Learning Data Science: Predictive Maintenance with Decision Trees


Predictive Maintenance is one of the big revolutions happening across all major industries right now. Instead of changing parts regularly or even only after they failed it uses Machine Learning methods to predict when a part is going to fail.

If you want to get an introduction to this fascinating developing area, read on!

Learning Path for “Data Science with R” – Part I


Over the course of the last two and a half years, I have written over one hundred posts for my blog “Learning Machines” on the topics of data science, i.e. statistics, artificial intelligence, machine learning, and deep learning.

I use many of those in my university classes and in this post, I will give you the first part of a learning path for the knowledge that has accumulated on this blog over the years to become a well-rounded data scientist, so read on!

The Small Data Rule: Infer the Big Picture from only Five Values!


Everybody is talking about big data but the real skill lies in the art of inferring useful information from only a handful of values!

If you want to learn how to determine the range of the typical value of a dataset (i.e. the median) with just five values and why this works, read on!
