Negative sampling features #773

Open viswa-nvidia opened 3 years ago

We'd like to integrate several varieties of negative sampling into the NVT/Merlin dataloaders:

[ ] Popularity biased negatives from in-batch examples
[ ] Uniform negatives from all items
[ ] Uniform negatives from recent items (from #356)
[ ] Popular items based on recent interactions (from #356)

I think this is a duplicate of #356

Let's make this the over-arching "epic" ticket for smaller negative sampling features then.
