Researchers have introduced Psi-Resilience, a novel model-free method for determining feature importance directly from data using 1D topological signals. This approach constructs a class-disagreement landscape and uses its topological features to generate a context-robust importance score. Evaluations on synthetic and real datasets show Psi-Resilience achieves high fidelity in recovering feature rankings, performing competitively with established methods like SHAP and mutual information.
