Introduction to One-shot Learning

Humans can learn new things with a small set of examples. When presented with stimuli, humans seem to be able to understand new concepts quickly and then recognize variations of those concepts in the future. A child can learn to recognize a dog from a single picture, but a machine learning system needs a lot of examples to learn the features of a dog and recognize them in the future. Machine learning, as a field, has been highly successful at a variety of tasks, such as classification and web searching, as well as image and speech recognition. Often, however, these models do not perform well without a large amount of data (examples) to learn from. The primary motivation behind this book is to train a model with very few examples that is capable of generalizing to unfamiliar categories without extensive retraining.

Key benefits

Learn how you can speed up the deep learning process with one-shot learning

Use Python and PyTorch to build state-of-the-art one-shot learning models

Explore architectures such as Siamese networks, memory-augmented neural networks, model-agnostic meta-learning, and discriminative k-shot learning

Description

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.

Who is this book for?

If you're an AI researcher or a machine learning or deep learning expert looking to explore one-shot learning, this book is for you. It will help you get started with implementing various one-shot techniques to train models faster. Some Python programming experience is necessary to understand the concepts covered in this book.

I got this book directly from Packt website and not from amazon.I'm a recent grduate with MS in Machine Learning.This book is a great starting point to jump into few-shot learning research.It gives a brief introduction to recent Deep Neural Networks architectures. Then it takes a deep dive into recent few shot learning methodologies.The pytorch sample code makes it very easy to pickup the concepts and writte actual code.

Good book to start learning about few-shot learning. Have been through few-chapters, the concepts are explained well. It also have a code repo, which has been very helpful.

This is an excellent book to get started with the area of One-Shot learning. My favorite part of the book was the lucid explanation of concepts backed by code snippets. What's also nice is that a lot of thought has been put into the organization of the book's contents itself so a person new to the area of one and few-shot learning isn't overwhelmed. Highly recommend!

This is a pretty good introduction to One shot learning. I'm still halfway through this, but the concepts are explained clearly and there are a lot of examples. I think the authors did a good job with the do-it-yourself problems, which are quite engaging.
