It doesn't seem like a "stripped down version of AIMA" at all, IMHO. AIMA is an AI book, this is an introductory data mining book. As such, this book talks about algorithms for clustering, classification, feature identification, collaborative filtering, etc., none of which are really addressed in depth in AIMA. There is a relatively brief section on learning techniques in AIMA, but it doesn't go into much depth, and is more focused on reinforcement learning than on typical data mining techniques (automatic classification, clustering, etc.)
