Weband Schapire [1], Hart and Mas Colell [17, 18]. For example, it is shown in [1] that Hannan consistency is achievable in this case as well. Sequential decision problems like the ones considered in this paper have been studied in different fields under various names such as repeated games, regret minimization, on-line learning, prediction WebOct 5, 2016 · Fictitious play is a simple and widely studied adaptive heuristic for playing repeated games. It is well known that fictitious play fails to be Hannan consistent. …

WebWe will also consider the case of Hannan consistency. Indeed, any policy achieves at most an expected regret of order n: because of the equality ∑K k=1Tk(n)=n and thanks to Equation (1), one can show that EθRn ≤ nmaxk ∆k. More intuitively, this comes from the fact that the average cost of pulling an arm k is a constant ∆k. As a ... WebHannan consistency is equivalent to requiring that for all a1 ∈ A1, there holds: liminf T→∞ ΠˆT(a 1) ≥ 0. We thus conclude: there exist Hannan consistent algorithms for player 1 if and only if the nonneg-ative orthant S = {u : u(a1) ≥ 0,a1 ∈ A1} is approachable for player 1 in the zero-sum game with vector-valued payoffsΠˆ.
WebJan 1, 2015 · The claim that there exists a consistent learner under this randomized setting follows from Theorem 2 below. Intuitively, now the learner sits in the middle (x = 1∕2) and leans toward the better constant predictor fast enough. The previous example shows that consistency may not always be achievable.
Webrequire that the algorithm is Hannan consistent, i.e., Rn/n ! 0 with probability one.
