Book Description
Java is the most popular programming language,according to the TIOBE index,and it is a very 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,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 the solutions with the existent 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 with 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,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.

图书说明
根据TIOBE指数，Java是最受欢迎的编程语言，它是在许多公司，无论是在初创企业还是在大型企业之间运行生产系统的典型选择。
毫不奇怪，它也是创建数据科学应用程序的常用选择: 它是快速的，具有内置和外部的一整套数据处理工具。更重要的是，为数据科学选择Java可让您轻松将解决方案与现有软件集成，并以较少的努力将数据科学投入生产。
本书将教您如何使用Java创建数据科学应用程序。首先，我们将在启动Data Science应用程序时修改最重要的事情，然后在深入了解更多高级主题之前，先刷新Java和机器学习的基础知识。我们首先介绍现有的数据处理库和机器学习库算法。之后，我们讨论了分类和回归，维数降低和聚类，信息检索和自然语言处理，深度学习和大数据等主题。
最后，我们通过谈论在生产环境中部署模型并进行评估的方法来完成这本书。
