Research Type Theoretical In this paper, we employ continuous-time stochastic calculus in order to study the discrete-time experts problem. We use these tools to design a continuous-time, parameter-free algorithm with improved guarantees on the quantile regret. We then develop an analogous discrete-time algorithm with a very similar analysis and identical quantile regret bounds. Finally, we design an anytime continuous-time algorithm with regret matching the optimal fixed-time rate when the gains are independent Brownian motions; in many settings, this is the most difficult case. This gives some evidence that, even with adversarial gains, the optimal anytime and fixed-time regrets may coincide.
