Hyperparameter Tuning with Python

By: Louis Owen

Overview of this book

Hyperparameters are an important element in building useful machine learning models. This book curates numerous hyperparameter tuning methods for Python, one of the most popular coding languages for machine learning. Alongside in-depth explanations of how each method works, you will use a decision map that can help you identify the best tuning method for your requirements. You’ll start with an introduction to hyperparameter tuning and understand why it's important. Next, you'll learn the best methods for hyperparameter tuning for a variety of use cases and specific algorithm types. This book will not only cover the usual grid or random search but also other powerful underdog methods. Individual chapters are also dedicated to the three main groups of hyperparameter tuning methods: exhaustive search, heuristic search, Bayesian optimization, and multi-fidelity optimization. Later, you will learn about top frameworks like Scikit, Hyperopt, Optuna, NNI, and DEAP to implement hyperparameter tuning. Finally, you will cover hyperparameters of popular algorithms and best practices that will help you efficiently tune your hyperparameter. By the end of this book, you will have the skills you need to take full control over your machine learning models and get the best models for the best results.

In this chapter, we have learned all we need to know about hyperparameter tuning, starting from what it is, what is its goal, and when we should perform hyperparameter tuning. We have also discussed the difference between hyperparameters and parameters, the concept of hyperparameter space, and the concept of hyperparameter distributions. Having a clear picture of the concept of hyperparameter tuning and hyperparameters themselves will help you a lot in the following chapters.

As stated previously, we will discuss all of the four categories of hyperparameter-tuning methods in this book. In Chapter 3, Exploring Exhaustive Search, we will start discussing the first group and the most widely used hyperparameter-tuning methods in practice. There will be both high-level and detailed explanations to help you understand each of the methods more easily.
