arXiv:2606.09664v1 Announce Type: new Abstract: Bayesian optimization (BO) is a central tool for sample-efficient design, and latent-space Bayesian optimization (LSBO) extends it to structured objects such as molecules and proteins. In parallel, tabular foundation models such as TabPFN and TabICL now achieve state-of-the-art regression performance and are increasingly used as BO surrogates. Because their Bayesian behavior is induced by large synthetic pretraining collections, the composition of this pretraining distribution is crucial. LSBO creates a distinctive mismatch: the induced map from
This publication highlights continued advancements in AI optimization techniques, specifically addressing challenges in applying advanced foundation models to complex scientific design problems like molecular and protein engineering.
Improving the efficiency of optimizing structured objects accelerates discovery in critical fields like biotechnology and materials science, impacting industries from pharmaceuticals to advanced manufacturing.
The ability to more effectively use large tabular foundation models as Bayesian Optimization surrogates for latent space problems could significantly de-risk and speed up R&D cycles in areas previously limited by sample efficiency.
