title: What is the structure of the MLP's input?
body: <p>Each complex number, component of either an input or an output pattern, is associated
  with two adjacent neurons of the MLP input or output layer respectively, having its real part assigned to the left neuron of the pair and its imaginary part to the right one.</p>
  
  <p>1) What's the meaning of "its real part assigned to the left neuron of the pair and its imaginary part to the right one"?</p>
  
  <p>2) How to handle complex number as the input of neural network , how to train? Do I still use the fully connected neural network?</p>
