Nearly Optimal Fixed-Confidence Best-Arm Identification with 1-Bit Feedback
We study fixed-confidence best-arm identification under strict 1-bit feedback constraints. At each round, the learner selects an arm and a query set, and receives only a single bit indicating whether the sampled reward belongs to that set. We consider a distribution-free finite-variance setting with arm-wise localizati...
