Cílem předmětu je seznámit posluchače se základními pojmy numerické lineární algebry, které se objevují v metodách pro datovou vědu a informatiku. Po úvodu a přehledu maticových reprezentací dat a základních maticových
rozkladů jsou tyto koncepty ilustrovány v různých aplikacích včetně komprese dat, klastrování, klasifikace a neuronových sítí. Kurz si klade za cíl ilustrovat tyto koncepty pomocí softwarové implementace a seznámení s nástroji pro
výpočetní clustery.

The main goal of the course is to understand basic concepts of numerical linear algebra and where such computations arise in data science applications. The focus is on developing an understanding of the mathematical foundation of techniques in informatics and data science and informatics. The goal is also to gain practical experience via basic programming examples and to become familiar with recent research topics in the area. Poslední úprava: Carson Erin Claire, Ph.D. (05.02.2020)
