title: Simple multi layer neural network implementation
body: <p>some time ago I have started my adventure with machine learning (during last 2 years of my studies). I have read a lot of books and written a lot of code with machine learning algorithms EXCEPT neural networks, which were out of my scope. I'm very interested in this topic, but I have a huge problem:
  All the books I have read have two main issues: </p>
  
  <ol>
  <li>Contain tones of maths equations. After lecture I'm quite familiar with them and by hand, on the paper I can do the calculations. </li>
  <li>Contain big examples embedded in some complicated context (for example investigating internet shop sales rates) and to get inside neural networks implementation, I have to write lot of code to reproduce the context.
  What is missing - SIMPLE straightforward implementation without a lot of context and equations.</li>
  </ol>
  
  <p>Could you please advise me, where I can find SIMPLE implementation of multi layer perception (neural network) ? I don't need theoretical knowledge, and don want also context-embedded examples. I prefer some scripting languages to save time and effort - 99% of my previous works were done in Python.</p>
  
  <p>Here is the list of books I have read before (and not found what I wanted):</p>
  
  <ol>
  <li>Machine learning in action</li>
  <li>Programming Collective Intelligence</li>
  <li>Machine Learning: An Algorithmic Perspective</li>
  <li>Introduction to neural networks in Java</li>
  <li>Introduction to neural networks in C#</li>
  </ol>
