plotes

Plot error surface of single-input neuron

Syntax

plotes(WV,BV,ES,V)

Description

plotes(WV,BV,ES,V) takes these arguments,

WV

1-by-N row vector of values of W

BV

1-by-M row vector of values of B

ES

M-by-N matrix of error vectors

V

View (default = [-37.5, 30])

and plots the error surface with a contour underneath.

Calculate the error surface ES with errsurf.

Examples

Plot Error Surface of Single-Input Neuron

p = [3 2];
t = [0.4 0.8];
wv = -4:0.4:4;
bv = wv;
ES = errsurf(p,t,wv,bv,'logsig');
plotes(wv,bv,ES,[60 30])

Figure contains 2 axes objects. Axes object 1 with title Error Surface, xlabel Weight W, ylabel Bias B contains 2 objects of type surface. Axes object 2 with title Error Contour, xlabel Weight W, ylabel Bias B contains 2 objects of type surface, contour.
