Book Overview

Data Science for Business is a new book by Foster Provost and Tom Fawcett intended for those who need to understand data science/data mining, and those who want to develop their skill at data-analytic thinking. Data Science for Business is not a book about algorithms. Instead it presents a set of fundamental principles for extracting useful knowledge from data. These fundamental principles are the foundation for many algorithms and techniques for data mining, but also underlie the processes and methods for approaching business problems data-analytically, evaluating particular data science solutions, and evaluating general data science plans.

Design

The book builds up the reader's understanding of data science by discussing the fundamental principles in the context of business examples, and then shows specifically how the principles can provide understanding of many of the most common methods and techniques used in data science. After reading the book, the reader should be able to (i) discuss data science intelligently with data scientists and with other stakeholders, (ii) better understand proposals for data science projects and data science investments, and (iii) participate integrally in data science projects.

As one example, a fundamental principle of data science is that solutions for extracting useful knowledge from data must carefully consider the problem from the business perspective. This may sound obvious at first, but the notion underlies many choices that must be made in the process of data analytics, including problem formulation, method choice, solution evaluation, and general strategy formulation. Another fundamental principle is that some data items can give us information about other data items. This principle manifests itself throughout data science: in the basic notion of finding “correlations” among variables, in the specific design of many particular data mining procedures, and more generally as the basis for all predictive analytics.

Audience

Data Science for Business is intended for business people who will be managing or working with data scientists, for developers who will be implementing data science solutions, as well as for aspiring data scientists. By its very nature the material is somewhat technical --- the goal is to really understand data science, not to give a high-level overview. However, the book does not presume a sophisticated mathematical background, relegating the few technical details to optional "starred" sections.
