Large-scale subspace clustering using sketching and validation
Panagiotis A. Traganitis, Konstantinos Slavakis, Georgios B. Giannakis
The nowadays massive amounts of generated and communicated data present major challenges in their processing. While capable of successfully classifying nonlinearly separable object…
Sketch and Validate for Big Data Clustering
Panagiotis A. Traganitis, Konstantinos Slavakis, Georgios B. Giannakis
In response to the need for learning tools tuned to big data analytics, the present paper introduces a framework for efficient clustering of huge sets of (possibly high-dimensional…
Per-Block-Convex Data Modeling by Accelerated Stochastic Approximation
Konstantinos Slavakis, Georgios B. Giannakis
Applications involving dictionary learning, non-negative matrix factorization, subspace clustering, and parallel factor tensor decomposition tasks motivate well algorithms for per-…
