title: What is the difference between back-propagation and feed-forward Neural Network?
body: <p>What is the difference between back-propagation and feed-forward neural networks?</p>
  
  <p>By googling and reading, I found that in feed-forward there is only forward direction, but in back-propagation once we need to do a forward-propagation and then back-propagation. I referred to <a href="http://www.nnwj.de/backpropagation.html" rel="noreferrer">this link</a></p>
  
  <ol>
  <li>Any other difference other than the direction of flow? What about the weight calculation? The outcome? </li>
  <li>Say I am implementing back-propagation, i.e. it contains forward and backward flow. So is back-propagation enough for showing feed-forward?</li>
