randnr

Normalized row weight initialization function

Syntax

W = randnr(S,PR)


Description

randnr is a weight initialization function.

W = randnr(S,PR) takes two inputs,

S	Number of rows (neurons)
PR	R-by-2 matrix of input value ranges = [Pmin Pmax]

and returns an S-by-R random matrix with normalized rows.

You can also call this in the form randnr(S,R).

Examples

A matrix of three normalized four-element rows is generated:

M = randnr(3,4)
M =
    0.9713    0.0800   -0.1838   -0.1282
    0.8228    0.0338    0.1797    0.5381
   -0.3042   -0.5725    0.5436    0.5331
