High Performance Learning with the Unite and Conquer Approach

Event Details

 Abstract: The ever-increasing production of data requires new methodological and technological approaches to meet the challenge of their effective analyses. We highlight the omnipresence of certain linear algebra methods such as the eigenvalue problem or more generally the singular value decomposition in machine learning techniques. A new machine learning approach based on Unite and Conquer methods, used in linear algebra, will be presented. The important characteristics of this intrinsically parallel and scalable technique make it very well suited to multi-level and heterogeneous parallel and/or distributed architectures. We also underline the important role that platforms like YML and Pegasus can play to facilitate the implementation of these methods on these architectures. Experimental results, demonstrating the interest of the approach for efficient data analysis in the case of clustering, cybersecurity and road traffic simulation will be presented.
