Abstract For many machine learning applications in science, data acquisition, not training, is the bottleneck even when avoiding experiments and relying on computation simulation. Correspondingly, order to reduce cost carbon footprint, training efficiency key.

Abstract Scientific machine learning (ML) aims to develop generalizable models, yet assessments of generalizability often rely on heuristics. Here, we demonstrate in the materials science setting that heuristic evaluations lead biased conclusions ML and benefits neural scaling, through out-of-distribution (OOD) tasks involving unseen chemistry or structural symmetries. Surprisingly, many good performance across including boosted trees. However, analysis representation space shows most test data reside within regions well-covered by training data, while poorly-performing involve outside domain. For these challenging tasks, increasing size time yields limited adverse effects, contrary traditional scaling trends. Our findings highlight OOD tests reflect interpolation, not true extrapolation, leading overestimations benefits. This emphasizes need for rigorously benchmarks.
