BiGCN: Leveraging Cell and Gene Similarities for Single-cell Transcriptome Imputation with Bi-Graph Convolutional Networks

1 code implementation bioRxiv 2024 Yoshitaka Inoue, Ethan Kulman, Rui Kuang

In both the imputation and the cluster tasks, BiGCN consistently outperformed two variants of BiGCN that solely relied on either the gene co-expression graph or cell similarity graph.

Scalable Label Propagation for Multi-relational Learning on the Tensor Product of Graphs

1 code implementation20 Feb 2018 Zhuliu Li, Raphael Petegrosso, Shaden Smith, David Sterling, George Karypis, Rui Kuang

In this paper, we generalize a widely used label propagation model to the normalized tensor product graph, and propose an optimization formulation and a scalable Low-rank Tensor-based Label Propagation algorithm (LowrankTLP) to infer multi-relations for two learning tasks, hyperlink prediction and multiple graph alignment.

Low-rank Label Propagation for Semi-supervised Learning with 100 Millions Samples

no code implementations28 Feb 2017 Raphael Petegrosso, Wei zhang, Zhuliu Li, Yousef Saad, Rui Kuang

The success of semi-supervised learning crucially relies on the scalability to a huge amount of unlabelled data that are needed to capture the underlying manifold structure for better classification.

Network-based Isoform Quantification with RNA-Seq Data for Cancer Transcriptome Analysis

no code implementations20 Mar 2014 Wei Zhang, Jae-Woong Chang, Lilong Lin, Kay Minn, Baolin Wu, Jeremy Chien, Jeongsik Yong, Hui Zheng, Rui Kuang

Based on our observation that the abundances of the neighboring isoforms by domain-domain interactions in the network are positively correlated, Net-RSTQ models the expression of the neighboring transcripts as Dirichlet priors on the likelihood of the observed read alignments against the transcripts in one gene.
