== FANN: Fast Artificial Neural Network Library ==

From the [http://fann.sf.net FANN website]:

''Fast Artificial Neural Network Library is a free open source neural network library, which implements multilayer artificial neural networks in C with support for both fully connected and sparsely connected networks. Cross-platform execution in both fixed and floating point are supported. It includes a framework for easy handling of training data sets. It is easy to use, versatile, well documented, and fast. PHP, C++, .NET, Ada, Python, Delphi, Octave, Ruby, Prolog Pure Data and Mathematica bindings are available. A reference manual accompanies the library with examples and recommendations on how to use the library. A graphical user interface is also available for the library.''

The Matlab Neural Network toolbox is a great piece of software but unfortunately much too slow. Therefore I decided to add the FANN library as an optional backend. Unfortunately there were no Matlab bindings available so I quickly hacked some together. I'm putting them online in the hope somebody will pick them up and improve/extend them (since they are pretty basic).

== Installation ==

Version of the FANN library required: 2.1beta

Enclosed is a GNU makefile that builds the mex files (you may have to edit the makefile a little to accommodate for your environment). If anybody is willing to contribute windows binaries or Makefiles please do!

Make sure the mex files are in your Matlab path and Matlab knows where to find the FANN library (e.g., see LD_LIBRARY_PATH on unix systems).

== Usage ==

* Create a network
<code><pre>ann = createFann([2 5 3 1],connectivity)</pre></code>
* Train a network
<code><pre>ann = trainFann(ann,samples,values,[desired error],[max epochs])</pre></code>
* Use a network
<code><pre>values = testFann(ann,samples)</pre></code>

Where samples are the input data points and values the output values, both in column format (1 column per dimension).

'''Note: do not use a connectivity different from 1 for else you will get wrong results''' (I hope this can be fixed with the new fann library)

== Contribute ==

These bindings are very basic but they work for me. Please improve, extend, provide binaries, and of course contribute back.
