Neuronal Net training

I've been training a network. how can I get the output all 20 epochs?

I want to show the progress of teach an image.

I do not know how you would get the outputs, sorry.

I do recall Greg Heath pointing out that when you get the training outputs, it can be fairly tricky to interpret them, with the difficulty depending on the kind of net and the number of layers. My recollection is that he has some code for helping to visualize the output matrices.

Which network?

Which outputs?

help train

doc train

Look at the explanation of what outputs are available at the END of training; e.g.,

[net tr Y E Pf Af ] = train(net,p,t,Pi,Ai );

The only information on what happened DURING training is in the structure tr and the command line output. Try

net.trainParam.show= 1;

If you want to obtain a complete history of [net ... Ai], try removing the semicolon.

WARNING: If you try to obtain a history by looping over a succession of 1 epoch training calls, you can get a valid result. HOWEVER, you will not get the same result as that from a single multi-epoch call.

Hope this helps.
