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 of pre-trained models gave us insight into how these models, trained on extensive data and time, provide a solid foundation for us to build upon. They help us overcome constraints related to computational resources and data availability. Notably, we familiarized ourselves with image-based models such as VGG16 and ResNet, and text-based models such as BERT and GPT, adding them to our repertoire.

Our voyage continued into the domain of TL, where we learned its fundamentals, recognized its versatile applications, and acknowledged its different forms—inductive, transductive, and unsupervised. Each type, with its unique characteristics, adds a different dimension to our ML toolbox. Through practical examples, we saw these concepts in action, applying a BERT model for text classification and a Vision Transformer for image classification.

But, as we’ve come to appreciate, TL and pre-trained models, while powerful, are not the solution to all data...
