Principles of Data Science - Third Edition

By: Sinan Ozdemir

Overview of this book

Principles of Data Science bridges mathematics, programming, and business analysis, empowering you to confidently pose and address complex data questions and construct effective machine learning pipelines. This book will equip you with the tools to transform abstract concepts and raw statistics into actionable insights. Starting with cleaning and preparation, you’ll explore effective data mining strategies and techniques before moving on to building a holistic picture of how every piece of the data science puzzle fits together. Throughout the book, you’ll discover statistical models with which you can control and navigate even the densest or the sparsest of datasets and learn how to create powerful visualizations that communicate the stories hidden in your data. With a focus on application, this edition covers advanced transfer learning and pre-trained models for NLP and vision tasks. You’ll get to grips with advanced techniques for mitigating algorithmic bias in data as well as models and addressing model and data drift. Finally, you’ll explore medium-level data governance, including data provenance, privacy, and deletion request handling. By the end of this data science book, you'll have learned the fundamentals of computational mathematics and statistics, all while navigating the intricacies of modern ML and large pre-trained models like GPT and BERT.

How to Tell if Your Toaster is Learning – Machine Learning Essentials

It seems as though every time we hear about the next great start-up or turn on the news, we hear something about a revolutionary piece of machine learning (ML) or artificial intelligence (AI) technology and how it will change the way we live. This chapter focuses on ML as a practical part of data science. We will cover the following topics in this chapter:

  • Defining different types of ML, along with examples of each kind
  • Regression and classification
  • What is ML, and how is it used in data science?
  • The differences between ML and statistical modeling and how ML is a broad category of the latter
  • An Introduction to Linear Regression

Our aim in this chapter will be to utilize statistics, probability, and algorithmic thinking in order to understand and apply essential ML skills to practical industries, such as marketing. Examples will include predicting star ratings of restaurant reviews...
