ReliefF feature selection algorithms

Project description

This package contains implementations of the ReliefF family of feature selection algorithms: https://en.wikipedia.org/wiki/Relief_(feature_selection)

These algorithms excel at identifying features that are predictive of the outcome in supervised learning problems, and are especially good at identifying feature interactions that are normally overlooked by standard feature selection algorithms.

The main benefit of ReliefF algorithms is that they identify feature interactions without having to exhaustively check every pairwise interaction, thus taking significantly less time than exhaustive pairwise search.

ReliefF algorithms are commonly applied to genetic analyses, where epistasis (i.e., feature interactions) is common. However, the algorithms implemented in this package can be applied to any supervised classification data set.
