Knowledge-Enhanced Attentive Learning for Answer Selection in Community Question Answering Systems

no code implementations17 Dec 2019 Fengshi Jing, Qingpeng Zhang

We propose the Knowledge-enhanced Attentive Answer Selection (KAAS) model, which enhances the performance through (a) considering both the expertise and the authority of the answerer; (b) utilizing the human-labeled tags, the taxonomy of the tags, and the votes as the domain knowledge to infer the expertise of the answer; (c) using matrix decomposition of the social network (formed by following-relationship) to infer the authority of the answerer and incorporating such information in the process of evaluating the similarity between segments.

A hybrid machine learning framework for analyzing human decision making through learning preferences

no code implementations4 Jun 2019 Mengzhuo Guo, Qingpeng Zhang, Xiuwu Liao, Frank Youhua Chen, Daniel Dajun Zeng

To meet the decision maker's demand for more interpretable machine learning models, we propose a novel hybrid method, namely Neural Network-based Multiple Criteria Decision Aiding, which combines an additive value model and a fully-connected multilayer perceptron (MLP) to achieve good performance while capturing the explicit relationships between individual attributes and the prediction.

Evolution of the Chinese Guarantee Network under Financial Crisis and Stimulus Program

no code implementations2 Apr 2018 Yingli Wang, Qingpeng Zhang, Xiaoguang Yang

Our knowledge about the evolution of guarantee network in downturn period is limited due to the lack of comprehensive data of the whole credit system.

A Reference-Free Algorithm for Computational Normalization of Shotgun Sequencing Data

no code implementations21 Mar 2012 C. Titus Brown, Adina Howe, Qingpeng Zhang, Alexis B. Pyrkosz, Timothy H. Brom

We here describe digital normalization, a single-pass computational algorithm that systematizes coverage in shotgun sequencing data sets, thereby decreasing sampling variation, discarding redundant data, and removing the majority of errors.
