Before revision:  Our framework yields an operational method, termed Stochastic Inertial Force Inference , which performs well on experimental trajectories of single migrating cells and in complex high-dimensional systems  including flocks with Viscek-like alignment interactions.  .
After revision:  Our framework yields an operational method, termed Stochastic Inertial Force Inference , which performs well on experimental trajectories of single migrating cells and in complex high-dimensional systems including flocks with Viscek-like alignment interactions. Our method is robust to experimental measurement errors, and includes a self-consistent estimate of the inference error .
