Deep Learning with R for Beginners

Overview of this book

Deep learning has a range of practical applications in several domains, while R is the preferred language for designing and deploying deep learning models. This Learning Path introduces you to the basics of deep learning and even teaches you to build a neural network model from scratch. As you make your way through the chapters, you’ll explore deep learning libraries and understand how to create deep learning models for a variety of challenges, right from anomaly detection to recommendation systems. The Learning Path will then help you cover advanced topics, such as generative adversarial networks (GANs), transfer learning, and large-scale deep learning in the cloud, in addition to model optimization, overfitting, and data augmentation. Through real-world projects, you’ll also get up to speed with training convolutional neural networks (CNNs), recurrent neural networks (RNNs), and long short-term memory networks (LSTMs) in R. By the end of this Learning Path, you’ll be well-versed with deep learning and have the skills you need to implement a number of deep learning concepts in your research work or projects.

Summary


We just accomplished our second computer vision project in this R and deep learning journey! Through this chapter, we got more familiar with convolutional neural networks and their implementation in MXNet, and another powerful deep learning tool: Keras with TensorFlow.

We started with what self-driving cars are and how deep learning techniques are making self-driving cars feasible and more reliable. We also discussed how deep learning stands out and becomes the state-of-the-art solution for object recognition in intelligent vehicles. After exploring the traffic sign dataset, we developed our first CNN model using MXNet and achieved more than 99% accuracy. Then we moved on to another powerful deep learning framework, Keras + TensorFlow, and obtained comparable results.

We introduced the dropout technique to reduce overfitting. We also learned how to deal with lack of training data and utilize data augmentation techniques, including flipping, shifting, and rotation. We finally wrapped...
