A Closed-Form Upper Bound for Admissible Learning-Rate Steps in Belief-Space Dynamics: 1 upvotes on Hugging Face Daily Papers, #63 of 68 papers on 2026-05-12. Day-by-day upvote history.

Learning-rate steps are usually treated as hyperparameters. This paper isolates a local beliefspace calculation: when an update is modeled as a projected forward step on the probability simplex, admissibility means contractivity in the natural KL/Bregman geometry. Under this model, the upper bound of an admissible step is not a tuning slogan but a formula.
