Java Deep Learning Projects

Overview of this book

Java is one of the most widely used programming languages. With the rise of deep learning, it has become a popular choice of tool among data scientists and machine learning experts. Java Deep Learning Projects starts with an overview of deep learning concepts and then delves into advanced projects. You will see how to build several projects using different deep neural network architectures such as multilayer perceptrons, Deep Belief Networks, CNN, LSTM, and Factorization Machines. You will get acquainted with popular deep and machine learning libraries for Java such as Deeplearning4j, Spark ML, and RankSys and you’ll be able to use their features to build and deploy projects on distributed computing environments. You will then explore advanced domains such as transfer learning and deep reinforcement learning using the Java ecosystem, covering various real-world domains such as healthcare, NLP, image classification, and multimedia analytics with an easy-to-follow approach. Expert reviews and tips will follow every project to give you insights and hacks. By the end of this book, you will have stepped up your expertise when it comes to deep learning in Java, taking it beyond theory and be able to build your own advanced deep learning systems.

Summary

In this chapter, we saw how to develop a movie recommendation system using FMs, which are a set of algorithms that enhance the performance of linear models by incorporating second-order feature interactions that are absent in matrix factorization algorithms in a supervised way.

Nevertheless, we have seen some theoretical background of recommendation systems using matrix factorization and collaborative filtering before diving into the project's implementation using RankSys library-based FMs. Due to page limitation, I didn't discuss the library more extensively. However, readers are suggested to take a look athe API documentation on GitHub at https://github.com/RankSys/RankSys.

This project not only covers movie rating prediction by individual users but also discusses ranking prediction, too. Consequently, we also used FMs for predicting the ranking of movies.
