From Static Context to Calibrated Interactive RL: Mitigating Distribution Shift in Multi-turn Dialogue with Aligned Simulator
arXiv:2605.26403v1 Announce Type: new Abstract: A long-standing goal of the research community is to develop highly interactive LLM-based dialogue agents. Recent research focuses on optimizing policies based on fixed offline logs (Static Context RL) or using a prompt-based simulator (Interactive RL). In this work, we theoretically show that both paradigms are fundamentally limited by context distribution shift--a mismatch between dialogue histories observed during training and those encountered in real conversations. This shift compounds quadratically over turns and severely degrades dialogue
This paper addresses a fundamental limitation in current AI training paradigms, highlighting a critical challenge that scales with the complexity of interactive AI systems.
It reveals a core algorithmic hurdle in developing truly robust and interactive LLM-based dialogue agents, impacting their reliability and real-world applicability.
The focus shifts towards mitigating context distribution shift as a primary goal in AI agent development, moving beyond static data optimization.
