Repo for the recommendation engine that was part of the DRP project

Recommender Pipeline

Steps to implement a recommender pipeline (Specific implementation of this pipeline is available in ./recommender/recommender_pipeline.py)

  1. Generate reaction features

    • Get the chemicals in a reaction. For DRP these are referred to as triples
    • Generate descriptors for each of the chemicals in the reaction
    • Generate a sampling grid of reaction parameters
    • Expand grid by associating descriptors with each point on the grid
  2. Run trained models with the reaction Sieve

    • Get a trained machine learning model
    • Filter sampling grid by running it through the ML model
    • Make a list of all the potentially successful reactions as predicted by the ML model
  3. Recommend reactions

    • Calculate the mutual information of the potential reactions as compared to the already completed reactions
    • Select the top 'k' reactions with the highest MI

Progress

  • [x] Generate Reaction features
  • [x] Reaction Sieve
  • [x] Reaction Recommender
  • [ ] Test and evaluate against Nature paper
