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.

Types of ML

There are many ways to segment ML and dive deeper. In Chapter 1, Data Science Terminology, I mentioned statistical and probabilistic models. These models utilize statistics and probability, which we’ve seen in the previous chapters, in order to find relationships between data and make predictions. In this chapter, we will implement both types of models. In the following chapter, we will see ML outside the rigid mathematical world of statistics/probability. You can segment ML models by different characteristics, including the following:

  • The types of data organic structures they utilize (tree, graph, or neural network (NN))
  • The field of mathematics they are most related to (statistical or probabilistic)
  • The level of computation required to train (deep learning (DL))

Branching off from the top level of ML, there are the following three subsets:

  • Supervised learning (SL)
  • Unsupervised learning (UL)
  • Reinforcement learning (RL)
  • ...
