title: How to calculate relative importance of predictors in neural networks
body: <p>I have to model a neural network with two inputs and one output. I have to use single hidden layer and single node in hidden layer. The question says 'For neural network model trained, compute the relative
  importance (RI) of the two predictors. You are free to use any metric to quantify the importance
  of predictors'. Can anyone help me? Thanks</p>
