Nope sorry - been totally snowed under the past couple of months - not had any time to work on it.
If you’re referring to the alternative cost functions for GANs I don’t think they make much difference?
If you’re referring to non Gaussian attention mechanisms for the DRAW encoder, I don’t know of any better approach than @pranav 's as mentioned above. I think he’s open sourced his code?
Cheers,
