Complex and Quaternionic Principal Component Pursuit and Its Application to Audio Separation

no code implementations9 Jan 2018 Tak-Shing T. Chan, Yi-Hsuan Yang

Thus, in this letter, we extend principal component pursuit to the complex and quaternionic cases to account for the missing phase information.

Polar $n$-Complex and $n$-Bicomplex Singular Value Decomposition and Principal Component Pursuit

no code implementations9 Jan 2018 Tak-Shing T. Chan, Yi-Hsuan Yang

Informed by recent work on tensor singular value decomposition and circulant algebra matrices, this paper presents a new theoretical bridge that unifies the hypercomplex and tensor-based approaches to singular value decomposition and robust principal component analysis.
