PDF WebTo the best of our knowledge, this is the first result showing that the original Thompson Sampling is optimal for graphical bandits in the undirected setting. A slightly weaker regret bound of Thompson Sampling in the directed setting is also presented.

Stochastic Graphical Bandits with Adversarial Corruptions

Webbandits on graphs is similar to labeled graphs with bitonic paths in the graph theory literature (cf. (M¨uller-Hannemann & Weihe , 2001; Spinrad, 2003)). However, our … Webbandit literature. In this paper, we fill this gap and present the first regret-based algorithm for graphical bilinear bandits using the principle of optimism in the face of uncertainty. Theoretical analysis of this new method yields an upper bound of O˜(p T) on the ↵-regret and evidences the impact of the graph structure on the rate of ...
