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.

Object localization

Object localization is a widespread application of deep learning and has gained a lot of traction in the field of autonomous vehicles, facial detection, object tracking, and many more. Localizing an object is the identification of an area of interest in an image and encapsulating it with a bounding box. In Chapter 1, Understanding Neural Networks and Deep Neural Networks, and Chapter 2, Working with Convolutional Neural Networks, we worked on image classification, where the output of the network is the probability of each class. For this problem, we will use networks that are similar to the ones we used for image classification, except with a different set of target variables.

In object localization, we predict the output variables that represent the position of the object of interest in the entire input image. Using these, we draw bounding...
