The framework is built from a probabilistic topic model learned on novel bag type representations of activity-related cues (location, proximity and their temporal variations over a day) of peoples' daily routines. Using real-life data from the Reality Mining dataset, covering 68 000+ hours of human activities, we can successfully discover location-driven (from cell tower connections) and proximity-driven (from Bluetooth information) routines in an unsupervised manner. The resulting topics meaningfully characterize some of the underlying co-occurrence structure of the activities in the dataset, including ``going to work early/late", ``being home all day", ``working constantly", ``working sporadically" and ``meeting at lunch time".}, pdf = {https://publications.idiap.ch/attachments/reports/2008/farrahi-idiap-rr-08-32.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2008/farrahi-idiap-rr-08-32.ps.gz}, ipdmembership={vision}, }
