Plotperformance of several neural networks

Hi. I want to compare performance of neural network depending on training algorithm.

[net,tr] = train(net,inputs,targets,inputStates,layerStates);
[net1,tr1] = train(net1,inputs,targets,inputStates,layerStates);

Now the problem is that when I do

plotperform(tr,tr1)       %%first variant
plotperform(tr,t,tr1,t)   %%sendond variant

I get errors. If I do

plot(tr.perf,t,tr1.perf,t)

I get plots that are very undetalized, they almost look like straight lines. So my question is is it possible to use plotperf function to plot several neural nets at a time? or at least how to increase detalization of plot function, because it simplifies performance curve too much compared to plotperf.

plotperform only takes one tr as input.

You can use plot. However, you have to provide the details yourself.

To plot multiple curves you have to provide input and output for each curve

 plot(x1,y1,x2,y2,... )

Hope this helps.

Is it possible to increase detalization of plot? no matter how i zoom it, figures are significantly less detalized compared to plotperform

[Greg Heath]

Yes, it is. However, I cannot help with that. Your best bet is to look at the source code via

 type plotperform
