| Outline of Final Research Achievements |
Research was conducted for the purpose of modeling complex particle systems and constructing simulation. First, we analyzed the time series of the self-driven particle system and showed that the change point of complex motion can be detected by a method applying dynamic mode decomposition. Furthermore, time-series data was extracted based on the experimental images, a mathematical model for expressing this motion was estimated, and statistical analysis including causal analysis was performed. As a result, we successfully established the procedure from video to the mathematical model even for unknown motion.
