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.

Mitigating Algorithmic Bias and Tackling Model and Data Drift

If you’re playing in the arena of machine learning (ML) and data science, you’re going to run into some hurdles. You can count on meeting two challenges: algorithmic bias and model and data drift. They’re like the tricky questions in a pop quiz – you might not see them coming, but you’d better be prepared to handle them.

Algorithmic bias can creep into our models, and when it does, it’s not a good look. It can lead to unfair results, and, quite frankly, it’s just not cool. But don’t worry – we’re going to tackle it head on and talk about ways to mitigate it.

Even if we consider bias, over time, changes can happen that make our models less accurate. It’s like when your favorite shirt shrinks in the wash – it’s not the shirt’s fault, but it doesn’t fit like it used to. The same happens with our models. They may have...
