This paper proposes a novel method for classification using rank-1 tensor projection via regularized regression to directly map tensor example to its corresponding label, which is different from the general procedure of classification on the compact representation of the original data. Action can be ...
PyTorch Rank: Understanding PyTorch Rank=-1当我们谈论PyTorch Rank时,我们在讨论什么呢?PyTorch是一个广泛使用的深度学习框架,而Rank是一个指示数据分布广度或深度特征的指标。在PyTorch中,Rank指代的是张量(Tensor)的维度大小。张量是PyTorch中用于储存和操作数据的多维数组。当我们在处理大量数据或是设计复杂的神经网...

In this paper we discuss a multilinear generalization of the best rank-R approximation problem for matrices, namely, the approximation of a given higher-order tensor, in an optimal least-squares sense, by a tensor that has prespecified column rank value, row rank value, etc. For matrices, the...
sparsity needs to be imposed on the rank-1 term so that one can associate cancer versus no cancer with a small group o(genes)and this results in the best sparse rank-1 approximation to a higher-order tensor [12] .Now, the sparsity strategy is a popular technology in such as signal pro...

Recently the problem of determining the best, in the least-squares sense, rank-1 approximation to a higher-order tensor was studied and an iterative method that extends the well-known power method for matrices was proposed for its solution. This higher-order power method is also proposed for ...
