Tensor observations are assumed to be generated from a Kronecker-structured dictionary multiplied by sparse coefficient tensors that follow the separable sparsity model. This paper provides sufficient conditions on the underlying coordinate dictionaries, coefficient and noise distributions, and number of ...
Finally, we design Tree-structured Kronecker Convolutional Networks (TKCN) which employs Kronecker convolution and TFA module. Extensive experiments on three datasets, PASCAL VOC 2012, PASCAL-Context and Cityscapes, verify the effectiveness of our proposed approach. We make the code and the trained ...
科研裁缝。民族主义 大规模结构化矩阵的逆矩阵的低秩张量表示 | Provable Low-Rank Tensor-Train Approximations in the Inverse of Large-Scale Structured Matrices 一类大规模的具有一定结构性的满秩矩阵,它是由一些小规模矩阵的Kronecker乘积叠加得到。这类矩阵如果在更高维的空间用张量表达,则具有低秩表示。那么这类...

This enables the tracking of the real-valued tensor-based subspace estimate via a similar Kronecker-structured projection applied to the real-valued matrix-based subspace estimate. In time-varying multidimensional harmonic retrieval problems, the TeTraKron-based subspace tracking schemes outperform the ...
