+	outside of the laboratory may display marked fluctuation in the relation

+   = {This paper introduces a hierarchical Markov model that can learn and
+	infer a user's daily movements through an urban community. The model
+	uses multiple levels of abstraction in order to bridge the gap between
+	raw GPS sensor measurements and high level information such as a
+	user's destination and mode of transportation. To achieve efficient
+	inference, we apply Rao-Blackwellized particle filters at multiple
+	levels of the model hierarchy. Locations such as bus stops and parking
+	lots, where the user frequently changes mode of transportation, are
+	learned from GPS data logs without manual labeling of training data.
+	We experimentally demonstrate how to accurately detect novel behavior
+	or user errors (e.g. taking a wrong bus) by explicitly modeling activities
+	in the context of the user's historical data. Finally, we discuss
+	an application called "Opportunity Knocks" that employs our techniques
+	to help cognitively-impaired people use public transportation safely.},
