Data Mining - Practical Machine Learning Tools and Techniques

This book gets you ready on Machine learning and then goes on to showing you how to implement it using the Java WEKA framework.  If you are a weka user, this is perhaps the only book out there. When I started working with weka this book was helpful. WEKA framework is really good and you know how to work with ARFF format for representing data.
