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.

Consequences of unaddressed bias and the importance of fairness

Ever been at the receiving end of a raw deal? Remember how that felt? Now, imagine that happening systematically, over and over again, thanks to an ML model. Not a pretty picture, right? That’s exactly what happens when bias goes unaddressed in AI systems.

Consider a recruitment algorithm that has been trained on a skewed dataset. It might consistently screen out potential candidates from minority groups, leading to unfair hiring practices. Or, imagine a credit scoring algorithm that’s a little too fond of a particular zip code, making it harder for residents of other areas to get loans. Unfair, right?

These real-world implications of bias can severely erode trust in AI/ML systems. If users feel that a system is consistently discriminating against them, they might lose faith in its decisions. And let’s be honest – no one wants to use a tool that they believe is biased against them.
