New method identifies causal vs. spurious features in AI models post-hoc

Researchers have introduced the Normalised Sensitivity Ratio (NSR), a novel post-hoc method for identifying causal features in trained AI models. Unlike previous techniques, NSR does not require access to the model's training procedure. It operates under a structured-shift regime where environments differ mainly in the mean of spurious features, while causal mechanisms remain stable. Experiments on synthetic data and real-world datasets like bike-sharing data have shown NSR's effectiveness in recovering causal features and its consistent performance across various model families.
