Video on-demand streaming from Internet-based servers is becoming one of the most important services offered by wireless networks today. In order to improve the area spectral efficiency of video… Expand
FemtoCaching: Wireless video content delivery through distributed caching helpers
- Negin Golrezaei, Karthikeyan Shanmugam, A. Dimakis, A. Molisch, G. Caire
- Computer Science, Mathematics
- Proceedings IEEE INFOCOM
- 19 September 2011
We suggest a novel approach to handle the ongoing explosive increase in the demand for video content in wireless/mobile devices. We envision femtocell-like base stations, which we call helpers, with… Expand
XORing Elephants: Novel Erasure Codes for Big Data
- M. Sathiamoorthy, Megasthenis Asteris, +4 authors D. Borthakur
- Computer Science, Mathematics
- Proc. VLDB Endow.
- 16 January 2013
Distributed storage systems for large clusters typically use replication to provide reliability. Recently, erasure codes have been used to reduce the large storage overhead of three-replicated… Expand
Compressed Sensing using Generative Models
- Ashish Bora, A. Jalal, E. Price, A. Dimakis
- Mathematics, Computer Science
- ICML
- 9 March 2017
The goal of compressed sensing is to estimate a vector from an underdetermined system of noisy linear measurements, by making use of prior knowledge on the structure of vectors in the relevant… Expand
Femtocaching and device-to-device collaboration: A new architecture for wireless video distribution
- Negin Golrezaei, A. Molisch, A. Dimakis, G. Caire
- Computer Science, Mathematics
- IEEE Communications Magazine
- 7 April 2012
We present a new architecture to handle the ongoing explosive increase in the demand for video content in wireless networks. It is based on distributed caching of the content in femtobasestations… Expand
A Survey on Network Codes for Distributed Storage
- A. Dimakis, K. Ramchandran, Y. Wu, Changho Suh
- Computer Science, Mathematics
- Proceedings of the IEEE
- 26 April 2010
Distributed storage systems often introduce redundancy to increase reliability. When coding is used, the repair problem arises: if a node storing encoded information fails, in order to maintain the… Expand
Decentralized erasure codes for distributed networked storage
- A. Dimakis, V. Prabhakaran, K. Ramchandran
- Computer Science, Mathematics
- IEEE Transactions on Information Theory
- 1 June 2006
In this correspondence, we consider the problem of constructing an erasure code for storage over a network when the data sources are distributed. Specifically, we assume that there are n storage… Expand
Gradient Coding: Avoiding Stragglers in Distributed Learning
- R. Tandon, Qi Lei, A. Dimakis, Nikos Karampatziakis
- Computer Science
- ICML
- 17 July 2017
We propose a novel coding theoretic framework for mitigating stragglers in distributed learning. We show how carefully replicating data blocks and coding across gradients can provide tolerance to… Expand
