Recursive Sparse Recovery in Large but Structured Noise - Part 2
Chenlu Qiu, Namrata Vaswani
We study the problem of recursively recovering a time sequence of sparse vectors, St, from measurements Mt := St + Lt that are corrupted by structured noise Lt which is dense and c…

ReProCS: A Missing Link between Recursive Robust PCA and Recursive Sparse Recovery in Large but Correlated Noise
Chenlu Qiu, Namrata Vaswani
This work studies the recursive robust principal components' analysis (PCA) problem. Here, "robust" refers to robustness to both independent and correlated sparse outliers, althoug…

Support-Predicted Modified-CS for Recursive Robust Principal Components' Pursuit
Chenlu Qiu, Namrata Vaswani
This work proposes a causal and recursive algorithm for solving the "robust" principal components' analysis (PCA) problem. We primarily focus on robustness to correlated outliers.…
