The Cost Geometry of Belief: finite-resource inference under noisy observation

arXiv:2606.21585v2 Announce Type: replace Abstract: A finite machine's digital twin of a system observes the territory through finite, noisy sensors; we model its coherent output as a belief, a probability density over states, the Bayes posterior, never a point. Certainty, the perfect twin, is denied twice, by observation and by physics, both read off the Fisher information. To make this finiteness geometric, we model what it costs to change a belief: a belief-cost geometry, optimal transport in Wasserstein space reweighted conformally by Fisher information. The framework rests on two posed co

Why this matters
Why now

This research emerges as the limitations of current AI systems in handling uncertainty and resource constraints become more apparent, necessitating foundational theoretical advancements.

Why it’s important

It introduces a geometric framework for understanding belief updates under finite resources and noisy observations, potentially leading to more robust and resource-efficient AI models.
