Beyond Isolated Behaviors: Hierarchical User Modeling for LLM Personalization 事件

Beyond Isolated Behaviors: Hierarchical User Modeling for LLM Personalization arXiv:2606.02300v1 Announce Type: new Abstract: Large Language Models (LLMs) have demonstrated remarkable capabilities across diverse domains, yet personalizing their outputs to individual users remains an open challenge. Existing approaches predominantly adopt a flat behavioral paradigm, aggregating user behaviors without an explicit account of how they are organized into deeper behavioral structures. In this work, w
