default_dist_funs {RAFS}

Default feature dissimilarity functions

Description

As used in run_rafs.

Usage

default_dist_funs

Format

An object of class list of length 3.

Details

The default functions compute: Pearson's correlation (cor: cor_dist), Variation of Information (vi: vi_dist) and Symmetric Target Information Gain (stig: stig_dist).

These functions follow a similar protocol to default_fs_fun. They expect the same input except for the assumption that the data passed in is relevant. Each of them outputs a matrix of distances (dissimilarities) between features.
