Dr. Anil Maheshwari has done a great job in taking a complex, highly important subject area and making it accessible to everyone. The book begins by simply connecting to what you know, and then bang - you've suddenly found out about Decision Trees, Regression Models and Artificial Neural Networks, not to mention cluster analysis, mining and Big Data. It takes real experience and authority, as well as a great generosity of spirit to be able to write like this. For instance in Chapter 12 on Big Data, Dr. Maheshwari presents "The Big Data Landscape" that gives you a great overview on a single page. I also much appreciated the way the Primer sections are made available, for beginners, and there is also a way for more advanced readers to get to stuff that is useful to take them to the next level.
