Search-on-Graph-R1: Training Large Language Models to Search Knowledge Graphs with Reinforcement Learning

Jia Ao Sun, Hao Yu, Fengran Mo +4

Knowledge graph question answering (KGQA) requires navigating from topic entities to an answer several relations away. Recent methods prompt a frontier LLM to explore the graph thr…

Learning to Route Queries to Heads for Attention-based Re-ranking with Large Language Models

Yuxing Tian, Fengran Mo, Zhiqi Huang +2

Large Language Models (LLMs) have recently been explored as fine-grained zero-shot re-rankers by leveraging attention signals to estimate document relevance. However, existing meth…

Towards Dynamic Dense Retrieval with Routing Strategy

Zhan Su, Fengran Mo, Jinghan Zhang +4

The \textit{de facto} paradigm for applying dense retrieval (DR) to new tasks involves fine-tuning a pre-trained model for a specific task. However, this paradigm has two significa…

ReAttn: Improving Attention-based Re-ranking via Attention Re-weighting

Yuxing Tian, Fengran Mo, Weixu Zhang +2

The strong capabilities of recent Large Language Models (LLMs) have made them highly effective for zero-shot re-ranking task. Attention-based re-ranking methods, which derive relev…
