A tensor in the context\nof data analysis is a multidimensional array. rTensor does this\nby providing a S4 class 'Tensor' that wraps around the base\n'array' class. rTensor provides common tensor operations as\nmethods, including matrix unfolding, summing/averaging across\nmodes, calculating the Frobenius norm, and taking the inner\nproduct between two tensors. Familiar array operations are\noverloaded, such as index subsetting via '[' and element-wise\noperations. rTensor also implements various tensor\ndecomposition, including CP, GLRAM, MPCA, PVD, Tucker, INDSCAL,\nRESCAL, DEDICOM, PARAFAC2, and 2DLDA. For tensors with 3 modes,\nrTensor also implements transpose, t-product, and t-SVD, as\ndefined in Kilmer et al. (2013). Some auxiliary functions\ninclude the Khatri-Rao product, Kronecker product, and the\nHadamard product for a list of matrices.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Date":
