Transformer model TAMO performs multi-objective optimization in-context

Researchers have developed TAMO, a novel transformer-based policy for multi-objective Bayesian optimization that operates entirely in-context. This approach eliminates the need for per-task surrogate fitting and acquisition engineering, significantly reducing proposal time by up to 1000x. TAMO is pretrained using reinforcement learning to maximize cumulative hypervolume improvement, allowing it to approximate Pareto frontiers and improve solution quality under tight evaluation budgets. The development opens a path towards plug-and-play optimizers for scientific discovery. AI

IMPACT Enables faster, more adaptable optimization for scientific discovery workflows by eliminating per-task model fitting.
