On the Learnability of Offline Model-Based Optimization: A Ranking Perspective

Shen-Huan Lyu, Rong-Xi Tan, Ke Xue +4

Offline model-based optimization (MBO) seeks to discover high-performing designs using only a fixed dataset of past evaluations. Most existing methods rely on learning a surrogate…

Offline Model-Based Optimization by Learning to Rank

Rong-Xi Tan, Ke Xue, Shen-Huan Lyu +5

Offline model-based optimization (MBO) aims to identify a design that maximizes a black-box function using only a fixed, pre-collected dataset of designs and their corresponding sc…
