Overview of this book

Deep learning is driving the AI revolution, and PyTorch is making it easier than ever before for anyone to build deep learning applications. This PyTorch book will help you uncover expert techniques to get the most out of your data and build complex neural network models. The book starts with a quick overview of PyTorch and explores using convolutional neural network (CNN) architectures for image classification. You'll then work with recurrent neural network (RNN) architectures and transformers for sentiment analysis. As you advance, you'll apply deep learning across different domains, such as music, text, and image generation using generative models and explore the world of generative adversarial networks (GANs). You'll not only build and train your own deep reinforcement learning models in PyTorch but also deploy PyTorch models to production using expert tips and techniques. Finally, you'll get to grips with training large models efficiently in a distributed manner, searching neural architectures effectively with AutoML, and rapidly prototyping models using PyTorch and fast.ai. By the end of this PyTorch book, you'll be able to perform complex deep learning tasks using PyTorch to build smart artificial intelligence models.

Generating MIDI music with LSTMs using PyTorch

Moving on from text, in this section, we will use PyTorch to create a machine learning model that can compose classical-like music. We used transformers for generating text in the previous section. Here, we will use an LSTM model to process sequential music data. We will train the model on Mozart's classical music compositions.

Each musical piece will essentially be broken down into a sequence of piano notes. We will be reading music data in the form of Musical Instruments Digital Interface (MIDI) files, which is a well-known and commonly used format for conveniently reading and writing musical data across devices and environments.

After converting the MIDI files into sequences of piano notes (which we call the piano roll), we will use them to train a next-piano-note detection system. In this system, we will build an LSTM-based classifier that will predict the next piano note for the given preceding sequence of piano notes,...
