Researchers have identified a limitation in language agents where they do not effectively learn from past experiences to improve future decisions. Despite history generally aiding task completion, agents show little decline in success even when past actions are randomized, suggesting a failure to connect actions with their outcomes. To address this, a simple annotation of observations as outcomes of preceding actions improved success and reduced redundant actions. Further, a learned calibrator was developed to explicitly reassess past actions and selectively record experience, leading to enhanced task success. AI
IMPACT This research highlights a critical area for improvement in AI agents, suggesting that better mechanisms for learning from historical data are needed for more robust and efficient decision-making.
