MSIT 423: Data Mining and Business Intelligence

Quarter Offered

Spring : Saturday, 2:00pm-5:00pm ; Edward Malthouse, Ph.D

Description

In the rapidly changing business environment, with global competition and maturing markets, competitive advantage is extremely important. Business can exploit the wealth of massive amounts of data being collected through operational processes as well as from external sources. This course introduces techniques for data mining and its use in various business applications to enable business intelligence. The course uses both hands-on experience using state-of-the-art data mining tools to model business problems and discover interesting patterns for decision support as well as several cases that discuss strategies, outcomes and impact on organizations when using data mining.

REQUIRED TEXT: James, Witten, Hastie and Tibshirani, An Introduction to Statistical Learning, Springer, 2013.

REFERENCE TEXT: 

COURSE GOALS: Students will understand and manage the entire process of using data to make better business decisions: extraction, cleaning, understanding, modeling, and presenting. Students will also understand the limitations of data.
