Simulation-to-Real (Sim2Real) transfer learning is gaining attention in materials science as a solution to the scarcity of experimental data.
A transfer learning scheme from first-principles calculations to experiments based on chemistry-informed domain transformation is proposed.
The proposed method efficiently bridges the simulation space (source domain) and the experimental data space (target domain) using prior knowledge of chemistry and the relationship between source and target quantities.
The transfer learning model exhibits high accuracy and data efficiency, even with a small number of target data, helping to save the number of trials in real laboratories.
