The Success Paradox: Why even a little Bit of Luck often beats Skill
The skill-vs-luck debate never ceases to fascinate. Is it mainly skill, experience, hard work, and the “right” mindset that determines who is becoming successful, rich, or famous, or is it largely luck and fortunate circumstances? In this post, we will conduct an illuminating simulation to show that even a small amount of luck can make all th...

OneR – fascinating insights through simple rules
We already saw the power of the OneR package in the preceding post. Here we want to give some more examples to gain some fascinating, often counter-intuitive, insights. Shirin Glander of Muenster University tested the OneR package with data from the World Happiness Report to find out what makes people happy: https://shiring.github.io/machine_lea...

Why R for data science – and not Python?
There are literally hundreds of programming languages out there, e.g. the whole alphabet of one letter programming languages is taken. In the area of data science there are two big contenders: R and Python. Now why is this blog about R and not Python? I have to make a confession: I really wanted to like Python. I dug deep into the language and so...

Intuition for principal component analysis (PCA)
Principal component analysis (PCA) is a dimension-reduction method that can be used to reduce a large set of (often correlated) variables into a smaller set of (uncorrelated) variables, called principal components, which still contain most of the information. PCA is a concept that is traditionally hard to grasp so instead of giving you the n’th...

Learning R: A gentle introduction to higher-order functions
Have you ever thought about why the definition of a function in R is different from many other programming languages? The part that causes the biggest difficulties (especially for beginners of R) is that you state the name of the function at the beginning and use the assignment operator – as if functions were like any other data type, like vect...

Your AI journey… and Happy Holidays!
I want to draw your attention to a very valuable (and short!) whitepaper from my colleague, Professor Andrew Ng, where he shares important insights on how to lead companies into the AI era. The five steps outlined in the paper are: Execute pilot projects to gain momentum Build an in-house AI team Provide broad AI training Develop an AI strategy ...

Clustering the Bible
During this time of year there is obviously a lot of talk about the Bible. As most people know the New Testament comprises four different Gospels written by anonymous authors 40 to 70 years after Jesus’ supposed crucifiction. Unfortunately we have lost all of the originals but only retained copies of copies of copies (and so on) which date back...
