Hey David,

Disclaimer: I am far from an expert.

I noticed that in your implementation of CPC your datasets can provide a variable number of positive samples. Scaling with your batch size in your case.

In the original paper, I think the authors intend NCE to be used with only one positive sample.

I wonder if this might affect the outcome.
Certainly it must affect the guarantees made by the paper for having a bound on the mutual information. (?)
