Hey Filippo,

I think that should be possible.  If I am understanding right you would
just need to implement a new loss layer and its gradient.  Take a look
at NegativeLogLikelihood<> and other loss layers in
src/mlpack/methods/ann/layer/loss_functions/ for an example; I think you
can adapt some of those.

Hope this helps!

Thanks,

Ryan
