Web15 de jan. de 2013 · Abstract. We derive and analyse a scheme for the approximation of order d tensors A ∈ R n 1 × ⋯ × n d in the hierarchical ( H -) Tucker format, a dimension-multilevel variant of the Tucker format and strongly related to the TT (tensor train) format. For a fixed rank parameter k, the storage complexity of a tensor in H -Tucker format is O ... Webcompact RNN models with fully decomposed hierarchical Tucker (FDHT) structure. As shown in Figure 1, our pro-posed FDHT-structure RNN models have two main fea-tures. First, Hierarchical Tucker (HT) decomposition [7], a little explored but powerful tool for capturing and model-ing the correlation and structure in high-dimensional data,
