Speeding things up I know this is a rather late addition to this topic, but I've been doing a lot of work on nnflex since it was first posted on CPAN at the beginning of Jan: gmpassos, if you're still working on this you might want to think about implementing a momentum term in backprop. My experiments with XOR suggest an improvement in learning speed (measured in the number of passes) of up to 5 fold, and improved network stability (because your network is less likely to get stuck in local minima). You can get the code from the momentum.pm module in nnflex. I hope thats useful. c
