Reversible MCMC on Markov equivalence classes of sparse directed acyclic graphs
Sparse graphical model Reversible Markov chain Markov equivalence class
2016/1/25
Graphical models are popular statistical tools which are used to represent dependent or causal complex systems. Statistically equivalent causal or directed graphical models are said to belong to a Mar...
Network coding can significantly improve the transmission rate of communication networks with packet loss compared with routing. However, using network coding usually incurs high computational and sto...
Vanilla Lasso for sparse classification under single index models
Vanilla Lasso sparse classification single index models
2016/1/20
This paper study sparse classification problems. We show that under single-index models, vanilla Lasso could give good estimate of unknown parameters. With this result, we see that even if the model i...
SBA-term: Sparse Bilingual Association for Terms
SBA-term Sparse Bilingual Association Terms
2016/1/19
Bilingual semantic term association is very use-ful in cross-language information retrieval, statistical machine translation, and many other applications in natural language processing. In this paper,...
Detailed Network Measurements Using Sparse Graph Counters: The Theory
Measuring the network traffic network counter memory storage counters
2015/8/21
Measuring network flow sizes is important for tasks like accounting/billing, network forensics and security. Per-flow accounting is considered hard because it requires that many counters b...
Smooth compression, Gallager bound and Nonlinear sparse-graph codes
Data compression data smoothness coding
2015/8/21
A data compression scheme is defined to be smooth if its image (the codeword) depends gracefully on the source (the data). Smoothness is a desirable property in many practical contexts, and widely use...
Stable Recovery of Sparse Overcomplete Representations in the Presence of Noise
Sparse representation Overcomplete Representation
2015/8/21
Overcomplete representations are attracting interest in signal processing theory, particularly due
to their potential to generate sparse representations of signals. However, in general, the problem o...
For high dimensional supervised learning problems, often using problem specific assumptions can lead to greater accuracy. For problems with grouped covariates, which are believed to have sparse effect...
