Overview of this book

Meta learning is an exciting research trend in machine learning, which enables a model to understand the learning process. Unlike other ML paradigms, with meta learning you can learn from small datasets faster. Hands-On Meta Learning with Python starts by explaining the fundamentals of meta learning and helps you understand the concept of learning to learn. You will delve into various one-shot learning algorithms, like siamese, prototypical, relation and memory-augmented networks by implementing them in TensorFlow and Keras. As you make your way through the book, you will dive into state-of-the-art meta learning algorithms such as MAML, Reptile, and CAML. You will then explore how to learn quickly with Meta-SGD and discover how you can perform unsupervised learning using meta learning with CACTUs. In the concluding chapters, you will work through recent trends in meta learning such as adversarial meta learning, task agnostic meta learning, and meta imitation learning. By the end of this book, you will be familiar with state-of-the-art meta learning algorithms and able to enable human-like cognition for your machine learning models.

Meta imitation learning


If we want our robot to be more generalist and to perform various tasks, then our robots should learn quickly. But how can we enable our robots to learn quickly? Well, how do we humans learn quickly? Don't we easily learn new skills by just looking at other individuals? Similarly, if we enable our robot to learn by just looking at our actions, then we can easily make the robot learn complex goals efficiently and we don't have to engineer complex goal and reward functions. This type of learning—that is, learning from human actions—is called imitation learning, where the robot tries to mimic human action. A robot doesn't really have to learn only from human actions; it can also learn from another robot performing a task or a video of a human/robot performing a task.

But imitation learning is not as simple as it sounds. A robot will take a lot of time and demonstrations to learn the goal and to identify the right policy. So, we'll augment the robot with prior experience...
