Question To distinguish between electrons and photons 

Forum: Event and Track Management

   I have a query regarding my Calorimeter which is a normal Scintillator-lead sandwiched detector. I know that to distinguish between photons and electrons the conventional way is to have two layers, an initial dE layer and a final E layer, and look at the dE vs E distributions.Could you please give me some idea/suggestion how should I implement that in my calorimeter set up? 
   On the other hand, somewhere I read or heard that the modern way to do the same is to have lots of layers and train a neural net based on the energy deposition in each.
Could you please help me in any of these issues?
