Discovery of Spatio-Temporal Patterns from Location
... Different geographical discretizations can be proposed to allow the extraction of patterns at different resolutions. A possibility is to divide the area using a regular grid. This would also allow to study the events at different levels of granularity. Controlling the size and shape of the cells it ...
