PyTorch Deep Learning Hands-On

By: Sherin Thomas, Sudhanshu Passi

Overview of this book

PyTorch Deep Learning Hands-On is a book for engineers who want a fast-paced guide to doing deep learning work with PyTorch. It is not an academic textbook and does not try to teach deep learning principles. The book will help you most if you want to get your hands dirty and put PyTorch to work quickly. PyTorch Deep Learning Hands-On shows how to implement the major deep learning architectures in PyTorch. It covers neural networks, computer vision, CNNs, natural language processing (RNN), GANs, and reinforcement learning. You will also build deep learning workflows with the PyTorch framework, migrate models built in Python to highly efficient TorchScript, and deploy to production using the most sophisticated available tools. Each chapter focuses on a different area of deep learning. Chapters start with a refresher on how the model works, before sharing the code you need to implement it in PyTorch. This book is ideal if you want to rapidly add PyTorch to your deep learning toolset.

Design and experimentation

After the theoretical foundation of the problem statement is built, we move to the design and/or experimentation phase where we build the POC by trying out several model implementations. The crucial part of design and experimentation lies in the dataset and the preprocessing of the dataset. For any data science project, the major time share is spent on data cleaning and preprocessing. Deep learning is no different from this.

Data preprocessing is one of the vital parts of building a deep learning pipeline. Real-world datasets are not cleaned or formatted, usually, for a neural network to process. Conversion to floats or integers, normalization and so on, is required before further processing. Building a data processing pipeline is also a non-trivial task, which consists of writing a lot of boilerplate code. To make it much easier, dataset builders and DataLoader pipeline packages are built into the core of PyTorch.
