Learning Crowd Behavior

Panayiotis Charalambous, Yiorgos Chrysanthou

Presented at: Workshop on Crowd Simulation (co-located with CASA2010), Jun 2010

We present here our ongoing work on learning crowd behavior. The steering behavior of crowds from various video sources is tracked and databases of examples are generated. These examples contain various stimuli (metrics) that could affect the persons behavior. These databases are used to learn rules for crowd steering in an agent based framework using regression algorithms and more specifically, decision trees. Various simulations are run and the statistics measured at the simulation stage are compared to those of the original video to determine which stimuli affect an agents behavior the most.
