高阶奇异值分解(HOSVD)是张量TUCKER分解的一种标准算法。遗憾的是,由于其基于l2规范的公式,TUCKER分解已被证明对数据中的异常值敏感。在本文中,我们首先引入了一种基于l1范数的TUCKER分解的抗离群值变体L1-TUCKER。然后,我们提出了求解L1-TUCKER问题的一种新算法L1-HOSVD。我们的数值研究表明,与HOSVD和其他最先进的方法相比,L1-HOSVD的离群电阻。
Higher-Order Singular-Value Decomposition (HOSVD) is a standard algorithm for TUCKER decomposition of tensors. Regretfully, TUCKER decomposition has been shown to be sensitive against outliers in the data, due to its L2-norm-based formulation. In this paper, we first introduce L1-TUCKER, an outlier-resistant L1-norm-based variant of TUCKER decomposition. Then, we present L1-HOSVD, a novel algorithm for the solution of L1-TUCKER. Our numerical studies illustrate the outlier resistance of L1-HOSVD compared to HOSVD and other state-of-the-art methods.
