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 demo GridWorld game using DL4J, RL4J, and neural Q-learning, which acts as the Q-function. We also provided some basic theoretical background necessary for developing a deep QLearning network for playing the GridWorld game. However, we did not develop any module for visualizing the moves of the agent for the entire episodes.

In the next chapter, we will develop a very common end-to-end movie recommendation system project, but with the neural Factorization Machine (FM) algorithm. The MovieLens 1 million dataset will be used for this project. We will be using RankSys and Java-based FM libraries for predicting both movie ratings and rankings from the users. Nevertheless, Spark ML will be used for exploratory analysis of the dataset.
