Decomposition Methods for Large Scale LP Decoding
LP Decoding Alternating Direction Method of Multipliers Information Theory
2012/4/18
When binary linear error-correcting codes are used over symmetric channels, a relaxed version of the maximum likelihood decoding problem can be stated as a linear program (LP). This LP decoder can be ...
Efficient variational inference in large-scale Bayesian compressed sensing
large-scale Bayesian variational inference Computer Vision and Pattern Recognition
2011/10/9
Abstract: We study linear models under heavy-tailed priors from a probabilistic viewpoint. Instead of computing a single sparse most probable (MAP) solution as in standard deterministic approaches, th...
Distributed SIR-Aware Scheduling in Large-Scale Wireless Networks
Distributed SIR-Aware Large-Scale Wireless Networks Information Theory
2011/8/31
Abstract: Opportunistic scheduling and routing can in principle greatly increase the throughput of decentralized wireless networks, but to be practical they must do so with small amounts of timely sid...
