Abstract

Autonomous experimentation achieves user objectives more efficiently than Edisonian studies by combining machine learning and laboratory automation to iteratively select and perform experiments. Integrating knowledge from theory, simulations, literature, and human intuition into the machine learning model can further increase this advantage. We present a set of methods for probabilistically integrating human input into an autonomous materials exploration campaign for composition-structure phase mapping. During the campaign, the user can provide input by indicating potential phase boundaries or phase regions with their uncertainty or indicating regions of interest. The input is then integrated through probabilistic priors, resulting in a probabilistic distribution over potential phase maps given the data, model, and human input. We demonstrate an improvement in phase-mapping performance given appropriate human input.
