Simple Regenerating Codes: Network Coding for Cloud Storage
Dimitris S. Papailiopoulos, Jianqiang Luo, Alexandros G. Dimakis +2
Network codes designed specifically for distributed storage systems have the potential to provide dramatically higher storage efficiency for the same availability. One main challen…
Distributed Storage Codes through Hadamard Designs
Dimitris S. Papailiopoulos, Alexandros G. Dimakis
In distributed storage systems that employ erasure coding, the issue of minimizing the total {\it repair bandwidth} required to exactly regenerate a storage node after a failure ar…
Sparse Principal Component of a Rank-deficient Matrix
Megasthenis Asteris, Dimitris S. Papailiopoulos, George N. Karystinos
We consider the problem of identifying the sparse principal component of a rank-deficient matrix. We introduce auxiliary spherical variables and prove that there exists a set of ca…
Repair Optimal Erasure Codes through Hadamard Designs
Dimitris S. Papailiopoulos, Alexandros G. Dimakis, Viveck R. Cadambe
In distributed storage systems that employ erasure coding, the issue of minimizing the total {\it communication} required to exactly rebuild a storage node after a failure arises.…
