A New Truncation Strategy for the Higher-Order Singular Value Decomposition
A New Truncation Strategy for the Higher-Order Singular Value Decomposition
We present an alternative strategy for truncating the higher-order singular value decomposition (T-HOSVD). An error expression for an approximate Tucker decomposition with orthogonal factor matrices is presented, leading us to propose a novel truncation strategy for the HOSVD, which we refer to as the sequentially truncated higher-order singular value decomposition …
