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.

Answers to questions

Answer to question 1: Do not confuse the Q in Q-learning with the Q-function we have discussed in the previous parts. The Q-function is always the name of the function that accepts states and actions and spits out the value of that state-action pair. RL methods involve a Q-function but are not necessarily Q-learning algorithms.

Answer to question 2: No worries as you can perform the training on a CPU backend too. In that case, just remove the entries for CUDA and cuDNN dependencies from the pom.xml file and replace them with the CPU ones. The properties would be:

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
<nd4j.version>1.0.0-alpha</nd4j.version>
<dl4j.version>1.0.0-alpha</dl4j.version>
<datavec.version...
