Random Feature-based Online Multi-kernel Learning in Environments with Unknown Dynamics
Yanning Shen, Tianyi Chen, Georgios B. Giannakis
Kernel-based methods exhibit well-documented performance in various nonlinear learning tasks. Most of them rely on a preselected kernel, whose prudent choice presumes task-specific…
Blind Multiclass Ensemble Classification
Panagiotis A. Traganitis, Alba Pagès-Zamora, Georgios B. Giannakis
The rising interest in pattern recognition and data analytics has spurred the development of innovative machine learning algorithms and tools. However, as each algorithm has its st…
Kernel-based Inference of Functions over Graphs
Vassilis N. Ioannidis, Meng Ma, Athanasios N. Nikolakopoulos +2
The study of networks has witnessed an explosive growth over the past decades with several ground-breaking methods introduced. A particularly interesting -- and prevalent in severa…
Sketched Subspace Clustering
Panagiotis A. Traganitis, Georgios B. Giannakis
The immense amount of daily generated and communicated data presents unique challenges in their processing. Clustering, the grouping of data without the presence of ground-truth la…
Data-adaptive Active Sampling for Efficient Graph-Cognizant Classification
Dimitris Berberidis, Georgios B. Giannakis
The present work deals with active sampling of graph nodes representing training data for binary classification. The graph may be given or constructed using similarity measures amo…
