Finite Reliability Representations: Noise-Calibrated Belief-Space Covers for Reliable Decision-Making

arXiv:2607.04019v1 Announce Type: cross Abstract: Physical sensing and actuation noise floors should inform how much belief resolution a decision-making system can reliably use. We introduce Finite Reliability Representations (FRR), a framework for covering belief spaces by reliability cells: regions within which the optimal action-value function Q*(b,u) varies by at most a tolerance epsilon, uniformly over actions. The framework is formulated on beliefs rather than states and uses a cover rather than an equivalence quotient, because approximate decision-closeness is not transitive in general.

Why this matters
Why now

The increasing complexity and autonomy of AI systems necessitate more reliable decision-making under uncertainty, which this framework directly addresses.

Why it’s important

This research provides a foundational approach for building more robust and trustworthy autonomous systems by explicitly accounting for limits in sensing and actuation, crucial for widespread adoption.

What changes

The explicit incorporation of noise-calibrated reliability into AI decision-making shifts the paradigm from theoretical optimality to practical, robust performance in real-world messy environments.
