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: This means the training is not being distributed, which also means that your system is forcing you to use just one GPU. Now to solve this issue, just add the following line at the beginning of your main() method:

CudaEnvironment.getInstance().getConfiguration().allowMultiGPU(true);

Answer to question 2: Well, this is certainly an AWS EC2-related question. However, I will provide a short explanation. If you see the default boot device, it allocates only 7.7 GB of space, but about 85% is allocated for the udev device, as shown here:

Showing storage on a p2.8xlarge instance

Now, to get rid of this issue, you can specify sufficient storage in the boot device while creating the instance, as follows:

Increasing storage on the default boot device the on p2.8xlarge instance

Answer to question 3: Well, if this is the case, you can probably do...
