Research Focus

One of the fascinating aspects of tool building for datamining is the application of a generalized datamining tool to a specific domain. Often times, this process results in a cross disciplinary analysis of both the datamining technique and the application of the results to the domain itself. This process of cross-disciplinary analysis often leads to improvements of the tool, but more importantly, to a better understanding of the underlying domain model for the domain experts involved.

One area of cross disciplinary research that lends itself to this type of collaboration is found in medical informatics. Over the past 18 months, faculty from the University of Tennessee at Chattanooga and the University of Tennessee College of Medicine, Chattanooga Unit have begun an initiative to research the use of Bayesian Networks in forecasting outcomes related to Acute Coronary Syndrome in an emergency room setting (Fesmire and Novobilski 2003). This is viewed as a key research area as 11,000 patients with acute myocardial infarction (heart attack) and an even greater number of patients with unstable angina (chest pain) are inadvertently discharged from emergency departments nationwide. Adverse outcomes in these patients represent a significant cause of death as well as greater than 25% of malpractice awards.

Having had success with preliminary test data, we have recently begun a project to mine a 17,000 record dataset related to ACS. This project represents a chance to bring together medical informatics, high performance computing, and forecasting under uncertainty using Bayeisan Networks. We look forward to sharing our results (both medical and software) as we explore the new dataset.
