[Cosmic37]: hello perly kings and queens
[jedikaiti]: 'ello Monks
[Cosmic37]: and monkeys too...
[Cosmic37]: is anyone doing machine learning with Perl?
[Cosmic37]: I was using gneural code in C and it was interesting but did not have back propagation for neural networks
[corenth]: Cosmic, poking at it, but not really.
[Cosmic37]: I read that its possible to use the FANN library with Perl so I might try that now...
[corenth]: i have a question. I used map{ blah();blah(); blah();}@stuff; and it used up a ton of memory vs. the for(@stuff){} equivalent. What gives? (if anyone knows)
[Cosmic37]: FANN also has LGPL license which I like and its supposed to be quite a capable library from what I read
[corenth]: Cosmic, that sounds interesting. What is FANN (I could search it if I weren't so lazy about it)?
