Learning Probabilistic Filters with Strictly Proper Scoring Rules

arXiv:2606.26497v1 Announce Type: new Abstract: Bayesian filtering of partially and noisily observed dynamical systems seeks to infer the evolving conditional distribution of the state of a dynamical system, given observations, in an online fashion. This Bayesian filtering distribution is the natural object for uncertainty quantification, but it is rarely available as a supervised learning target. However, one can often use the forecast model to generate synthetic system trajectories, along with synthetic observations. We introduce the proper scoring ensemble filter (PSEF), an ensemble data as

Why this matters
Why now

The continuous drive for more robust and reliable AI systems, especially in dynamic and uncertain environments, necessitates advancements in probabilistic modeling and uncertainty quantification.

Why it’s important

Improved probabilistic filtering techniques could lead to more robust and accurate AI systems capable of operating in real-world conditions where data is noisy and incomplete.
