In this paper we consider the problem of detecting commuting patterns in a trajectory. For
this we search for similar subtrajectories. To measure spatial similarity we choose the …

Background Longitudinal data are data in which each variable is measured repeatedly over
time. One possibility for the analysis of such data is to cluster them. The majority of clustering …
