Retrieving, Rethinking and Revising: The Chain-of-Verification Can Improve Retrieval Augmented Generation

no code implementations8 Oct 2024 Bolei He, Nuo Chen, Xinran He, Lingyong Yan, Zhenkai Wei, Jinchang Luo, Zhen-Hua Ling

To address these issues, we propose the chain-of-verification (CoV-RAG) to enhance the external retrieval correctness and internal generation consistency.

Which Side Are You On? A Multi-task Dataset for End-to-End Argument Summarisation and Evaluation

2 code implementations5 Jun 2024 Hao Li, Yuping Wu, Viktor Schlegel, Riza Batista-Navarro, Tharindu Madusanka, Iqra Zahid, Jiayan Zeng, Xiaochi Wang, Xinran He, Yizhi Li, Goran Nenadic

In our work, we introduce an argument mining dataset that captures the end-to-end process of preparing an argumentative essay for a debate, which covers the tasks of claim and evidence identification (Task 1 ED), evidence convincingness ranking (Task 2 ECR), argumentative essay summarisation and human preference ranking (Task 3 ASR) and metric learning for automated evaluation of resulting essays, based on human feedback along argument quality dimensions (Task 4 SQE).

Network Inference from a Mixture of Diffusion Models for Fake News Mitigation

no code implementations8 Aug 2020 Karishma Sharma, Xinran He, Sungyong Seo, Yan Liu

Users influential in the propagation of true and fake contents are identified using the inferred diffusion dynamics.

DynGEM: Deep Embedding Method for Dynamic Graphs

1 code implementation29 May 2018 Palash Goyal, Nitin Kamra, Xinran He, Yan Liu

The major advantages of DynGEM include: (1) the embedding is stable over time, (2) it can handle growing dynamic graphs, and (3) it has better running time than using static embedding methods on each snapshot of a dynamic graph.

mvn2vec: Preservation and Collaboration in Multi-View Network Embedding

3 code implementations19 Jan 2018 Yu Shi, Fangqiu Han, Xinwei He, Xinran He, Carl Yang, Jie Luo, Jiawei Han

With experiments on a series of synthetic datasets, a large-scale internal Snapchat dataset, and two public datasets, we confirm the validity and importance of preservation and collaboration as two objectives for multi-view network embedding.

Learning Influence Functions from Incomplete Observations

no code implementations NeurIPS 2016 Xinran He, Ke Xu, David Kempe, Yan Liu

We establish both proper and improper PAC learnability of influence functions under randomly missing observations.

Learning and Optimization with Submodular Functions

no code implementations7 May 2015 Bharath Sankaran, Marjan Ghazvininejad, Xinran He, David Kale, Liron Cohen

Set functions, and specifically submodular set functions, characterize a wide variety of naturally occurring optimization problems, and the property of submodularity of set functions has deep theoretical consequences with wide ranging applications.

GLAD: Group Anomaly Detection in Social Media Analysis- Extended Abstract

no code implementations7 Oct 2014 QI, Yu, Xinran He, Yan Liu

Existing group anomaly detection approaches rely on the assumption that the groups are known, which can hardly be true in real world social media applications.
