| Title: |
Spatiotemporal Stream Mining using EMM
|
| Abstract: |
A common characteristic of a data stream is its high volume of data; moreover the data continuously arrives at a rapid rate. It is not feasible to store all data from a stream, and this implies a single pass restriction for the data. Therefore, the data stream must be modeled in order to obtain a synopsis of a global profile for the data. Data mining is a key technique in modeling stream data. In our research we create a synopsis of the data using a dynamic Markov chain called an Extensible Markov Model (EMM). We have successfully used EMM to model stream data obtained from various types of sensors including river flow data, VoIP traffic, and seismic data. EMM applications include prediction of future values from the stream, anomaly detection, and classification. In this talk we explore the use of EMM and its effectiveness as a spatiotemporal stream modeling tool. We explore ongoing research in the area of bioinformatics and rare event detection.
Short Bio: Margaret (Maggie) H. Dunham received the B.A. and M.S. degrees in mathematics from Miami University, Oxford, Ohio, and the Ph.D. degree in computer science from Southern Methodist University in 1970, 1972, and 1984 respectively. From August 1984 to the present, she has been first an assistant professor, an associate professor, and now a Professor in the department of Computer Science and Engineering at Southern Methodist University in Dallas. Professor Dunham's current research interests are in the areas of Data Mining and Bioinformatics. Her previous research has encompassed Database Concurrency Control, Main Memory Databases, Temporal Databases, and Mobile Computing. Dr. Dunham is author of the popular data mining text Data Mining Introductory and Advanced Topics published by Prentice-Hall. Dr. Dunham was Associate Editor of the IEEE Transaction on Knowledge and Data Engineering from 2000-2004, editor of the ACM SIGMOD Record from 1986 to 1988, as well as guest editor for several special issues of IEEE and ACM journals. She served as the general conference chair for the ACM SIGMOD/PODS conference held in Dallas in May 2000, and has served on the program and organizing committees for many ACM and IEEE conferences. She has published over 100 technical papers in many diverse database and data mining topics. Professor Dunham lives in Dallas with husband Jim, daughters Stephanie and Kristina, cats Missy and Ringo, and dog Sandy.
