I studied this book during my Ph.D. in Computer Science.Tom Mitchel provides a very concise approach to machine learning but exploring various models and techniques and exposes you to what Learning is ; machine learning is described in terms of mathematics .I love how various examples in the book describe things in solid Math and statistical information.Great Chapters on Decision tree, Bayesian Learning, etc,...It is just a joy to be able to find one of my favorite books and be able to read it againThe Material is definitely timeless and applies well to current State of the art in Machine Learning as well.Highly recommend it if you can find a copy, you should have one in your home if you are interested in this subject.The version I received was free of any marks , looked fresh and although I had a hard copy in the past (that I had lost ) and this one is soft cover, paper is good quality .Delivery was also good and on time.
