Acknowledgments
Third Edition of the Book
We would like to express our grateful thanks to all of the previous and current members of the Data Mining
Group at UIUC, the faculty and students in the Data and Information Systems (DAIS) Laboratory in the
Department of Computer Science at the University of Illinois at Urbana-Champaign, and many friends and
colleagues, whose constant support and encouragement have made our work on this edition a rewarding
experience. We would also like to thank students in CS412 and CS512 classes at UIUC of the 2010–2011
academic year, who carefully went through the early drafts of this book, identified many errors, and suggested
various improvements.
We also wish to thank David Bevans and Rick Adams at Morgan Kaufmann Publishers, for their enthusiasm,
patience, and support during our writing of this edition of the book. We thank Marilyn Rash, the Project
Manager, and her team members, for keeping us on schedule.
We are also grateful for the invaluable feedback from all of the reviewers. Moreover, we would like to thank
U.S. National Science Foundation, NASA, U.S. Air Force Office of Scientific Research, U.S. Army Research
Laboratory, and Natural Science and Engineering Research Council of Canada (NSERC), as well as IBM
Research, Microsoft Research, Google, Yahoo! Research, Boeing, HP Labs, and other industry research labs
for their support of our research in the form of research grants, contracts, and gifts. Such research support
deepens our understanding of the subjects discussed in this book. Finally, we thank our families for their
wholehearted support throughout this project.
