ClueAnchor: Clue-Anchored Knowledge Reasoning Exploration and Optimization for Retrieval-Augmented Generation

EMNLP 2025

Retrieval-Augmented Generation (RAG) augments Large Language Models (LLMs) with external knowledge to improve factuality. However, existing RAG systems frequently underutilize the retrieved documents, failing to extract and integrate the key clues needed to support faithful and interpretable reasoni

GeoSafe: A Unified Unconstrained Multi-DOF Optimization Framework for Multi-UAV Cooperative Hoisting and Obstacle Avoidance

IROS 2025

In warehouse logistics and post-disaster rescue, multi-UAV payload transport must navigate tight spaces, such as 1.2m × 0.8m aisles and collapsed pipelines as narrow as 0.6m. Traditional four-DOF (translation and scaling) trajectory planning struggles under such constraints. To overcome this, we pro

RAG-DDR: Optimizing Retrieval-Augmented Generation Using Differentiable Data Rewards

ICLR 2025poster

Retrieval-Augmented Generation (RAG) has proven its effectiveness in mitigating hallucinations in Large Language Models (LLMs) by retrieving knowledge from external resources. To adapt LLMs for the RAG systems, current approaches use instruction tuning to optimize LLMs, improving their ability to ut…

MARVEL: Unlocking the Multi-Modal Capability of Dense Retrieval via Visual Module Plugin

ACL 2024long

This paper proposes Multi-modAl Retrieval model via Visual modulE pLugin (MARVEL), which learns an embedding space for queries and multi-modal documents to conduct retrieval. MARVEL encodes queries and multi-modal documents with a unified encoder model, which helps to alleviate the modality gap betw…
