Purpose

Hinton graph of weight matrix

Syntax

• hintonw(W,maxw,minw)
  

Description

hintonw(W,maxw,minw) takes these inputs,

W	S x R weight matrix
maxw	Maximum weight (default = max(max(abs(W))))
minw	Minimum weight (default = maxw/100)

and displays a weight matrix represented as a grid of squares.

Each square's area represents a weight's magnitude. Each square's projection (color) represents a weight's sign: inset (red) for negative weights, projecting (green) for positive.

Examples

• W = rands(4,5);
  

The following code displays the matrix graphically.

• hintonw(W)
