Tensor Valued Common and Individual Feature Extraction: Multi-dimensional Perspective

  title={Tensor Valued Common and Individual Feature Extraction: Multi-dimensional Perspective},
  author={Ilia Kisil and Giuseppe Giovanni Calvi and Danilo P. Mandic},
  journal={arXiv: Signal Processing},
A novel method for common and individual feature analysis from exceedingly large-scale data is proposed, in order to ensure the tractability of both the computation and storage and thus mitigate the curse of dimensionality, a major bottleneck in modern data science. This is achieved by making use of the inherent redundancy in so-called multi-block data structures, which represent multiple observations of the same phenomenon taken at different times, angles or recording conditions.

Breaking the Curse of Dimensionality for Coupled Matrix-Tensor Factorization

This paper presents a methodological approach, using the Joint dImensionality Reduction And Factors rEtrieval (JIRAFE) algorithm for joint factorization of high-order tensor and matrix, which reduces the high- order CMTF problem into a set of 3-order CMTF and canonical polyadic decomposition (CPD) problems.
