Personalization of Energy Expenditure Estimation in Free Living Using Topic Models 150 158 Journal of Biomedical and Health Informatics (JBHI)

We introduce an approach to personalize energy expenditure (EE) estimates in free living. First we use Topic Models (TM) to discover activity composites from recognized activity primitives and stay regions…
