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 = M1/100)

`W`	`S` x `R` weight matrix
`B`	`S` x `1` bias vector
`maxw`	Maximum weight (default = `max(max(abs(W)))`)
`minw`	Minimum weight (default = M1/100)

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)
