Overview of this book

Deep learning is a branch of machine learning based on a set of algorithms that attempt to model high-level abstractions in data. Advanced Deep Learning with R will help you understand popular deep learning architectures and their variants in R, along with providing real-life examples for them. This deep learning book starts by covering the essential deep learning techniques and concepts for prediction and classification. You will learn about neural networks, deep learning architectures, and the fundamentals for implementing deep learning with R. The book will also take you through using important deep learning libraries such as Keras-R and TensorFlow-R to implement deep learning algorithms within applications. You will get up to speed with artificial neural networks, recurrent neural networks, convolutional neural networks, long short-term memory networks, and more using advanced examples. Later, you'll discover how to apply generative adversarial networks (GANs) to generate new images; autoencoder neural networks for image dimension reduction, image de-noising and image correction and transfer learning to prepare, define, train, and model a deep neural network. By the end of this book, you will be ready to implement your knowledge and newly acquired skills for applying deep learning algorithms in R through real-world examples.

Performance optimization tips and best practices

When developing a recurrent neural network model, we come across situations where we need to make several decisions related to the network. These decisions could include trying a different activation function rather than the default one that we had used. Let's make such changes and see what impact they have on the movie review sentiment classification performance of the model.

In this section, we will experiment with the following four factors:

  • Number of units in the simple RNN layer
  • Using different activation functions in the simple RNN layer
  • Adding more recurrent layers
  • Changes in the maximum length for padding sequences
