| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We robustify simultaneous low rank approximation of tensors (SLRAT) for the dimensionality reduction of tensor data including outliers, and call it robust SLRAT. It is experimentally shown that the robust SLRAT achieves lower reconstruction error than the conventional SLRAT when a dataset contains outliers. We also propose a method for classifying sets of tensors and call it the subspace matching, where both training data and testing data are represented by their subspaces, and each testing datum is classified on the basis of the similarity between subspaces. It is experimentally verified that the robust SLRAT achieves higher recognition rate than the conventional SLRAT when the testing data contain outliers. |
