IEEE TRANSACTIONS ON INFORMATION THEORY 2018年 第2期64卷 689-703页
作者: Kueng, Richard Jung, Peter Free Univ Berlin Dahlem Ctr Complex Quantum Syst D-14195 Berlin Germany Tech Univ Berlin Commun & Informat Theory Grp D-10587 Berlin Germany
We investigate recovery of nonnegative vectors from non-adaptive compressive measurements in the presence of noise of unknown power. In the absence of noise, existing results in the literature identify properties of t... 详细信息

Inferring large graphs using l1-penalized likelihood (vol 28, pg 905, 2018)
收藏 引用
STATISTICS AND COMPUTING 2018年 第6期28卷 1231-1231页
作者: Champion, Magali Picheny, Victor Vignes, Matthieu Univ Paris 05 Lab MAP5 45 Rue St Peres F-75270 Paris 06 France Univ Paul Sabatier Inst Math Toulouse UMR5219 118 Route Narbonne F-31062 Toulouse 9 France Univ Toulouse INRA MIAT F-31326 Castanet Tolosan France Massey Univ Inst Fundamental Sci Palmerston North New Zealand
We address the issue of recovering the structure of large sparse directed acyclic graphs from noisy observations of the system. We propose a novel procedure based on a specific formulation of the \(\ell _1\)-norm regu... 详细信息
