Minimax-Optimal Small-Loss Bounds for Online Linear Optimisation on Balls
Jack J. Mayo
We study full-information online linear optimisation on the unit ball in , for fixed and losses of dual norm at most one. Let denote th…
First- and Second-Order Bounds for Adversarial Linear Contextual Bandits
Julia Olkhovskaya, Jack Mayo, Tim van Erven +2
We consider the adversarial linear contextual bandit setting, which allows for the loss functions associated with each of arms to change over time without restriction. Assuming…
Scale-free Unconstrained Online Learning for Curved Losses
Jack J. Mayo, Hédi Hadiji, Tim van Erven
A sequence of works in unconstrained online convex optimisation have investigated the possibility of adapting simultaneously to the norm of the comparator and the maximum norm…
Distribution of Kinks in an Ising Ferromagnet After Annealing and the Generalized Kibble-Zurek Mechanism
Jack J. Mayo, Zhijie Fan, Gia-Wei Chern +1
We consider the annealing dynamics of a one-dimensional Ising ferromagnet induced by a temperature quench in finite time. In the limit of slow cooling, the asymptotic two-point cor…
Full Counting Statistics of Topological Defects After Crossing a Phase Transition
Fernando J. Gómez-Ruiz, Jack J. Mayo, Adolfo del Campo
We consider the number distribution of topological defects resulting from the finite-time crossing of a continuous phase transition and identify signatures of universality beyond t…
