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.

Introduction to the COMPAS dataset case study

In the realm of machine learning, where data drives decision-making, the line between algorithmic precision and ethical fairness often blurs. The COMPAS dataset, a collection of criminal offenders screened in Broward County, Florida, during 2013-2014, serves as a poignant reminder of this intricate dance. While, on the surface, it might appear as a straightforward binary classification task, the implications ripple far beyond simple predictions. Each row and feature isn’t just a digit or a class; it represents years, if not decades, of human experiences, ambitions, and lives. As we dive into this case study, we are reminded that these aren’t mere rows and columns but people with aspirations, dreams, and challenges. With a primary focus on predicting recidivism (the likelihood of an offender to re-offend), we’re confronted with not just the challenge of achieving model accuracy but also the monumental responsibility...
