| Summary |
From the coursebook. Thanks to data analytics, enormous and increasing amounts of data are transforming our world. Within the bits and bytes lies great potential to understand our past and predict future events. And this potential is being realized. Organizations of all kinds are devoting their energies to combing the ever-growing stores of high-quality data. This course demonstrates how Google, the United States Postal Service, and Visa, among many others, are using new kinds of data, and new tools, to improve their operations. Google analyzes connections between web pages, a new idea that propelled them ahead of their search engine competitors. The US Postal Service uses regression to read handwritten zip codes from envelopes, saving millions of dollars in costs. Visa employs techniques in anomaly detection to identify fraud -- and today can look at all credit card data rather than a sampling -- and with such advances comes more accurate methods. This course will help you understand the range of important tools in data analytics, as well as how to learn from data sets that interest you. The different tools of data analysis serve different purposes. We discuss important issues that guide all analysis. We see how dangerously prone humans are to finding patterns. We see how the efficiency of algorithms can differ dramatically, making some impractical for large data sets. We also discuss the emerging and important field that surrounds how to store such large data sets (p. 1). |
