AI::NNEasy - Define, learn and use easy Neural Networks of different types using a portable code in Perl and XS.

=> DESCRIPTION

The main purpose of this module is to create easy Neural Networks with Perl.

The module was designed to can be extended to multiple network types, learning algorithms and activation functions.
This architecture was 1st based in the module L<AI::NNFlex>, than I have rewrited it to fix some
serialization bugs, and have otimized the code and added some XS functions to get speed
in the learning process. Finally I have added an intuitive inteface to create and use the NN,
and added a winner algorithm to the output.

I have writed this module because after test different NN module on Perl I can't find
one that is portable through Linux and Windows, easy to use and the most important,
one that really works in a reall problem.

With this module you don't need to learn much about NN to be able to construct one, you just
define the construction of the NN, learn your set of inputs, and use it.

=> USAGE

lib/AI/NNEasy.hploo  view on Meta::CPAN

  0 0 => 0 # false
  0 1 => 1 # or
  1 0 => 1 # or
  1 1 => 1 # true

Actually this is not the real explanation, but is the easiest way to understand that
you need to have a number of nodes/neuros in the hidden layer that can give the
right output for your problem.

Other inportant step of a NN is the learning fase. Where we get a set of inputs
and paste them through the NN until we have the right output. This process basically
will adjust the nodes I<weights> until we have an output near the real output that we want.

Other important concept is that the inputs and outputs in the NN should be from 0 to 1.
So, you can define sets like:

  0 0      => 0
  0 0.5    => 0.5
  0.5 0.5  => 1
  1 0.5    => 0
  1 1      => 1
