Machine training: design of signs. Principles and techniques for analysts. Kazari Amanda, Zhen Alice

The construction of signs is an extremely important stage in the process of machine learning, but this topic is rarely discussed separately. With the help of this book, you will learn how to extract and transform signs - to present information into numerical forms - to a format suitable for machine learning models. Each chapter considers only one data processing task, for example, how to represent text data or images. And together they present the main principles of designing signs.
