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.

Sentiment analysis using Word2Vec and LSTM

First, let's define the problem. Given a movie review (raw text), we have to classify that movie review as either positive or negative based on the words it contains, that is, sentiment. We do this by combining the Word2Vec model and LSTM: each word in a review is vectorized using the Word2Vec model and fed into an LSTM net. As stated earlier, we will train data in the Large Movie Review dataset. Now, here is the workflow of the overall project:

First, we download the movie/product reviews dataset
Then we create or reuse an existing Word2Vec model (for example, Google News word vectors)
Then we load each review text and convert words to vectors and reviews to sequences of vectors
Then we create and train the LSTM network
Then we save the trained model
Then we evaluate the model on the test set
Then we restore the trained model and...
