Synthetic Data for Machine Learning

By: Abdulrahman Kerim

Overview of this book

The machine learning (ML) revolution has made our world unimaginable without its products and services. However, training ML models requires vast datasets, which entails a process plagued by high costs, errors, and privacy concerns associated with collecting and annotating real data. Synthetic data emerges as a promising solution to all these challenges. This book is designed to bridge theory and practice of using synthetic data, offering invaluable support for your ML journey. Synthetic Data for Machine Learning empowers you to tackle real data issues, enhance your ML models' performance, and gain a deep understanding of synthetic data generation. You’ll explore the strengths and weaknesses of various approaches, gaining practical knowledge with hands-on examples of modern methods, including Generative Adversarial Networks (GANs) and diffusion models. Additionally, you’ll uncover the secrets and best practices to harness the full potential of synthetic data. By the end of this book, you’ll have mastered synthetic data and positioned yourself as a market leader, ready for more advanced, cost-effective, and higher-quality data sources, setting you ahead of your peers in the next generation of ML.

An introduction to diffusion models

In this section, we will explore diffusion models. We will compare them to Variational Autoencoders (VAEs) and Generative Adversarial Networks (GANs), which we covered in Chapter 7. This will help you to gain a holistic and comprehensive understanding of generative models. Additionally, it will make comparing and contrasting the architectures, training procedures, and data flow of these methods straightforward. Furthermore, we will also learn how to train a typical diffusion model.

Diffusion Models (DMs) are generative models that were recently proposed as a clever solution to generate images, audio, videos, time series, and texts. DMs are excellent at modeling complex probability distributions, structures, temporal dependencies, and correlations in data. The initial mathematical model behind DMs was first proposed and applied in the field of statistical mechanics to study the random motion of particles in gases and liquids. As we will see later...
