Mandatory read for school, did not finish around 20%.
The chapters are easy to follow. The chapter on Data preprocessing was very valuable to me, explaining why it's so important and which (statistical) methods could be used. Unfortunately the way the results were being obtained (old version of SPSS) were not so relevant for me since in this course I have to use Python. It does seem like a good book to learn how Data Mining algorithms work and how to interpret its results.
Really got me interested in the domain of data mining. It is rather an old book and I would have liked some more hands-on examples in a more modern mining tool. Nevertheless, worth the read.
