Partitioning techniques classify large compound sets using dimension reduction for efficient molecular classification. This method differs from clustering, offering a novel approach for chemoinformatics databases.

Area of Science:

  • Chemoinformatics
  • Computational Chemistry
  • Data Science

Background:

  • Partitioning techniques are essential for classifying large compound sets based on chemical or biological criteria.
  • These methods are algorithmically distinct from clustering but serve similar purposes, especially for large datasets.
  • Current popular approaches involve reducing the dimensionality of chemical spaces.

Purpose of the Study:

  • To describe the principles and methodological aspects of dimension reduction in chemical spaces.
  • To explain the process of partitioning compounds within these reduced, low-dimensional spaces.
  • To highlight the utility of partitioning for molecular classification in chemoinformatics.

Main Methods:

  • Generation of original chemical reference spaces using molecular descriptors and properties.
