Agile Data Science

Mining data requires a deep investment in people and time. How can you be sure you're building the right models? What tools help you connect with the customer's needs? With this hands-on book, you'll learn a flexible toolset and methodology for building effective analytics applications. Agile Data shows you how to create an environment for exploring data, using lightweight tools such as Ruby, Python, Apache Pig, and the D3.js (Data-Driven Documents) JavaScript library. You'll learn an iterative approach that allows you to quickly change the kind of analysis you're doing, as you discover what the data is telling you. All the example code in this book is available as working Heroku apps.
