My name is Holger K. von Jouanne-Diedrich (a.k.a. vonjd) and I am a full professor for Information Management and Customer Relationship Management at the University of Applied Sciences Aschaffenburg in Bavaria, Germany.

I am interested in all kinds of things but all have to do with understanding stuff and learning new stuff. Topics include data science, machine learning, quantitative finance but also science and maths in general and philosophy, especially epistemology and philosophy of religion. Additionally other things that interest me are softer topics like management, psychology and history.

R has been my favorite system for many years and I am also the author of the
OneR Machine Learning package:
