How detect by code which condition halted NN traning

8 views (last 30 days)
I'm using a feedforwardnet NN and I would like to know from code which condition determined NN training stop (max validation checks reached, max epoch, performance goal, etc..). Is it possible? Thanks for your replys. Regards.

[x,t] = simplefit_dataset;
net = fitnet(10);
[net tr] = train(net,x,t);
stopcriteria = tr.stop
tr = tr
stopcriteria =
Validation stop.
tr =
trainFcn: 'trainlm'

testInd: [1x14 double]
stop: 'Validation stop.'
num_epochs: 16

perf: [1x17 double]
vperf: [1x17 double]
tperf: [1x17 double]
mu: [1x17 double]

val_fail: [1x17 double]
best_perf: 1.3525e-04
best_vperf: 1.7348e-04

Hope this helps.
