Principal component analysis and classification of discrete and mixed feature datasets using Gaussian copula
… a scale invariant and data contamination robust principal component analysis (PCA) for discrete datasets that was further extended to ordinal categorical datasets. This method solves the scale variant and outlier sensitive problem of the usual PCA, and enables us to perform a …

Algorithms and Theory for Robust PCA and Phase Retrieval
… The first part focuses on the problem of \emph{robust principal component analysis} (PCA), which aims to recover an unknown low-rank matrix from a corrupted and partially-observed matrix. </p> <p>The robust PCA problem, originally nonconvex itself, has been solved via a convex relaxation based …
