Structured Nonnegative Matrix Factorization for Traffic Flow Estimation of Large Cloud Networks
Syed Muhammad Atif, Nicolas Gillis, Sameer Qazi +1
Network traffic matrix estimation is an ill-posed linear inverse problem: it requires to estimate the unobservable origin destination traffic flows, X, given the observable link tr…
A Novel Compressed Sensing Technique for Traffic Matrix Estimation of Software Defined Cloud Networks
Sameer Qazi, Syed Muhammad Atif, Muhammad Bilal Kadri
Traffic Matrix estimation has always caught attention from researchers for better network management and future planning. With the advent of high traffic loads due to Cloud Computi…
Tri-Compress: A Cascaded Data Compression Framework for Smart Electricity Distribution Systems
Syed Muhammad Atif, Anees Ahmed, Sameer Qazi
Modern smart distribution system requires storage, transmission and processing of big data generated by sensors installed in electric meters. On one hand, this data is essentially…
Improved SVD-based Initialization for Nonnegative Matrix Factorization using Low-Rank Correction
Atif Muhammad Syed, Sameer Qazi, Nicolas Gillis
Due to the iterative nature of most nonnegative matrix factorization (\textsc{NMF}) algorithms, initialization is a key aspect as it significantly influences both the convergence a…
Disjoint-Path Selection in Internet: What traceroutes tell us?
Sameer Qazi, Tim Moors
Routing policies used in the Internet can be restrictive, limiting communication between source-destination pairs to one path, when often better alternatives exist. To avoid route…
Finding Alternate Paths in the Internet:A Survey of Techniques for End-to-End Path Discovery
Sameer Qazi, Tim Moors
The Internet provides physical path diversity between a large number of hosts, making it possible for networks to use alternative paths when one path fails to deliver the required…
