NCE accuracy calculation

[JaejinCho]

Hello @jefflai108,

I think the accuracy also should have its denominator as batch*self.timestep at

Contrastive-Predictive-Coding-PyTorch/src/model/model.py

Line 320 in a9dab4e

 accuracy = 1.*correct.item()/batch 

Possibly for other models too although I did not check them.

Yes, and it should be correct += I believe, just above there...
