On Approximation Algorithm for Orthogonal Low-Rank Tensor Approximation
Yuning Yang
The goal of this work is to fill a gap in [Yang, SIAM J. Matrix Anal. Appl, 41 (2020), 1797--1825]. In that work, an approximation procedure was proposed for orthogonal low-rank te…

Half-Quadratic Alternating Direction Method of Multipliers for Robust Orthogonal Tensor Approximation
Yuning Yang, Yunlong Feng
Higher-order tensor canonical polyadic decomposition (CPD) with one or more of the latent factor matrices being columnwisely orthonormal has been well studied in recent years. Howe…
