Multiview Graph Learning with Consensus Graph

no code implementations24 Jan 2024 Abdullah Karaaslanli, Selin Aviyente

In particular, we propose an optimization problem, where graph data is assumed to be smooth over the multiview graph and the topology of the individual views and that of the consensus graph are learned, simultaneously.

Community detection in multiplex networks based on orthogonal nonnegative matrix tri-factorization

no code implementations2 May 2022 Meiby Ortiz-Bouza, Selin Aviyente

In this paper, we introduce a new multiplex community detection method that identifies communities that are common across layers as well as those that are unique to each layer.

Low-rank on Graphs plus Temporally Smooth Sparse Decomposition for Anomaly Detection in Spatiotemporal Data

no code implementations23 Oct 2020 Seyyid Emre Sofuoglu, Selin Aviyente

In particular, the anomaly detection problem is formulated as a robust lowrank + sparse tensor decomposition with a regularization term that minimizes the temporal variation of the sparse part, so that the extracted anomalies are temporally persistent.
