Researchers have introduced a novel method for calculating feature importance in machine learning models, aiming to improve transparency and fairness. This new approach replaces traditional Monte Carlo shuffling with a single, deterministic permutation, significantly reducing computational cost and eliminating estimation variance. The method, termed Systemic Feature Importance (SFI), also incorporates empirical feature correlations to assess indirect reliance and extends scalar importance to a signed, directional representation. Empirical tests across numerous simulations and two real-world credit risk case studies demonstrate the framework's effectiveness in providing a principled and scalable approach to model governance.
