New algorithms offer improved regret bounds for online learning

A new research paper introduces algorithms for unconstrained online learning that offer improved regret bounds. These algorithms are parameter-free and achieve guarantees based on gradient variation, without needing prior knowledge of parameters like the comparator norm or Lipschitz constant. The findings extend to dynamic regret and offer significant improvements over previous results, particularly for the stochastically-extended adversarial model. AI

    Gradient-Variation Regret Bounds for Unconstrained Online Learning

    arXiv:2604.11151v2 Announce Type: replace-cross Abstract: We develop parameter-free algorithms for unconstrained online learning with regret guarantees that scale with the gradient variation $V_T(u) = \sum_{t=2}^T \|\nabla f_t(u)-\nabla f_{t-1}(u)\|^2$. For $L$-smooth convex loss…
