Abstract:

Models for large datasets are complex in qualitatively different ways than models for normal-sized datasets. Distributed computation, the use of model updating rather than recalculation, and general issues of model management become critical to success. In SPSS, we are researching techniques to manage such models. In this talk, we will outline the issues and demonstrate our approach to solving the associated problems. The focus will be on visualizing the model artifacts---the models, their accuracy, their behaviors over time, the scored results, and the model-building process.
