Organizing SIAM Annual Meeting 2017 Minisymposium: Numerical Linear Algebra in Data Science
Motivated by the extremely large amounts of data streaming from scientific research and daily life, recent years have witnessed exciting developments in the theory and practice of numerical linear algebra for obtaining instantaneous insight from massive datasets. This minisymposium introduces recent advances in both theory and highperformance algorithms for fast numerical linear algebra in data science, e.g. efficient matrix decomposition and applications, fast and scalable algorithms for optimization. These techniques significantly improve the efficiency of existing algorithms for information recovery, statistical learning, and machine learning. Section 1, Section 2.
A MATLAB package ButterflyLab
ButterflyLab is a MATLAB toolbox for fast evaluation of multidimensional Fourier integral operators for wave equations and a class of transforms in harmonic analysis. Algorithms in this package are based on the comprementary lowrank structure of the matrix representations of these opertors and transforms. The butterfly algorithm or butterfly factorization is able to evaluate the matrixvector multiplication with nearly linear operation and memory complexity. This MATLAB package is available at Codes.
