arXiv:2606.27090v1 Announce Type: cross Abstract: Global objectives, such as KL divergence and ELBO, are widely used in Bayesian inference for measuring distributional discrepancy. This paper studies their local-mass behaviour that is not directly captured by such objectives. We introduce and use two mathematical tools: (1) Mass Index for recording the polynomial and logarithmic decay scales of local mass, and (2) regularised extended KL (RE-KL), a set-localised divergence that can be formulated in the presence of singular components. Mass Indices help characterise how Bayesian updating change
This research is being published as AI models become increasingly complex, necessitating more robust and nuanced methods for Bayesian inference to ensure their reliability and interpretability.
Improved Bayesian inference techniques, especially those addressing local-mass behavior, could lead to more accurate, efficient, and trustworthy AI systems, which is critical for their adoption in sensitive applications.
This research introduces new mathematical tools for understanding and measuring distributional discrepancies in Bayesian inference beyond global objectives, potentially refining how AI models are trained and evaluated.
