商品描述

Dive into hyperparameter tuning of machine learning models and focus on what hyperparameters are and how they work. This book discusses different techniques of hyperparameters tuning, from the basics to advanced methods.

This is a step-by-step guide to hyperparameter optimization, starting with what hyperparameters are and how they affect different aspects of machine learning models. It then goes through some basic (brute force) algorithms of hyperparameter optimization. Further, the author addresses the problem of time and memory constraints, using distributed optimization methods. Next you'll discuss Bayesian optimization for hyperparameter search, which learns from its previous history.

The book discusses different frameworks, such as Hyperopt and Optuna, which implements sequential model-based global optimization (SMBO) algorithms. During these discussions, you'll focus on different aspects such as creation of search spaces and distributed optimization of these libraries.

Hyperparameter Optimization in Machine Learning creates an understanding of how these algorithms work and how you can use them in real-life data science problems. The final chapter summaries the role of hyperparameter optimization in automated machine learning and ends with a tutorial to create your own AutoML script.

Hyperparameter optimization is tedious task, so sit back and let these algorithms do your work.

商品描述(中文翻譯)

深入探討機器學習模型的超參數調整，並專注於什麼是超參數以及它們如何運作。本書討論了從基礎到進階的不同超參數調整技術。

這是一本逐步指導超參數優化的指南，首先介紹什麼是超參數以及它們如何影響機器學習模型的不同方面。接著，將介紹一些基本的（暴力）超參數優化算法。此外，作者還針對時間和記憶體限制的問題，使用分散式優化方法。接下來，您將討論用於超參數搜尋的貝葉斯優化，該方法能從之前的歷史中學習。

本書討論了不同的框架，例如 Hyperopt 和 Optuna，這些框架實現了基於模型的全局優化（SMBO）算法。在這些討論中，您將專注於不同的方面，例如搜尋空間的創建和這些庫的分散式優化。

《機器學習中的超參數優化》幫助讀者理解這些算法的運作方式以及如何在現實數據科學問題中使用它們。最後一章總結了超參數優化在自動化機器學習中的角色，並以創建您自己的 AutoML 腳本的教程作結。

超參數優化是一項繁瑣的任務，因此請放鬆心情，讓這些算法為您工作。
