Problem 53

  • Title: CASF: Comparative assessment of scoring functions for protein-ligand docking problem
  • Problem: We have to create a scoring model^ which predicts will the couple protein and ligand be a complex.
  • Data: The project code contain two parts. The first one is ProbalilisticMetricSpaces, the second on in a notebook, by request.

  • Basic solution: The solution is a linear combination, it is described in this paper, and draft.
  • Method: We propose a novel approach to reconstruct distribution of bonding angles and solve the scoring problem as a problem of metric classification.

Current goals

  1. To run the basic code with slight model variations and repeat the computational experiment
  2. To combine the probability distributions with the basic code
  3. To develop the model and beat the tests
