Implementation of Dropout

I would like to use Dropout with SameDiff.

public DropOut(SameDiff sameDiff, SDVariable input, double p) {
    super(sameDiff, input);
    this.p = p;
    throw new UnsupportedOperationException("Dropout SameDiff support disabled pending backprop support");

is closed.
Can I have any crue to implemnt this part on my own?
