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.

Frequently asked questions (FAQs)

Although we have been able to solve this multi-label classification problem, the accuracy we experienced was below par. Therefore, in this section, we will see some frequently asked questions (FAQs) that might already be on your mind. Knowing the answers to these questions might help you to improve the accuracy of the CNNs we trained. Answers to these questions can be found in the Appendix:

  1. What are the hyperparameters that I can try tuning while implementing this project?
  2. My machine is getting OOP while running this project. What should I do?
  3. While training the networks with full images, my GPU is getting OOP. What should I do?
  4. I understand that the predictive accuracy using CNN in this project is still very low. Did our network under or overfit? Is there any way to observe how the training went?
  5. I am very interested in implementing the same...
