Abstract: We consider computing the QR factorization with column pivoting (QRCP) for a tall and skinny matrix, which has important applications including low-rank approximation and rank determination.

Abstract: Surface charge accumulation on insulators is one of the bottlenecks for the development of DC electric power system. This paper studies a ±200 kV DC basin-type insulator designed for GIL ...

Positive definite matrices are widely used in machine learning and probabilistic modeling, especially in applications related to graph analysis and Gaussian models. It is not uncommon that positive ...
