Abstract
Among the data mining tasks, the extraction of patterns that show relevant spatial and temporal dependencies among data is one of the most useful in order to deal with a wide range of fields of application. In this thesis, we leveraged on an existing data mining algorithm specifically designed to handle spatio-temporal events to extract association rules. Such rules are applied in a predictive context to a real-case scenario, a station-based bike sharing system. More specifically, we take into account the analysis of years of historical data about a bike-sharing service based in San Francisco, from which we want to extract patterns useful to deploy an associative classifier.
The objective is to look for patterns which embody both the spatial and temporal dimensions, in a way that is not specific of certain trajectories observed over a region of interest: we aim to generalize this type of information by detecting sequences of events of interest, reporting spatiotemporally invariant properties
