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.

Developing a GridWorld game using a deep Q-network

We will now start diving into Deep Q-Network (DQN) to train an agent to play GridWorld, which is a simple text-based game. There is a 4 x 4 grid of tiles and four objects are placed. There is an agent (a player), a pit, a goal, and a wall.

GridWorld project structure

The project has the following structure:

  • DeepQNetwork.java: Provides the reference architecture for the DQN
  • Replay.java: Generates replay memory for the DQN to ensure that the gradients of the deep network are stable and do not diverge across episodes
  • GridWorld.java: The main class used for training the DQN and playing the game.

By the way, we perform the training on GPU and cuDNN for faster convergence. However, feel free to use the CPU backend as well if your machine does not have a GPU.
