponds to one output vector.
|
|
wolffd@0
|
33
|
|
wolffd@0
|
34 <p><CODE>[y, z] = mlpfwd(net, x)</CODE> also generates a matrix <CODE>z</CODE> of the hidden
|
|
wolffd@0
|
35 unit activations where each row corresponds to one pattern.
|
|
wolffd@0
|
36
|
|
wolffd@0
|
37 <p><CODE>[y, z, a] = mlpfwd(net, x)</CODE> also returns a matrix <CODE>a</CODE>
|
|
wolffd@0
|
38 giving the summed inputs to each output unit, where each row
|
|
wolffd@0
|
39 corresponds to one pattern.
