Researchers have demonstrated a method to aggregate asymptotically optimal sequential tests into log-optimal e-processes. This work proves the converse of a previous finding, establishing that optimal sequential tests can indeed be constructed from these e-processes. The new approach utilizes a novel class of WAIT e-processes, which are weighted aggregates of indicators of stopping times. AI
IMPACT This research advances theoretical understanding in sequential testing, which could have downstream implications for AI systems that require efficient decision-making under uncertainty.
