Researchers have introduced Causal Integrated Gradients (CIG) and Causal Expected Gradients (CEG), new methods for feature attribution in machine learning that incorporate prior causal structure among input features. These methods extend existing techniques by routing the integration path along a causal graph, allowing for the decomposition of a feature's attribution into direct and mediated effects. Evaluations on synthetic data, simulated gene expression data, and real-world interferon stimulation data demonstrate that CIG can more accurately identify upstream drivers compared to traditional methods like DeepSHAP and integrated gradients, without sacrificing scalability.
