Spatial Temporal Graph Convolution with Graph Structure Self-learning for Early MCI Detection

no code implementations11 Nov 2022 Yunpeng Zhao, Fugen Zhou, Bin Guo, Bo Liu

The proposed spatial temporal graph convolution block directly exploits BOLD time series as input features, which provides an interesting view for rsfMRI-based preclinical AD diagnosis.

Variational Estimators of the Degree-corrected Latent Block Model for Bipartite Networks

no code implementations16 Jun 2022 Yunpeng Zhao, Ning Hao, Ji Zhu

Biclustering on bipartite graphs is an unsupervised learning task that simultaneously clusters the two types of objects in the graph, for example, users and movies in a movie review dataset.

Deep Learning Models in Detection of Dietary Supplement Adverse Event Signals from Twitter

no code implementations21 Jun 2021 Yefeng Wang, Yunpeng Zhao, Jiang Bian, Rui Zhang

We chose the best performing models in each task to assemble an end-to-end deep learning pipeline to detect DS AE signals and compared the results to the known DS AEs from a DS knowledge base (i. e., iDISK).

Identifiability and consistency of network inference using the hub model and variants

no code implementations21 Apr 2020 Yunpeng Zhao, Peter Bickel, Charles Weko

Identifiability of parameters is a notoriously difficult problem for Bernoulli mixture models.

Integrating Crowdsourcing and Active Learning for Classification of Work-Life Events from Tweets

no code implementations26 Mar 2020 Yunpeng Zhao, Mattia Prosperi, Tianchen Lyu, Yi Guo, Jiang Bian

Results show that crowdsourcing is useful to create high-quality annotations and active learning helps in reducing the number of required tweets, although there was no substantial difference among the strategies tested.

Logistic Regression Augmented Community Detection for Network Data with Application in Identifying Autism-Related Gene Pathways

no code implementations7 Sep 2018 Yunpeng Zhao, Qing Pan, Chengan Du

When searching for gene pathways leading to specific disease outcomes, additional information on gene characteristics is often available that may facilitate to differentiate genes related to the disease from irrelevant background when connections involving both types of genes are observed and their relationships to the disease are unknown.

Network Inference from Temporal-Dependent Grouped Observations

no code implementations25 Aug 2018 Yunpeng Zhao

In this article, we generalize the idea of the hub model into the case of grouped observations with temporal dependence.

On Consistency of Graph-based Semi-supervised Learning

no code implementations17 Mar 2017 Chengan Du, Yunpeng Zhao, Feng Wang

We prove the consistency of graph-based learning in the case that the estimated scores are enforced to be equal to the observed responses for the labeled data.
