The static method CTD-S outperforms the state of-the-art Tensor-CUR in terms of time, memory usage, and accuracy. The dynamic method CTD-D is the fastest.
S3CMTF-opt shows the lowest time complexity and S3CMTF-base shows the lowest memory usage. For simplicity, we assume that all modes are of size I, of rank J, and an I × K matrix is coupled to one mode
Introduction The truncated Tucker decomposition, also known as the truncated higher-order singular value decomposition (HOSVD), has been extensively utilized as an efficient tool in many applica
Tucker tensor decomposition offers a more effective representation for multiway data compared to the widely used PARAFAC model. However, its flexibility brings the challenge of selecting the appropria
