An important determinant of success today is the ability of a business to extract intelligence from data generated as a byproduct of normal operations. Typical business intelligence applications include: Recommender systems, used for example by Amazon.com to suggest additional products and by Netflix.com to suggest movies; Market-based analysis, used to identify which products are frequently purchased together. This can in turn be used for store shelf layout and for promotions to shoppers and classifier systems, used to identify customers who should receive promotional mailers or subscription offers. Also used to identify spam email. This course covers the analytic techniques currently used by businesses. Rather than stress the mechanics of the underlying mathematical and statistical concepts, the course will build a strong intuitive understanding of the techniques and leave the mechanics to statistical packages. Offered: Spring.
