Hi,
How to plot MSE for train and test data? (need no curve for validation)Just want a comparison of these two.
Should the MSE curves for train and test meet eachother at some epoch or should they have many points in common to could say the networks is doing well?
Thanks

close all, clear all, clc, plt=0;
[x,t] = simplefit_dataset;
net = fitnet(10);
rng(0)
[net tr ] = train(net, x, t);
plt = plt+1, figure(plt), hold on;
plot(log(tr.perf),'b', 'LineWidth', 2)
% plot(log(tr.vperf),'g', 'LineWidth', 2)
plot(log(tr.tperf),'r', 'LineWidth', 2)
Thank you for formally accepting my answer
Greg
