Book Description

Feature engineering is the most important step in creating powerful machine learning systems. This book will take you through the entire feature engineering journey to make machine learning much more systematic and effective.

You will start with understanding your data; often the success of your ML models depends on how you leverage different feature types, such as continuous, categorical, and more. You will learn when to include a feature, when to omit it, and why, all by understanding error analysis and the acceptability of your models. You will also learn to convert a problem statement into useful new features. This book will guide you in delivering features driven by business needs as well as mathematical insights, and you'll see how to use machine learning for your data.

By the end of the book, you will have become proficient in feature selection, feature learning, and feature pptimization.

What you will learn

• Identify and leverage different feature types
• Clean features in data to improve predictive power
• Understand why and how to perform feature selection and model error analysis
• Leverage domain knowledge to construct new features
• Deliver features based on mathematical insights
• Use machine learning algorithms to construct features
