深入浅出数据分析
《深入浅出数据分析》以类似“章回小说”的活泼形式,生动地向读者展现优秀的数据分析人员应知应会的技术:数据分析基本步骤、实验方法、最优化方法、假设检验方法、贝叶斯统计方法、主观概率法、启发法、直方图法、回归法、误差处理、相关数据库、数据整理技巧;正文之后,意犹未尽地以三篇附录介绍数据分析十大要务、R工具及ToolPak工具,在充分展现目标知识以外,为读者搭建了走向深入研究的桥梁。 本书构思跌宕起伏,行文妙趣横生,无论读者是职场老手,还是业界新人;无论是字斟句酌,还是信手翻阅,都能跟着文字在职场中走上几回,体味数据分析领域的乐趣与挑战。 -
Data Science from Scratch
Data science libraries, frameworks, modules, and toolkits are great for doing data science, but they’re also a good way to dive into the discipline without actually understanding data science. In this book, you’ll learn how many of the most fundamental data science tools and algorithms work by implementing them from scratch. If you have an aptitude for mathematics and some programming skills, author Joel Grus will help you get comfortable with the math and statistics at the core of data science, and with hacking skills you need to get started as a data scientist. Today’s messy glut of data holds answers to questions no one’s even thought to ask. This book provides you with the know-how to dig those answers out. Get a crash course in Python Learn the basics of linear algebra, statistics, and probability—and understand how and when they're used in data science Collect, explore, clean, munge, and manipulate data Dive into the fundamentals of machine learning Implement models such as k-nearest Neighbors, Naive Bayes, linear and logistic regression, decision trees, neural networks, and clustering Explore recommender systems, natural language processing, network analysis, MapReduce, and databases -
