Overview of this book

You already know you want to learn data science, and a smarter way to learn data science is to learn by doing. The Data Science Workshop focuses on building up your practical skills so that you can understand how to develop simple machine learning models in Python or even build an advanced model for detecting potential bank frauds with effective modern data science. You'll learn from real examples that lead to real results. Throughout The Data Science Workshop, you'll take an engaging step-by-step approach to understanding data science. You won't have to sit through any unnecessary theory. If you're short on time you can jump into a single exercise each day or spend an entire weekend training a model using sci-kit learn. It's your choice. Learning on your terms, you'll build up and reinforce key skills in a way that feels rewarding. Every physical print copy of The Data Science Workshop unlocks access to the interactive edition. With videos detailing all exercises and activities, you'll always have a guided solution. You can also benchmark yourself against assessments, track progress, and receive content updates. You'll even earn a secure credential that you can share and verify online upon completion. It's a premium learning experience that's included with your printed copy. To redeem, follow the instructions located at the start of your data science book. Fast-paced and direct, The Data Science Workshop is the ideal companion for data science beginners. You'll learn about machine learning algorithms like a data scientist, learning along the way. This process means that you'll find that your new skills stick, embedded as best practice. A solid foundation for the years ahead.

Introduction

In the previous chapters, we learned how to analyze and prepare a dataset in order to increase its level of quality. In this chapter, we will introduce you to another interesting topic: creating new features, also known as feature engineering. You already saw some of these concepts in Chapter 3, Binary Classification, but we will dive a bit deeper into this chapter.

The objective of feature engineering is to provide more information for the analysis you are performing on or the machine learning algorithms you will train on. Adding more information will help you to achieve better and more accurate results.

New features can come from internal data sources such as another table from databases or from different systems. For instance, you may want to link data from the CRM tool used in your company to the data from a marketing tool. The added features can also come from external sources such as open-source data or shared data from partners or providers. For example,...
