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 stock price predictive model

As stated earlier, the stock market price has severe volatility and historical perspective, which make it suited for time analysis. This also challenges those classical algorithms, since long-term dependencies cannot be availed using those algorithms.

As outlined in following diagram, first we collect historical financial data. The data is then converted into a time series after the necessary preprocessing and feature engineering. The resultant time series data is then fed into the LSTM to carry out the training. The following diagram illustrates this:

Therefore, we will be using LSTM not only because it outperforms classical algorithms but also because we can solve long-term dependencies with it. Consequently, our project will have the following steps:

  1. Load and preprocess...
