Analyzing User Interactions for Data and User Modeling

Monday, June 16, 2014
Dr. Remco Chang
User interactions with a visualization system reflect a great deal of the user's reasoning process and personality. In this talk, Remco will present techniques that he developed to analyze the user's interactions in order to (a) model the data in the form of metric learning that reflect a user's understanding of high-dimensional data, and (b) model the user and learn the user's individual differences and analysis behavior. In addition, he will discuss the relevant cognitive traits and states that influence a user's analysis process and conclude by suggesting how this research form the basis of mixed-initiative visual analysis systems.
