Researchers have published new bounds for estimating discrete probability distributions using the $\ell_\infty$ norm. The work provides minimax bounds in expectation and high-probability tail bounds. This research resolves open questions from Kontorovich and Painsky (JMLR, 2025), including an empirical version of their tightest risk bound and the identification of the worst-case extremal distribution.
