Deep Learning with R for Beginners

By: Mark Hodnett, Joshua F. Wiley, Yuxi (Hayden) Liu, Pablo Maldonado

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.

TensorFlow estimators and TensorFlow runs packages


TensorFlow estimators and the TensorFlow runs packages are great packages to use for deep learning. In this section, we will use both to train a model based on our churn prediction data from Chapter 4, Training Deep Prediction Models.

TensorFlow estimators

TensorFlow estimators allow you to build TensorFlow models using a simpler API interface. In R, the tfestimators package allows you to call this API. There are different model types, including linear models and neural networks. The following estimators are available:

  • linear_regressor() for linear regression
  • linear_classifier() for linear classification
  • dnn_regressor() for deep neural network regression
  • dnn_classifier() for deep neural network classification
  • dnn_linear_combined_regressor() for deep neural network linear combined regression
  • dnn_linear_combined_classifier() for deep neural network linear combined classification

Estimators hide a lot of the detail in creating a deep learning model...
