Description

Mastering Machine Learning Algorithms, Second Edition helps you harness the real power of machine learning algorithms in order to implement smarter ways of meeting today's overwhelming data needs. This newly updated and revised guide will help you master algorithms used widely in semi-supervised learning, reinforcement learning, supervised learning, and unsupervised learning domains. You will use all the modern libraries from the Python ecosystem – including NumPy and Keras – to extract features from varied complexities of data. Ranging from Bayesian models to the Markov chain Monte Carlo algorithm to Hidden Markov models, this machine learning book teaches you how to extract features from your dataset, perform complex dimensionality reduction, and train supervised and semi-supervised models by making use of Python-based libraries such as scikit-learn. You will also discover practical applications for complex techniques such as maximum likelihood estimation, Hebbian learning, and ensemble learning, and how to use TensorFlow 2.x to train effective deep neural networks. By the end of this book, you will be ready to implement and solve end-to-end machine learning problems and use case scenarios.

The book covers a lot of methods, as can be seen in the table of contents. This provides a nice breadth. What is really nice, is that before getting into any of the methods, the author starts with a chapter on ML Model Fundamentals. In this chapter, he presents not just the how's but also the why's of scaling data before modeling. He also talks about model capacity, bias and variance of an estimator, and how these relate to under or over fitting a model. Recently, I have heard two things during presentations: 1) "I won't go over scaling, because I think we all know when to apply these transformations" 2) "I don't even know what you're talking about" when asked about a bias/variance trade-off. I think it's great to have the opportunity to read a practitioner's explanation of these matters. He also talks about the options for splitting a data set into portions: 1) training, validation, and test portions, or 2) just into training and test portions, or 3) using a cross-validation approach. I have taken an ML class on Coursera where the first option was used, and the others weren't mentioned. It's nice to see all three here. He helps the reader by noting that some topics he's introducing will be discussed in more detail in the next few chapters. That's nice because questions start arising in your head, and then you read that and know there's more detail and answers coming, so just relax, and look forward.There are nice plots and Python code snippets throughout. It's helpful that each chapter ends with a summary and list of references.A lot of times we hear "supervised" or "unsupervised". It's nice that the book has three chapters on "semi-supervised" learning. In the Graph-Based Semi-Supervised Learning chapter, there is a "t-distributed stochastic neighbor embedding" (t-SNE) example, which is a topic I was curious about.

I look at algorithms like appliances in a department store. Each has a particular use-case and purpose. For instance, depending on your individual needs while shopping for appliances most often stop to glance at the specs then at the cost to see if a particular unit suits their needs.Few ever think to build the appliance from scratch but rather by one already made to serve their needs progressively adopting it as an augmentation to everyday life. Even easier is when these items can be cataloged in one place, shopped, and put into use immediately (think Sears catalog of 1888). In its first catalog, Sears sold jewelry and watches. The directories grew in popularity, and with time different products were added and tested, even whole houses!While algorithms are not a new thing, thanks to the father of algebra: Abdullah Muhammad bin Musa al-Khwarizmi, it should NOT be challenging to catalog them. This book one of the best, like it, does that facilitating faster solutioning to get to the point of solving problems using built appliances (machine intelligence: algorithms).

Our exciting field of data science (DS) is exploding, and it’s hard to keep up with all of it. We each become extremely focused on our specific work in our current roles, and we are each funneled into specialized areas to solve specific challenges. After a long battle to deliver your great DS tool to production, your next challenge arrives. It seems this problem will require a DS method that you haven’t used since college. Maybe you’re not even sure, which DS method will best address your problem. Regardless, once you decide on a method of modeling, you have limited time to master it. You still need to collect, refine, and condition your data for that method. You must also master how to fight through the training of your chosen model. You’d seek help from your fellow DS’s, but they’re in the situation you just left.Now enters Giuseppe Bonaccorso - a DS friend with a corpus of DS methods that provide adequate mathematical overviews, explanations, and python code applied to substantial examples to get you up to speed quickly. I believe in keeping multiple sources at hand for learning / reviewing any methods. In that spirit, I'm relieved to have Giuseppe's book in my library. In a mere 750+ pages, he takes you on a tour of important methods that, while they won't make you an expert in the foundational mathematics for each method, they won't leave you blind in those respects either. I especially appreciate the references to foundational papers for each method following every group of methods for when we might need or want to go deeper. If you estimate that your library could be enhanced by such a substantial book as I've described, I believe you'd be well benefited by Giuseppe's book. He even manages to provide a good review of reinforced learning that, in my opinion, is extremely challenging to teach clearly.An important note is that this book does not cover natural language processing. In my experience, NLP would require another 750+ pages if it were to be covered as well as the methods that Giuseppe has covered. However, this is the only major field that he skips, and he does relate areas of that field to the techniques that he covers.

I have used this book (1st and 2nd edition) in my Machine Learning class for a couple of years. Together with the Raschka and Mirjalili book (Python Machine Learning), Bonnacorso's provides a solid foundation for understanding the key algorithms, how they work, and how to fine-tune them. Both amanuals re required in my class and my students have only had positive feedback about both books. They are complementary as Bonnacorso does not cover some topics such as Natural Language Processing compared with Raschka, for instance.

As Giuseppe Bonaccorso expresses in this book, "It's always possible to join scientific rigor with an artistic approach." This book offers a great resource to dust off those concepts for the advance practitioners or to learn the fundamentals for those willing to master their ML algorithms artistically.I've been reading this book for over a week by now, and I like how Giuseppe explains important theoretical concepts related to machine learning models, bias, variance, overfitting, underfitting, data normalization, scaling, and so on.Even though this book requires a solid knowledge of essential machine learning topics and familiarity with Python programming language, don't be discouraged. I found out that this book provides the best first-hand experiential advice that someone can provide for someone willing to learn. Moreover, given the complexity of some subjects, proper mathematical training is desirable, but the willingness to learn outweighs it.If you are looking to get great advice and insights from an expert, this book is for you. My recommendation is not to rush over the concepts. As I am reading --still not finished since it's 800 pages, it makes me reflect on my problem-solving styles and helps me identify areas of opportunity for improvement.I have to thank Giuseppe for taking his time to think, sort his thoughts, write, and for sharing his knowledge and experiences for us to become better practitioners.
