PAWS Meeting 2-20-2008
Mike presented the project he participated in while working with ITS group at UPMC. The project resulted in the UMUA paper.
SliceTutor is tutoring system helping medical doctors to learn making a diagnosis on the basis of a tissue samples.
The main goal of the project was to evaluate multiple cognitive models and test corresponding approaches of user modeling data aggregation. The predictive validity of resulting user models was compared using several metrics. The metrics themselves were also analyzed.
The main contributions of the project are:
- the argumentation in favor of curve-based vs point-based metrics for evaluating user models;
- recommendations for the improvement of the classical model tracing algorithm, and
- a good practice of exhaustive analysis of the diversity of user models that could be derived from a single initial data set of raw usage transactions.
