Recursive Robust PCA or Recursive Sparse Recovery in Large but Structured Noise (parts 1 and 2 combined)
Chenlu Qiu, Namrata Vaswani, Brian Lois +1
This work studies the recursive robust principal components analysis (PCA) problem. If the outlier is the signal-of-interest, this problem can be interpreted as one of recursively…

An Online Algorithm for Separating Sparse and Low-dimensional Signal Sequences from their Sum
Han Guo, Chenlu Qiu, Namrata Vaswani
This paper designs and evaluates a practical algorithm, called practical recursive projected compressive sensing (Prac-ReProCS), for recovering a time sequence of sparse vectors $S…

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…
