twitter-team b85210863f [home/recap] Update heavy ranker explanation of weighted engagement probabilities
Update heavy ranker README with:
- Clarification that engagement probability weights aren't hardcoded in the code.
- Explanation of how the engagement probability weights were obtained.

This project open sources some of the ML models used at Twitter.

Currently these are:

  1. The "For You" Heavy Ranker (projects/home/recap).

  2. TwHIN embeddings (projects/twhin) https://arxiv.org/abs/2202.05387

This project can be run inside a python virtualenv. We have only tried this on Linux machines and because we use torchrec it works best with an Nvidia GPU. To setup run

./images/init_venv.sh (Linux only).

The READMEs of each project contain instructions about how to run each project.
