Heiko Wagner
Bonn
Hello and Welcome at thebigdatablog.com. My name is Heiko Wagner and this Website is about stuff which is somewhat related to my research. However, this website has a different focus. While my research is mostly about theoretical properties of various estimators, this website is focussed on implementation details, in particular if we are facing a large amount of data. Beside I also want to present different projects I carried out in my spare time to a larger audience.

Reccomandations by the author
Books i like
The Elements of Statistical Learning
This book gives a good overview at various machine learning techniques. It lacks of a deeper theoretical foundation and proofs, but can be considered as the best entry point for beginners.
Introductory Real Analysis
Still my favorite math book. This book requires no prior knowledge and is a very good introduction of the underling basic concepts that eventually lead to probability theory.
Markov Chains
A clear and mathematically exact introduction to markov chains.
Functional Data Analysis
An excellent and fun to read introduction into the field of functional data analysis. Lack of proofs and a deeper theoretical foundation, also perhaps a bit outdated, but still one of the best books to start with.recently added
