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.

Use case – collaborative filtering


This use-case is about collaborative filtering. We are going to build a recommendation system based on embeddings created from a deep learning model. To do this, we are going to use the same dataset we used in Chapter 4, Training Deep Prediction Models, which is the retail transactional database. If you have not already downloaded the database, then go to the following link, https://www.dunnhumby.com/sourcefiles, and select Let’s Get Sort-of-Real. Select the option for the smallest dataset, titled All transactions for a randomly selected sample of 5,000 customers. Once you have read the terms and conditions and downloaded the dataset to your computer, unzip it into a directory called dunnhumby/in under the code folder. Ensure that the files are unzipped directly under this folder, and not a subdirectory, as you may have to copy them after unzipping the data.

The data contains details of retail transactions linked by basket IDs. Each transaction has a date...
