Sharp Characterization of Bias in Post-Bandit Inference

Bandit algorithms generate data for downstream inference, but adaptive sampling biases post-bandit sample means. We analyze this bias for stable index algorithms, including UCB1 and its generalizations, and derive sharp leading-order expressions for the sample-mean bias and expected $Z$-statistic, in bandit experiments...

Characterizing Bias in Post-Bandit Inference under Index Algorithms

Bandit algorithms generate data for downstream inference, but adaptive sampling biases post-bandit sample means. We analyze this bias for stable index algorithms, including UCB1 and its generalizations, and derive sharp leading-order expressions for the sample-mean bias and expected $Z$-statistic. Our characterization...

Polynomial-Time Algorithm for Optimal Stopping with Fixed Accuracy

This work develops a novel expansion representation for the OS value and proves that truncating this expansion yields a simulation-based algorithm that implements an optimal stopping policy with computational complexity scaling polynomially in the time horizon and the underlying dimension.
