A Gaussian process framework learns particle interaction models and governing equations from data
It identifies interaction types and system order with only scarce, noisy trajectory data
Efficient techniques are developed to improve computational scalability
The method is demonstrated on modeling real fish schooling data
Learning particle interaction rules from motion data
This paper develops a Gaussian process-based approach to learn interaction models for particle systems from scarce, noisy trajectory data. It can identify if interactions depend on positions, velocities, or both, and if the system is first or second order. The method is applied to model real fish schooling data.
