PETRELS: Parallel Subspace Estimation and Tracking by Recursive Least Squares From Partial Observations

Many real world datasets exhibit an embedding of low-dimensional structure in a high-dimensional manifold. Examples include images, videos and internet traffic data. It is of great significance to estimate and track the low-dimensional structure with small storage requirements and computational comp...
