Andreas Weigend (Weigend Associates LLC) Title: Recent Data Mining and Modeling Problems in Finance and E-Business Abstract: In data mining, successful approaches combine three areas: useful data, appropriate algorithms, and knowledge of the domain and its questions. This talk focuses on the third area. It presents several projects both from the areas of financial services and e-business, include stock trading transactions analysis, and text information extraction. Rather than discussing details of the algorithms, this talk analyzes the features of the problems that determined successes and failures of the projects.
