The constant regret bound significantly improves previous results which had O(log^(2/3) d · T^(1/3)) regret

"Our constant regret bound significantly improves previous results with $O(\log ^{2/3}d \cdot T^{1/3})$ regret [Cevher, Cutkosky, Kavis, Piliouras, Skoulakis, Viano, NeurIPS 2023, Hait, Li, Luo, Zhang, COLT 2025]."

An algorithm achieves O(log d) alternating regret for online linear optimization over the probability simplex, which remains constant for any time horizon T

"For OLO over the probability simplex $Δ_d$, we give an algorithm with $O(\log d)$ alternating regret that remains a constant for any time horizon $T$, and a matching lower bound."

The dual PCN approach results in more stable, continuous, online learning for time series anomaly detection
