oai:localhost:PNK-74492023-04-03T08:41:37Z Maximum relative distance between real rank-two and rank-one tensors Henrik, Eisenmann André, Uschmajew Frobenius norm rank-one approximation CC BY It is shown that the relative distance in Frobenius norm of a real symmetric order-d tensor of rank-two to its best rank-one approximation is upper bounded by 1−(1−1/d)d−1−−−−−−−−−−−−−√. This is achieved by determining the minimal possible ratio between spectral and Frobenius norm for symmetric tensors of border rank two, which equals (1−1/d)(d−1)/2. These bounds are also verified for arbitrary real rank-two tensors by reducing to the symmetric case. 2023-04-03T08:41:37Z 2023-04-03T08:41:37Z 2022 Book https://link.springer.com/article/10.1007/s10231-022-01268-w https://dlib.phenikaa-uni.edu.vn/handle/PNK/7449 en application/pdf Springer |
