This is an outstanding book and by far the best machine learning book of the several I have read. I highly recommend.1) The author writes this in a way that you can perform machine learning tasks in R without any prior experience using R or ML. He gets you up to speed quickly on how to download R Studio and explains everything you need to know about R in order to perform the ML tasks that are described later in the book. He doesn't explain all of the things you can do in R as in many other books, because you don't necessarily need to know everything about R to perform ML tasks and this book is about ML. So this is obviously not a book that is exhaustive of everything possible in R.2) The structure of this book is outstanding and very logical. Within each of the chapters on Machine Learning models, he describes the model and how it works, includes a section covering the model's syntax in R, the strengths and weaknesses of each model, compares the model to the prior models discussed, and then uses that foundation to walk you through an example of applying each model to real data. Within the examples, he uses the 5 steps of a modeling process: 1) collecting data, 2) exploring and prepping the data, 3) training the model, 4) evaluating model performance, and 5) Improving model performance. I love this structure!3) His explanations of everything are outstanding. I've read several ML books and he by far is the best at explaining things in a way that people can clearly understand. If the model involves statistical concepts, he explains what you need to know very well.4) The book covers many ML models: K-Nearest Neighbors, Naive Bayes, Decision Trees, Classification Rules, Regression, Regression Trees, Model Trees, Neural Networks, Support Vector Machines, Association Rules, K-Means Clustering, and Random Forests. For an advanced Data Scientist, this may not seem like an exhaustive list. However, I feel that for a beginning data scientist or someone that is just interested in getting a good overview of data modeling, I feel this is a great choice of model coverage.Bottom line- if you're at all interested in machine learning in R, this is the book to get. If you're already an advanced data scientist with years of experience, this may not be the best text for you, though.

Most other books I know on this topic are far too theoretical for me.Brett provides a very practical approach.

Excellent book. I have come across one of the best books so far on Machine Learning using R. The author has made sure that the book is readable for both for a new users of R programming as well as who are new to machine learning with multiple case studies. This is also a great book for people who want to refresh their memories in key techniques of machine learning. I am an experience data science professional and I would recommend this book to readers looking to understand how to build machine learning models using R. Thanks to author for writing this book.

Puede resultar chocante, como poco, ver que alguien califica de «entretenido» un libro más bien técnico como éste, pero resulta que el calificativo es bastante apropiado. Lo es porque Brett lantz ha escrito una obra muy bien estructurada y pedagógicamente escrita sobre un tema que a muchos puede resultar intimidatorio, pero que él se las ingenia para volver atractivo.El libro es una introducción amable y facilitada a catorce algoritmos de «Machine Learning» (expresión que suele traducirse al castellano como «aprendizaje automático»), una muestra representativa, aunque desde luego no exhaustiva, de los métodos de Machine Learning en circulación. Los catorce algoritmos cubren desde k-nearest neighbors hasta Random Forests, pasando por Decision trees y Association rules. Los distintos algoritmos (de aprendizaje supervisado, no supervisado y de meta-aprendizaje) cubren cuatro tipos de tareas: clasificar, predecir, detectar patrones y agrupar.Aunque ya tenía noticia de ello, me parece digno de ser resaltado que los algoritmos más potentes, como Artificial Neural Networks o Support Vector Machines, son lo que Lantz llama «algoritmos de caja negra»: sabemos que funcionan bien pero no sabemos por qué funcionan bien.Uno de los problemas frecuentes con este tipo de libros es que hay complementos que tienes que bajar de Internet y que no siempre se comportan como deberían. En este caso, ¡loado sea el cielo!, no es así: las bases de datos y el código escrito en el lenguaje R funcionan sin problemas. Sólo en los tres últimos capítulos me he llevado algún tropezón. Especialmente en el último, que es con diferencia el de contenido más avanzado: computación en la nube, big data y demás.Pero, a pesar de lo que acabo de decir, se aprende mucho con este texto, dado el esmero que pone el autor en explicar todos los detalles (como las líneas de código que pudieran resultar más intrigantes) y en no dejar a nadie atrás.En suma, una excelente iniciación a Machine Learning usando el software R, el más empleado por los estadísticos, aunque no el más común en aprendizaje automático.

I am a complete beginner to R as well as Machine learning, this book has clearly stated every concept and made me understand machine learning even better. I highly recommend this book
