Feature selection methods such as Recursive Feature Elimination, or RFE, are a standard answer to the dimensionality problem.
D-FOCUS-X addresses this with what the authors call Feature-Interaction-Aware Recursive Feature Elimination.
The authors state that this mechanism has no direct equivalent in existing SHAP-based, RFE-based or filter-based feature selection methods applied to intrusion detection.
