title: How to choose number of hidden layers and nodes in neural network?
body: <p>What does number of hidden layers in a multilayer perceptron neural network do to the way neural network behaves? Same question for number of nodes in hidden layers?</p>
  
  <p>Let's say I want to use a neural network for hand written character recognition. In this case I put pixel colour intensity values as input nodes, and character classes as output nodes. </p>
  
  <p>How would I choose number of hidden layers and nodes to solve such problem?</p>
