A Closer Look at Adaptive Regret
[chapter]
2012
Lecture Notes in Computer Science

We also prove that Fixed Share is optimal, in the sense that no algorithm can have a better adaptive regret bound. ...
Our main result is a thorough analysis of the adaptive regret of Fixed Share. We obtain the exact worst-case adaptive regret for Fixed Share, from which the classical tracking bounds can be derived. ...
Their adaptive regret bounds sport a term which exceeds 2 ln t 2 whereas our bounds (1) have at most a single ln t 2 . ...

We propose that e¤ort and regret are emotions produced by previous decisions to either resist or yield to temptation, respectively. ...
For instance, recall of regret experienced as a consequence of deciding to eat cake at lunch yesterday makes eating cake at lunch today less desirable. ...

Through these results we provide insight into the challenges and opportunities in using dueling bandit algorithms to run adaptive experiments. ...
Through this paper, we take a closer look at leveraging these dueling bandit algorithms for adaptive experimentation by empirically investigating the statistical properties of the DTS algorithm against ...

In this paper, we propose TSEB, a Thompson Sampling based algorithm with adaptive exploration bonus that aims to solve the problem with tighter PAC guarantees, while being cautious on the regret as well ...
At any given time, the agent solves a model sampled from this distribution, and the sampled reward distribution is skewed by an exploration bonus in order to generate more informative exploration. ...
From the literature, it is evident that quite a few approaches were looked at in solving for an optimal policy. ...

Focusing on the online bandit setting, we show that no bandit algorithm can guarantee a sublinear policy regret against an adaptive adversary with unbounded memory. ...
We define the alternative notion of policy regret, which attempts to provide a more meaningful way to measure an online algorithm's performance against adaptive adversaries. ...
A closer look at the proof of Thm. 2 reveals that it suffices to assume that A's regret bound holds against any loss sequence generated by a 1-memory-bounded adaptive adversary. ...

We further introduce a notion of regret for AIS and show that Daisee has O(√(T)( T)^3/4) cumulative pseudo-regret, where T is the number of iterations. ...
We then extend Daisee to adaptively learn a hierarchical partitioning of the sample space for more efficient sampling and confirm the performance of both algorithms empirically. ...
