ICOM6044 Data science for business (6 credits)

The emerging discipline of data science combines statistical methods with computer science to solve problems in applied areas.  In this case we focus on how data science can be used to solve business problems especially those in electronic commerce.  By its very nature e-commerce is able to generate large amounts of data and data mining methods are quite helpful for managers in turning this data into knowledge which in turn can be used to make better decisions.  These data sets and their accompanying quantitative methods have the potential to dramatically change decision making in many areas of business.  For example, ideas like interactive marketing, customer relationship management, and database marketing are pushing companies to utilize the information they collect about their customers in order to make better marketing decisions.
 

This course focuses on how data science methods can be applied to solve managerial problems in marketing and electronic commerce.  Our emphasis is developing a core set of principles that embody data science: empirical reasoning, exploratory and visual analysis, and predictive modeling.  We use these core principles to understand many methods used in data mining and machine learning.  Our strategy in this course is to survey several popular techniques and understand how they map into these core principles.  These techniques are illustrated with case studies.  However, the emphasis is not on the software for implementing these techniques but on understanding the inputs and outputs of these techniques and how they are used to solve business problems.
