This chapter reviews techniques for learning causal relationships from data, in application to the problem of feature selection, and highlights the benefits that causal discovery may draw from recent developments in feature selection theory and algorithms.
Abstract
The present chapter makes an argument in favor of understanding and utilizing the notion of causality for feature selection: from an algorithm design perspective, to enhance interpretation, build robustness against violations of the i.i.d. assumption, and increase parsimony of selected feature sets; from the perspective of method characterization, to help uncover superfluous or artifactual selected features, missed features, and features not only predictive but also causally informative.
