Speaker — David Hong (Department of Statistics and Data Science, University of Pennsylvania, Philadelphia, PA, US) Abstract — Principal component analysis (PCA) is a workhorse method for identifying low-dimensional (i.e., low-rank) structure in noisy data and is ubiquitous in signal processing. However, it estimates the underlying low-rank structure sub-optimally when the samples have heterogeneous quality, […]
