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.

Summary

Our exploration into the world of ML has revealed a vast landscape that extends well beyond the foundational techniques of linear and logistic regression. We delved into decision trees, which provide intuitive insights into data through their hierarchical structure. Naïve Bayes classification offered us a probabilistic perspective, showing how to make predictions under the assumption of feature independence. We ventured into dimensionality reduction, encountering techniques such as feature extraction, which help overcome the COD and reduce computational complexity.

k-means clustering introduced us to the realm of UL, where we learned to find hidden patterns and groupings in data without pre-labeled outcomes. Across these methods, we’ve seen how ML can tackle a plethora of complex problems, from predicting categorical outcomes to uncovering latent structures in data.

Through practical examples, we’ve compared and contrasted SL, which relies on labeled...
