We consider the problem of estimating a low-rank mean matrix when the data matrix is subject to measurement errors as well as gross outliers in some of its entries. The purpose of the paper is to make various algorithms accessible with an understanding of their abilities and limitations to ...
This paper introduces the S1/2-norm for matrices to induce their lower rank, based on which a new model for robust sparse and low-rank matrix decomposition is proposed. To the best of our knowledge, this is the first time that the S1/2-norm for matrices is used to characterize the low...

C++ implementation of thePageRankalgorithm (Google) by Sergey Brin and Lawrence Page and theHITSalgorithm (Ask.com) by Jon Kleinberg, that uses aCSR(Compressed Sparse Row) matrix andmmapto minimize memory usage. This script computes the top-k nodes based on the rankings of the two algorithms,...
