Fractal structures in Adversarial Prediction

no code implementations29 Apr 2013 Rina Panigrahy, Preyas Popat

In this work we study how "fractal-like" processes arise in a prediction game where an adversary is generating a sequence of bits and an algorithm is trying to predict them.

Optimal amortized regret in every interval

no code implementations29 Apr 2013 Rina Panigrahy, Preyas Popat

In this paper we show a randomized algorithm that in an amortized sense gets a regret of $O(\sqrt x)$ for any interval when the sequence is partitioned into intervals arbitrarily.
