arXiv:2512.24152v2 Announce Type: replace-cross Abstract: Sampling based on score diffusions has led to striking empirical results, and has attracted considerable attention from various research communities. It depends on availability of (approximate) Stein score functions for various levels of additive noise. We show how in some generality, the availability of scores allows the general problem to be ``reduced'' to sampling from an adaptively constructed sequence of $K$ strongly log-concave (SLC) sub-problems. The reduction is simple, constructive and algorithm-independent, so that any SLC sam
This paper represents continued academic progress in the mathematical and algorithmic foundations of sampling, a core component of modern AI systems.
Improved sampling methods can lead to more efficient and reliable AI model training and inference, impacting various AI applications.
The proposed 'reduction' method offers a more structured and potentially robust approach to score-based sampling by breaking down complex problems into a series of strongly log-concave sub-problems.
