Coding Regression trees in 150 lines of R code

André Bleier Blog, Data Science

Motivation There are dozens of machine learning algorithms out there. It is impossible to learn all their mechanics, however, many algorithms sprout from the most established algorithms, e.g. ordinary least squares, gradient boosting, support vector machines, tree-based algorithms and neural networks. At STATWORX we discuss algorithms daily to evaluate their usefulness for a specific project. In any case, understanding these …

Data Science in Python – Der Einstieg in Machine Learning mit Scikit-Learn

Moritz Gnisia Blog, Data Science

In unseren bisherigen Artikeln zu Data Science in Python haben wir uns mit der grundlegenden Syntax, Datenstrukturen, Arrays, der Datenvisualisierung und Manipulation/Selektion auseinander gesetzt. Was jetzt noch für den Einstieg fehlt, ist die Möglichkeit Modelle auf die Daten anzuwenden, um so zum einen Muster in diese zu erkennen und zum anderen Prädiktionen abzuleiten. Die Vielfalt an implementierten Modellen in Python …
