Hi, in all of the examples for mlpprocess the function takes three parameters, e.g.
y = xalglib.mlpprocess(network, x, y)

(taken from http://www.alglib.net/translator/man/manual.cpython.html#example_nn_cls2)
Why is y an input parameter? I want to make sure that I am not completely misunderstanding mlpprocess - since it evaluate a neural network with an input, the output should NOT be required. If you don't include y, python complains about the need for 3 input parameters (haven't tried in other languages)

thanks :)
