Hi @jerry-rubikloud !
I think that we need to implement 2 components:
- BPRSampler. It will generate pairs from source data and put them into batch. Example: for N pairs we will have a batch with N*2 samples (
2 * i-th are winners,2 * i + 1-th are losers) - BRPLoss. It will take expanded batch output ([2*N, 1]), convert it to pairs ([N, 2]) and calculate resulting loss.
This design seems to be easy for implementation and allows to keep FM core routine unchanged
from tffm.
