Fast Robust Subspace Tracking via PCA in Sparse Data-Dependent Noise
Praneeth Narayanamurthy, Namrata Vaswani
This work studies the robust subspace tracking (ST) problem. Robust ST can be simply understood as a (slow) time-varying subspace extension of robust PCA. It assumes that the true…
Federated Over-Air Subspace Tracking from Incomplete and Corrupted Data
Praneeth Narayanamurthy, Namrata Vaswani, Aditya Ramamoorthy
In this work we study the problem of Subspace Tracking with missing data (ST-miss) and outliers (Robust ST-miss). We propose a novel algorithm, and provide a guarantee for both the…
Provable Low Rank Phase Retrieval
Seyedehsara Nayer, Praneeth Narayanamurthy, Namrata Vaswani
We study the Low Rank Phase Retrieval (LRPR) problem defined as follows: recover an matrix of rank from a different and independent set of phaseless (mag…
Provable Subspace Tracking from Missing Data and Matrix Completion
Praneeth Narayanamurthy, Vahid Daneshpajooh, Namrata Vaswani
We study the problem of subspace tracking in the presence of missing data (ST-miss). In recent work, we studied a related problem called robust ST. In this work, we show that a sim…
