title: python neurolab feed forward neural network
body: <p>Could anyone explain to me how to use this library:</p>
  
  <p><a href="http://code.google.com/p/neurolab/" rel="nofollow">http://code.google.com/p/neurolab/</a></p>
  
  <p>to create a Neural Network that follows these rules:</p>
  
  <ol>
  <li><p>Feed forward multilayer:<code>3 layers, 225 inputs, 50 hidden and 10 output</code> </p>
  
  <p>(because input is 15x15 black/white image, ouput is 10 digits)</p></li>
  <li><p>Back error propagation</p></li>
  </ol>
  
  <p>I have problem with installing PyBrain on OSX, maybe in this will be easier.</p>
