Stochastic Data Acquisition for Answering Queries as Time Goes by
Summary: Sequential decision making: when to acquire data vs reuse stale results to answer time-evolving queries under costs. Proposes RL and tailored locality-sensitive hashing; experiments on two real datasets show effective cost–accuracy trade-offs. (summarized by gpt-5-nano on Feb 09 2026)
