Essential Math for Data Science E-Learning Training 

Wiskunde vormt het fundament voor Machine Learning-algoritmen en Data Science, noodzakelijk voor het werken en onderzoek op het gebied van Data Science. Veel Data Science-elementen zijn afhankelijk van wiskundige concepten zoals waarschijnlijkheid, statistiek, calculus, lineaire algebra, enzovoort. Daarom is het belangrijk voor datawetenschappers om de principes van deze concepten te begrijpen en hoe deze principes hun modellen en dagelijkse taken kunnen beïnvloeden.

In deze Essential Math for Data Science Learning Kit verken je belangrijke wiskundige concepten die de basis vormen voor Machine Learning-algoritmen, Data Science en Artificial Intelligence.
