midpoint

Midpoint weight initialization function

Syntax

W = midpoint(S,PR)


Description

midpoint is a weight initialization function that sets weight (row) vectors to the center of the input ranges.

W = midpoint(S,PR) takes two arguments,

S	Number of rows (neurons)
PR	R-by-Q matrix of Q input (column) vectors with values in the ranges = [Pmin Pmax] where Q is the batch size

and returns an S-by-R matrix with rows set to (Pmin+Pmax)'/2.

Examples

Here initial weight values are calculated for a five-neuron layer with input elements ranging over [0 1] and [-2 2].

W = midpoint(5,[0 1; -2 2])
