Principal Tensor Analysis on k modes CRAN Task View: ChemPhys (http://CRAN.R-project.org/view=ChemPhys) CRAN Task View: MedicalImaging (http://CRAN.R-project.org/view=MedicalImaging) CRAN Task View: Multivariate (http://CRAN.R-project.org/view=Multivariate) CRAN Task View: Psychometrics (http://CRAN.R-project.org/view=Psychometrics) A multiway method to decompose a tensor (array) of any order, as a generalisation of SVD also supporting non-identity metrics and penalisations. 2-way SVD with these extensions is also available. The package includes also some other multiway methods: PCAn (Tucker-n) and PARAFAC/CANDECOMP with these extensions.
