Inverse design of bespoke interatomic potentials via active learning by information-matching
Researchers have developed a new active learning strategy called information-matching (IM) to create interatomic potentials (IPs) for materials science simulations. This method focuses on selecting training data that provides the most relevant information for predicting specific material properties, such as plastic strength in metals. By targeting inexpensive intermediate properties that correlate with strength, the IM approach allows for precise parameter constraints with minimal data, though model error remains a challenge that can be mitigated with post hoc uncertainty corrections.
