Bridging data-driven priors via the score function for posterior sampling -- Comparative review and experimental study
arXiv:2606.14800v1 Announce Type: cross Abstract: This paper reviews how a diverse set of popular data-driven priors commonly used in Bayesian inverse problems can be unified through their respective score functions. By framing these priors under this common perspective, we show that they can benefit from their straightfoward and effective integration into a recently proposed sampling algorithm. The applicability of this common framework is illustrated by considering several data-driven priors, namely regularization-by-denoising, normalizing flow-based priors, score-based generative models, an
The paper is published as research in AI and Bayesian methods continues to accelerate, driven by the demand for more robust and efficient models capable of handling complex, real-world data challenges.
This work is important for strategic readers as it consolidates diverse data-driven priors under a unified framework, likely enhancing the efficiency and applicability of advanced AI sampling algorithms in various domains.
The proposed unified framework simplifies the integration of powerful data-driven priors, potentially leading to more effective and standardized approaches in Bayesian inverse problems and generative modeling.
