Advanced Deep Learning with R

By: Bharatendra Rai

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.

Summary

In this chapter, we saw how to develop a neural network model that helps to solve a classification type of problem. We started with a simple classification model and explored how to change the number of hidden layers and the number of units in the hidden layers. The idea behind exploring and fine-tuning a classification model was to illustrate how to explore and improve the performance of the classification model. We also saw how to dig deeper to understand the performance of a classification model with the help of a confusion matrix. We purposefully looked at a relatively smaller neural network model at the beginning of this chapter and finished with an example of a relatively deeper neural network model. Deeper networks involving several hidden layers can also lead to overfitting problems, where a classification model may have excellent performance with training data...
