## Abstract (arXiv)

We study the problem of full-information online learning in the "bounded recall" setting popular in the study of repeated games. An online learning algorithm A is M-textitbounded-recall if its output at time t can be written as a function of the M previous rewards (and not e.g. any other internal state of A). We first demonstrate that a natural approach to constructing bounded-recall algorithms from mean-based no-regret learning algorithms (e.g., running Hedge over the last M rounds) fails, and that any such algorithm incurs constant regret per round. We then construct a stationary bounded-recall algorithm that achieves a per-round regret of Theta(1/√M), which we complement with a tight lower bound. Finally, we show that unlike the perfect recall setting, any low regret bound bounded-recall algorithm must be aware of the ordering of the past M losses -- any bounded-recall algorithm which plays a symmetric function of the past M losses must incur constant regret per round.
