The book is a comprehensive guide to machine and deep learning using the Python language. It serves as both a step-by-step tutorial and a reference that you will constantly return to during the construction of machine learning systems. The book is filled with clear explanations, visual representations, working examples and reveals in detail all important machine learning techniques. While some books teach you to follow the instructions, Raszka and Mirjalili lay out the principles behind machine learning, allowing you to build your own models and applications.
