R-Searcher: Calibrating Retrieval and Reasoning Boundaries for Agentic Search

Sheng Zhang, Junyi Li, Wenlin Zhang +6

Recent search agents for multi-hop reasoning often fail by either retrieving incomplete evidence or reasoning over irrelevant portions of the retrieved content, leading to a retrie…

Evoking User Memory: Personalizing LLM via Recollection-Familiarity Adaptive Retrieval

Yingyi Zhang, Junyi Li, Wenlin Zhang +8

Personalized large language models (LLMs) rely on memory retrieval to incorporate user-specific histories, preferences, and contexts. Existing approaches either overload the LLM by…
