Purpose

Hinton graph of weight matrix and bias vector

Syntax

• hintonwb(W,B,maxw,minw)
  

Description

hintonwb(W,B,maxw,minw) takes these inputs,

W	S x R weight matrix
B	S x 1 bias vector
maxw	Maximum weight (default = max(max(abs(W))))
minw	Minimum weight (default = maxw/100)

and displays a weight matrix and a bias vector 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. The weights are shown on the left.

Examples

The following code produces the result shown below.

• W = rands(4,5);
  b = rands(4,1);
  hintonwb(W,b)
