Web30 de jul. de 2024 · In this work, we choose a TN with a hierarchical tree structure, called tree TN (TTN). Compared with MPS, TTN is more similar to the deep neural network, since both possess a hierarchical structure. (figure A1 (d)) shows a TTN formed by third-order tensors. This TTN consists of several layers. foam chaise loungeWebIn the hierarchical Tucker format, the sparsity of the representation of a tensor is determined by the hierarchical rank (2) for subsets t from a dimension tree. If one puts the vectors x from (4) into the columns of a matrix (cf.
