Synergistic Weak-Strong Collaboration by Aligning Preferences

no code implementations21 Apr 2025 Yizhu Jiao, Xuchao Zhang, Zhaoyang Wang, Yubo Ma, Zhun Deng, Rujia Wang, Chetan Bansal, Saravan Rajmohan, Jiawei Han, Huaxiu Yao

To optimize this collaboration, we introduce a collaborative feedback to fine-tunes the weak model, which quantifies the influence of the weak model's contributions in the collaboration procedure and establishes preference pairs to guide preference tuning of the weak model.

Long Context vs. RAG for LLMs: An Evaluation and Revisits

1 code implementation27 Dec 2024 Xinze Li, Yixin Cao, Yubo Ma, Aixin Sun

Extending context windows (i. e., Long Context, LC) and using retrievers to selectively access relevant information (i. e., Retrieval-Augmented Generation, RAG) are the two main strategies to enable LLMs to incorporate extremely long external contexts.

TART: An Open-Source Tool-Augmented Framework for Explainable Table-based Reasoning

1 code implementation18 Sep 2024 Xinyuan Lu, Liangming Pan, Yubo Ma, Preslav Nakov, Min-Yen Kan

Current Large Language Models (LLMs) exhibit limited ability to understand table structures and to apply precise numerical reasoning, which is crucial for tasks such as table question answering (TQA) and table-based fact verification (TFV).

VLMEvalKit: An Open-Source Toolkit for Evaluating Large Multi-Modality Models

2 code implementations16 Jul 2024 Haodong Duan, Junming Yang, Yuxuan Qiao, Xinyu Fang, Lin Chen, YuAn Liu, Amit Agarwal, Zhe Chen, Mo Li, Yubo Ma, Hailong Sun, Xiangyu Zhao, Junbo Cui, Xiaoyi Dong, Yuhang Zang, Pan Zhang, Jiaqi Wang, Dahua Lin, Kai Chen

Based on the evaluation results obtained with the toolkit, we host OpenVLM Leaderboard, a comprehensive leaderboard to track the progress of multi-modality learning research.

SciAgent: Tool-augmented Language Models for Scientific Reasoning

no code implementations18 Feb 2024 Yubo Ma, Zhibin Gou, Junheng Hao, Ruochen Xu, Shuohang Wang, Liangming Pan, Yujiu Yang, Yixin Cao, Aixin Sun, Hany Awadalla, Weizhu Chen

To make this task more practical and solvable for LLMs, we introduce a new task setting named tool-augmented scientific reasoning.

Towards Verifiable Generation: A Benchmark for Knowledge-aware Language Model Attribution

1 code implementation9 Oct 2023 Xinze Li, Yixin Cao, Liangming Pan, Yubo Ma, Aixin Sun

Although achieving great success, Large Language Models (LLMs) usually suffer from unreliable hallucinations.

Few-shot Event Detection: An Empirical Study and a Unified View

1 code implementation3 May 2023 Yubo Ma, Zehao Wang, Yixin Cao, Aixin Sun

Few-shot event detection (ED) has been widely studied, while this brings noticeable discrepancies, e. g., various motivations, tasks, and experimental settings, that hinder the understanding of models for future progress. This paper presents a thorough empirical study, a unified view of ED models, and a better unified baseline.

Information Extraction in Low-Resource Scenarios: Survey and Perspective

3 code implementations16 Feb 2022 Shumin Deng, Yubo Ma, Ningyu Zhang, Yixin Cao, Bryan Hooi

Information Extraction (IE) seeks to derive structured information from unstructured texts, often facing challenges in low-resource scenarios due to data scarcity and unseen classes.
