Researchers have introduced HERO, a novel framework for reinforcement learning agents designed to improve multi-turn decision-making. Unlike traditional methods that rely on terminal outcomes, HERO uses hindsight-enhanced self-distillation with next environment observations as localized feedback. This approach converts each observation into a compact turn-level diagnosis, providing actionable insights into the agent's actions. HERO has demonstrated improved task success and reduced unnecessary turns on benchmarks like TauBench and WebShop, particularly under limited training budgets where successful rollouts are infrequent.
