Re: NNP - Neural Networks with Perl

Hi,

That was quick, I only uploaded NNFlex a few days ago! To answer your question, it was written because I couldn't get the other NN backprop perl modules to work, so thats my experience with NN in perl. It isn't especially quick yet though, if you have a requirement for fast learning, you might be better with one of the interface modules like AI-jneural, although obviously I'd love people to use NNFlex and provide feedback!

Alternatively, if you're running unix, with a bit of hacking around you can control xerion with a pair of FIFO's and open them in perl as filehandles. Xerion is available from http://www.cs.toronto.edu/~xerion/ - if you want help with that or with NNFlex, post a message for me on perl-ai.

1st, NNFlex works very well, specially because we can set the number of layers, nodes and extra configurations for each layer, what make possible to use NNFlex in many different problems. I have rewrited your modules to fix some load and save (dump_state/load_state). Now I'm able to serialize the NN and load it with 100% of the previous state. Also the code is faster. Then I have added a new interface where is very easy to learn a set and get the output with the same values of the inputs. I will send the code to you in sime days.	[reply]
