説明:

In this study, we demonstrate that the scaling law of simulation-to-real (Sim2Real) transfer learning holds for several machine learning tasks in materials science. Through three different prediction tasks for polymers and inorganic material systems, it was observed that the prediction error on real systems decreased monotonically with increasing the size of computational data according to a power law. Observing the scaling behavior offers various insights for advancing database development, such as determining the sample size necessary to achieve a desired predictive performance and a quantitative measure of the database’s potential value in real-world applications. Additionally, it aids in identifying equivalent sample sizes for physical and computational experiments and guiding the design of data production protocols principled the Sim2Realtransferability and scalability to downstream real-world tasks.
