Stability Measures for Feature Selection

An implementation of many measures for the assessment of the stability of feature selection. Both simple measures and measures which take into account the similarities between features are available, see Bommert (2020) .

stabm

stabm provides an implementation of many measures which assess the stability of feature selection. The following stability measures are currently included:
