IntPro: A Proxy Agent for Context-Aware Intent Understanding via Retrieval-conditioned Inference

arXiv:2603.03325v1 Announce Type: cross Abstract: Large language models (LLMs) have become integral to modern Human-AI collaboration workflows, where accurately understanding user intent serves as a crucial step for generating satisfactory responses. Context-aware intent understanding, which involves inferring user intentions from situational environments, is inherently challenging because it requires reasoning over both the immediate context and the user's underlying motivations that drive their behavior. Moreover, existing approaches often treat intent understanding as a static recognition task, overlooking users' accumulated intent patterns that could provide valuable references for more accurate and generalizable understanding. To address this gap, we propose IntPro, a proxy agent that learns to adapt to individual users via retrieval-conditioned intent inference.

arXiv:2603.03325v1 Announce Type: cross Abstract: Large language models (LLMs) have become integral to modern Human-AI collaboration workflows, where accurately understanding user intent serves as a crucial step for generating satisfactory responses. Context-aware intent understanding, which involves inferring user intentions from situational environments, is inherently challenging because it requires reasoning over both the immediate context and the user's underlying motivations that drive their behavior. Moreover, existing approaches often treat intent understanding as a static recognition task, overlooking users' accumulated intent patterns that could provide valuable references for more accurate and generalizable understanding. To address this gap, we propose IntPro, a proxy agent that learns to adapt to individual users via retrieval-conditioned intent inference. We design intent explanations that abstract how contextual signals connect to expressed intents, and store them in an individual intent history library for retrieval. We train IntPro through supervised fine-tuning on retrieval-conditioned trajectories and multi-turn Group Relative Policy Optimization (GRPO) with tool-aware reward functions, enabling the agent to learn when to leverage historical intent patterns and when to infer directly. Experiments across three diverse scenarios (Highlight-Intent, MIntRec2.0, and Weibo Post-Sync) demonstrate that IntPro achieves strong intent understanding performance with effective context-aware reasoning capabilities across different scenarios and model types.

Executive Summary

This article introduces IntPro, a proxy agent that utilizes retrieval-conditioned inference to improve context-aware intent understanding in human-AI collaboration workflows. IntPro learns to adapt to individual users by storing their intent patterns in an individual intent history library for retrieval. The agent is trained through supervised fine-tuning and multi-turn Group Relative Policy Optimization (GRPO) with tool-aware reward functions. Experiments across three diverse scenarios demonstrate IntPro's strong intent understanding performance and effective context-aware reasoning capabilities. The proposed approach addresses the limitations of existing approaches by leveraging users' accumulated intent patterns and adapting to individual users. The results have significant implications for improving human-AI collaboration and enhancing the accuracy of intent understanding in various applications.
