Title of Lecture:

Tensor Decompositions for Multidimensional Signal Processing

Abstract: I will give an introductory tutorial on techniques to address problems of storing and/or multilinear processing of very large multidimensional data arrays (tensors). Such "big data" could possibly result from multi-sensor measurements. After introducing basic tensor operations, I will cover both theoretical and computational aspects of two classic tensor decompositions: Canonical Polyadic Decomposition (CPD) and Tucker Decomposition (TD). I will also introduce the concept of Tensor Networks, with particular emphasis on the relatively recent Tensor Train Decomposition (TTD).
