LMEB: Long-horizon Memory Embedding Benchmark

Xinping Zhao, Xinshuo Hu, Jiaxin Xu +9

The paper presents LMEB, a benchmark suite of 22 datasets and 193 zero-shot retrieval tasks designed to evaluate how well text embedding models handle long-horizon, context‑depende…

KaLM-Reranker-V1: Fast but Not Late Interaction for Compressed Document Reranking

Xinping Zhao, Jiaxin Xu, Ziqi Dai +7

As retrieval systems scale, high-quality reranking becomes increasingly important. However, most existing rerankers, whether encoder-based or decoder-based, jointly encode the quer…

Learning to Extract Rational Evidence via Reinforcement Learning for Retrieval-Augmented Generation

Xinping Zhao, Shouzheng Huang, Yan Zhong +4

Retrieval-Augmented Generation (RAG) effectively improves the accuracy of Large Language Models (LLMs). However, retrieval noises significantly undermine the quality of LLMs' gener…

FunnelRAG: A Coarse-to-Fine Progressive Retrieval Paradigm for RAG

Xinping Zhao, Yan Zhong, Zetian Sun +5

Retrieval-Augmented Generation (RAG) prevails in Large Language Models. It mainly consists of retrieval and generation. The retrieval modules (a.k.a. retrievers) aim to find useful…
