Mastering Java for Data Science oleh Alexey Grigorev

Key FeaturesAn overview of modern Data Science and Machine Learning libraries available in JavaCoverage of a broad set of topics, going from the basics of Machine Learning to Deep Learning and Big Data frameworks.Easy-to-follow illustrations and the running example of building a search engine.Book DescriptionJava is the most popular programming language, according to the TIOBE index, and it is a typical choice for running production systems in many companies, both in the startup world and among large enterprises.Not surprisingly, it is also a common choice for creating data science applications: it is fast and has a great set of data processing tools, both built-in and external. What is more, choosing Java for data science allows you to easily integrate solutions with existing software, and bring data science into production with less effort.This book will teach you how to create data science applications with Java. First, we will revise the most important things when starting a data science application, and then brush up the basics of Java and machine learning before diving into more advanced topics. We start by going over the existing libraries for data processing and libraries with machine learning algorithms. After that, we cover topics such as classification and regression, dimensionality reduction and clustering, information retrieval and natural language processing, and deep learning and big data.Finally, we finish the book by talking about the ways to deploy the model and evaluate it in production settings.What you will learnGet a solid understanding of the data processing toolbox available in JavaExplore the data science ecosystem available in JavaFind out how to approach different machine learning problems with JavaProcess unstructured information such as natural language text or imagesCreate your own search engineGet state-of-the-art performance with XGBoostLearn how to build deep neural networks with DeepLearning4jBuild applications that scale and process large amounts of dataDeploy data science models to production and evaluate their performanceAbout the AuthorAlexey Grigorev is a skilled data scientist, machine learning engineer, and software developer with more than 7 years of professional experience.He started his career as a Java developer working at a number of large and small companies, but after a while he switched to data science. Right now, Alexey works as a data scientist at Searchmetrics, where, in his day-to-day job, he actively uses Java and Python for data cleaning, data analysis, and modeling.His areas of expertise are machine learning and text mining, but he also enjoys working on a broad set of problems, which is why he often participates in data science competitions on platforms such as kaggle.com.You can connect with Alexey on LinkedIn at https://de.linkedin.com/in/agrigorev.Table of ContentsData Science Using JavaData Processing ToolboxExploratory Data AnalysisSupervised Learning - Classification and RegressionUnsupervised Learning - Clustering and Dimensionality ReductionWorking with Text - Natural Language Processing and Information RetrievalExtreme Gradient BoostingDeep Learning with DeepLearning4JScaling Data ScienceDeploying Data Science Models
