GraphScan: Detection and Analysis of Free-Form Spatio-Temporal Patterns
Content Type: Abstract
By capturing the spatio-temporal organization of the data using a graph, GraphScan avoids the challenges associated with trying to “fit” incoming data into moving windows of predefined shapes and sizes. Whereas the popular space-time permutation… read more… every geo- graphical region has a spatial neighbourhood (com- posed of all the regions adjacent to it), it also has a … and it’s “ future self” (i.e., the region at t + 1). One may think of the space-time graph as a structure composed of … to the level of “activity” (e.g., count of GI-related ED visits) for the corresponding region and time period. …
