Abstract

Data-driven approaches now allow for systematic mapping of microstructure to properties. In particular, we now have d\ iverse approaches to "featurize" microstructures, creating a large pool of machine-readable descriptors for subsequent stru\ cture-property analysis. We explore three questions in this work: (a) Can a small subset of features be selected to train a\ good structure-property predictive model? (b) Is this subset agnostic to the choice of feature selection algorithm? And (c\ ) can the addition of expert-identified features improve model performance? Using a canonical dataset, we answer in the aff\ irmative for all three questions.
