High level question about discriminator

[Marin (Michael) Moran]

Hello, I don't have a pure math background and I've tried to make my own naive implemenation of DIM where the "discriminator" is just a standard binary crossentropy sigmoid classifier where there is a 50% chance the input is global and and + example and a 50% chance the input is a global and - sample. Is this vanilla classification scheme a correct implementation of the project?

[R Devon Hjelm]

Yeh, it's just binary classification between pairs (global, local that comes from same image that produced global) and (global, local that comes from probably different image that that that produced global).
