Overview of this book

Deep learning (DL) has evolved in recent years with developments such as generative adversarial networks (GANs), variational autoencoders (VAEs), and deep reinforcement learning. This book will get you up and running with R 3.5.x to help you implement DL techniques. The book starts with the various DL techniques that you can implement in your apps. A unique set of recipes will help you solve binomial and multinomial classification problems, and perform regression and hyperparameter optimization. To help you gain hands-on experience of concepts, the book features recipes for implementing convolutional neural networks (CNNs), recurrent neural networks (RNNs), and Long short-term memory (LSTMs) networks, as well as sequence-to-sequence models and reinforcement learning. You’ll then learn about high-performance computation using GPUs, along with learning about parallel computation capabilities in R. Later, you’ll explore libraries, such as MXNet, that are designed for GPU computing and state-of-the-art DL. Finally, you’ll discover how to solve different problems in NLP, object detection, and action identification, before understanding how to use pre-trained models in DL apps. By the end of this book, you’ll have comprehensive knowledge of DL and DL packages, and be able to develop effective solutions for different DL problems.

Recurrent Neural Networks in Action

Sequence data is data where the order matters, such as in audio, video, and speech. Learning sequential data is one of the most challenging problems in the field of pattern recognition because of the nature of the data. The dependencies between the parts of sequences and their varying length add further complexity when processing sequential data. With the advent of sequence models and algorithms such as recurrent neural networks (RNN), long short-term memory models (LSTM), and gated recurrent units (GRU), sequence data modeling is being utilized in multiple applications, such as sequence classification, sequence generation, speech to text conversion, and many more.

In sequence classification, the goal is to predict the category of the sequence, whereas in sequence generation, we generate a new output sequence based on...
