Low-rank and sparsityTowards the goal of improving acoustic modeling for automatic speech recognition (ASR), this work investigates the modeling of senone subspaces in deep neural network (DNN) posteriors using low-rank and sparse modeling approaches. While DNN posteriors are typically very high-...
论文笔记-IGCV3:Interleaved Low-Rank Group Convolutions for Efficient Deep Neural Networks 2018年07月11日 14:05:46 Liven_Zhu 介绍 在这篇论文中,作者同时使用低秩核和稀疏核(low-rank and sparse kernel)来组成一个密集kernel。基于ICGV2的基础上,作者提出了ICGV3。 近几年,卷积网络在计算...
rank and sparse constraints, both the global subspaces and local geometric structures of data are captured by the reconstruction coefficient matrix and at the same time the low-dimensional embedding of data are enforced to respect the low-rankness and sparsity. In this way, the reconstruction ...

We consider the problem of estimating high-dimensional covariance matrices of a particular structure, which is a summation of low rank and sparse matrices. This covariance structure has a wide range of applications including factor analysis and random effects models. We propose a Bayesian method of ...

Low-rank or sparse tensor recovery finds many applications in computer vision and machine learning. The recently proposed regularized multilinear regression and selection (Remurs)model assumes the true tensor to be simultaneously low-Tucker-rank and sparse, and has been successfully applied in fMRI ...
A low-rank and sparse matrix decomposition (LRaSMD) detector has been proposed to detect anomalies in hyperspectral imagery (HSI). The detector assumes background images are low-rank while anomalies are gross errors that are sparsely distributed throughout the image scene. By solving a constrained...
