Iterative subtraction method for Feature Ranking

no code implementations • 13 Jun 2019 • Paul Glaysher, Judith M. Katzy, Sitong An

Ranking methods, such as the BDT Selection Frequency commonly used in High Energy Physics and the Permutational Performance, are compared with the computationally expense Iterative Addition and Iterative Removal procedures, while the latter was found to be the most performant.
