Explicit and implicit tensor decomposition-based algorithms and applications (2019)
Abstract / truncated to 115 words
Various real-life data such as time series and multi-sensor recordings can be represented by vectors and matrices, which are one-way and two-way arrays of numerical values, respectively. Valuable information can be extracted from these measured data matrices by means of matrix factorizations in a broad range of applications within signal processing, data mining, and machine learning. While matrix-based methods are powerful and well-known tools for various applications, they are limited to single-mode variations, making them ill-suited to tackle multi-way data without loss of information. Higher-order tensors are a natural extension of vectors (first order) and matrices (second order), enabling us to represent multi-way arrays of numerical values, which have become ubiquitous in signal processing and ... toggle 8 keywordshigher-order tensor – tensor decomposition – multilinear algebra – numerical linear algebra – optimization – blind source separation – blind system identification – pattern recognition
