  --- BEGIN ISSUE ---
  Replicability in Neural networks and Random forests
  Follow up from #3715: Neural networks and Random forests should have a checkbox `Replicable training` or something like this, which would decide whether random seed is fixed (to 0) or "random".
  
  In Neural networks: add the check box.
  
  In Random forest: remove the spin box.
