What a great online book about Data Mining!!! Thanks to the authors for providing this book for free but honestly I would buy the book if it was available in print (now I need to do a lot of printing work).
What is it that makes this book so great? The structure and visualization are what caught my attention. Have a look at the table of content it is actually a Data Mining Map; what a great idea to use structured map.
The authors´ approach is practical and does not go too deep in explanations which is good if you are not interested in the theoretical equations behind the stats. You will find a lot of pictures, tables, definitions and exercises but less formulas. This online book was created by Dr. Saed Sayad in a collaboration with Professor Stephen T. Balke in the Department of Chemical Engineering and Applied Chemistry at the University of Toronto.
