randomized algorithms for Distributed Nonlinear Optimization Under Sparsity Constraints
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2016年 第6期64卷 1420-1434页
作者: Ravazzi, Chiara Fosson, Sophie M. Magli, Enrico Politecn Torino Dept Elect & Telecommun I-10129 Turin Italy
Distributed optimization in multi-agent systems under sparsity constraints has recently received a lot of attention. In this paper, we consider the in-network minimization of a continuously differentiable nonlinear fu... 详细信息

Randomized Algorithms for Scheduling VMs in the Cloud
收藏 引用
Annual IEEE International Conference on Computer Communications
作者: Javad Ghaderi Electrical Engineering Department Columbia University
We consider the problem of scheduling VMs (Virtual Machines) in a multi-server system motivated by cloud computing applications. VMs arrive dynamically over time and require various amounts of resources (e.g., CPU, Me... 详细信息

International Conference for High Performance Computing, Networking, Storage and Analysis (SC)
作者: Yamazaki, Ichitaro Kurzak, Jakub Luszczek, Piotr Dongarra, Jack Univ Tennessee Dept Elect Engn & Comp Sci Knoxville TN 37996 USA
For data analysis, a partial singular value decomposition (SVD) of the sparse matrix representing the data is a powerful tool. However, computing the SVD of a large matrix can take a significant amount of time even on... 详细信息

SIAM JOURNAL ON SCIENTIFIC COMPUTING 2024年 第2期46卷 A1186-A1213页
作者: Minster, Rachel Li, Zitong Ballard, Grey Wake Wake Forest Univ Winston Salem NC 27109 USA Univ Calif Irvine Irvine CA 92697 USA
The Tucker tensor decomposition is a natural extension of the singular value decomposition (SVD) to multiway data. We propose to accelerate Tucker tensor decomposition algorithms by using randomization and paralleliza... 详细信息
