Examples

collapse all

This example shows how to plot the histogram of error values of a trained feed-forward network.

Create a feed-forward network and train it using the data from the simple fit data set. Then plot the histogram of error values.

[x,t] = simplefit_dataset;
net = feedforwardnet(20);
net = train(net,x,t);
y = net(x);
e = t - y;
ploterrhist(e,'bins',30)

Histogram of error values. The errors are clustered around zero in a roughly Gaussian distribution.

Input Arguments

collapse all

Errors to plot, specified as a vector or a matrix.

Number of bins to use in the histogram plot, specified as the comma-separated pair consisting of 'bins' and an integer.
