Light Gradient Boosting Machine as a Regression Method for Quantitative Structure-Activity Relationships

no code implementations28 Apr 2021 Robert P. Sheridan, Andy Liaw, Matthew Tudor

In the pharmaceutical industry, where it is common to generate many QSAR models with large numbers of molecules and descriptors, the best QSAR methods are those that can generate the most accurate predictions but that are also insensitive to hyperparameters and are computationally efficient.
