Beyond Token-level Supervision: Unlocking the Potential of Decoding-based Regression via Reinforcement Learning

ICML 2026poster

Decoding-based regression, which reformulates regression as a sequence generation task, has emerged as a promising paradigm of applying large language models for numerical prediction. However, its progress is hindered by the misalignment between discrete token-level objectives (e.g., cross-entropy) …

Offline Model-Based Optimization by Learning to Rank

ICLR 2025poster

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 scores. This problem has garnered significant attention from both scientific and industrial domains. A common approach in…

Towards Universal Offline Black-Box Optimization via Learning Language Model Embeddings

ICML 2025poster

The pursuit of universal black-box optimization (BBO) algorithms is a longstanding goal. However, unlike domains such as language or vision, where scaling structured data has driven generalization, progress in offline BBO remains hindered by the lack of unified representations for heterogeneous nume…
