Hit Expansion from Screening Data Based upon Conditional Probabilities of Activity Derived from SAR Matrices
Disha Gupta‐Ostermann, Jenny Balfer, Jürgen Bajorath · Molecular Informatics · 2015
A new methodology for activity prediction of compounds from SAR matrices is introduced that is based upon conditional probabilities of activity. The approach has low computational complexity, is primarily designed for hit expansion from biological screening data, and accurately predicts both active and inactive compounds. Its performance is comparable to state-of-the-art machine learning methods such as support vector machines or Bayesian classification. Matrix-based activity prediction of virtual compounds further extends the spectrum of computational methods for compound design.
