Hands-On One-shot Learning with Python

By: Shruti Jadon, Ankush Garg

Overview of this book

One-shot learning has been an active field of research for scientists trying to develop a cognitive machine that mimics human learning. With this book, you'll explore key approaches to one-shot learning, such as metrics-based, model-based, and optimization-based techniques, all with the help of practical examples. Hands-On One-shot Learning with Python will guide you through the exploration and design of deep learning models that can obtain information about an object from one or just a few training samples. The book begins with an overview of deep learning and one-shot learning and then introduces you to the different methods you can use to achieve it, such as deep learning architectures and probabilistic models. Once you've got to grips with the core principles, you'll explore real-world examples and implementations of one-shot learning using PyTorch 1.x on datasets such as Omniglot and MiniImageNet. Finally, you'll explore generative modeling-based methods and discover the key considerations for building systems that exhibit human-level intelligence. By the end of this book, you'll be well-versed with the different one- and few-shot learning methods and be able to use them to build your own deep learning models.

Section 3: Other Methods and Conclusion

Deep learning architectures have proven to be highly effective, but they are still not the best approach for one-shot learning. Different Bayesian approaches, such as the Bayesian programming language, can still beat humans at one-shot learning. In this section, we will learn about Bayesian methods and discuss the recent advancements that have been made in this domain. Additionally, we will compare the Bayesian method to a well-known technique—transfer learning—that exists in the deep learning circle to solve any problem. We will also learn when to use the one-shot approach over transfer learning.

This section comprises the following chapters:

  • Chapter 5, Generative Modeling-Based Methods
  • Chapter 6, Conclusions and Other Approaches
