Hi,

Is there a way to add another loss function and modify the RNNLM Architecture so that the RNNLM is trained for domain classification also? And so that it produces a domain label as additional output that I can integrate into the Kaldi RNNLM Rescoring Framework? I think I can do the latter part, i.e., fusing it into the Lattice Rescoring, but am not sure about how to do the first.

How do I modify the architecture and add the Additional Loss?


Thanks
Roshan S. Sharma

Sorry, that wouldn't be possible without rather complex code changes -- or at least, lots of C++-level code changes :-(
