In: Workshop on Machine Learning for User Modeling: Challenges, 24 - 25 Jul 2005, Edimbourg, Scotland.
We are interested in a low level part of user modeling, which
is the change detection in the context of the user. We present a method
to detect on line changes in the context of a user equipped with non
invasive sensors. Our point is to provide, in real time, series of unlabeled
contexts that can be classiffied and analyzed on a higher level.
