Unsupervised Feature Selection using the Heterogeneous Correlation Matrix

v1.0.1 · Nov 24, 2025 · GPL-2

Description

Unsupervised multivariate filter feature selection using the UFS-rHCM or UFS-cHCM algorithms based on the heterogeneous correlation matrix (HCM). The HCM consists of Pearson's correlations between numerical features, polyserial correlations between numerical and ordinal features, and polychoric correlations between ordinal features.
