Title: Useless
Product review: My goal when I purchased this book was to learn the fundametal techniques and algorithms of data mining, such as C4.5/C5.0 and other popular algorithms, after reading the book my goal is far from being reached, on the one hand the book is not will structured, it covers many topics but with a very weak logical connection among them, on the other hand there's no complete and simple example that take the reader from A to Z illustrating step by step the basic concepts of reducing entropy, rules productions and pruning etc..., finally there's no design explanation of the downloadable code that can give a global view of the "software" architecture and it's building blocks, leaving the reader confused and wishing he saved he's money!.
