A Scalable and Exact Relaxation for Densest -Subgraph via Error Bounds
Ya Liu, Junbin Liu, Wing-Kin Ma +1
Given an undirected graph and a size parameter , the Densest -Subgraph (DS) problem extracts the subgraph on vertices with the largest number of induced edges. While D…
Minimizing low-rank models of high-order tensors: Hardness, span, tight relaxation, and applications
Nicholas D. Sidiropoulos, Paris Karakasis, Aritra Konar
We consider the problem of finding the smallest or largest entry of a tensor of order N that is specified via its rank decomposition. Stated in a different way, we are given N sets…
PHASED: Phase-Aware Submodularity-Based Energy Disaggregation
Faisal M. Almutairi, Aritra Konar, Ahmed S. Zamzam +1
Energy disaggregation is the task of discerning the energy consumption of individual appliances from aggregated measurements, which holds promise for understanding and reducing ene…
Cell-Edge Detection via Selective Cooperation and Generalized Canonical Correlation
Mohamed Salah Ibrahim, Ahmed S. Zamzam, Aritra Konar +1
Improving the uplink quality of service for users located around the boundaries between cells is a key challenge in LTE systems. Relying on power control, existing approaches throt…
Fast Algorithms for Joint Multicast Beamforming and Antenna Selection in Massive MIMO
Mohamed Salah Ibrahim, Aritra Konar, Nicholas D. Sidiropoulos
Massive MIMO is currently a leading physical layer technology candidate that can dramatically enhance throughput in 5G systems, for both unicast and multicast transmission modaliti…
