摘要

Machine learning (ML) has the potential to advance materials science. However, ML algorithm selection is often ad hoc; limiting the performance and impact of ML, and guidance on choosing appropriate algorithms is scarce. We explore a subset of ML algorithms applied to diverse applications involving both experimental and computational data, and utilizing regression, interpolation, and optimization ML methods. We study three applications involving distinct data regimes and goals, allowing us to compare the performance of algorithms. We provide practical insights into algorithm selection, frameworks for studying algorithmic choice, and encourage further investigation into this critical but underexplored aspect of ML.
