WebFeb 3, 2024 · The sequentially truncated HOSVD (STHOSVD) is a more computationally efficient procedure with similar approximation properties (Vannieuwenhoven et al. 2012 ). We provide its pseudocode in Alg. 4. Randomization can be employed to accelerate STHOSVD even further (cf. Che and Wei 2024; Ahmadi-Asl et al. 2024 ).
