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 is a challenging task

Text analytics in NLP is all about processing and analyzing large-scale structured and unstructured text to discover hidden patterns and themes and derive contextual meaning and relationships. Text analytics has so many potential use cases, such as sentiment analysis, topic modeling, TF-IDF, named entity recognition, and event extraction.

Sentiment analysis includes many example use cases, such as analyzing the political opinions of people on Facebook, Twitter, and other social media. Similarly, analyzing the reviews of restaurants on Yelp is also another great example of Sentiment Analysis. NLP frameworks and libraries such as OpenNLP and Stanford NLP are typically used to implement sentiment analysis.

However, for analyzing sentiments using text, particularly unstructured texts, we must find a robust and efficient way of feature engineering...
