Uncovering the Lagrangian from Observations of Trajectories

Uncovering the Lagrangian from Observations of Trajectories

We approach the problem of automatically modeling a mechanical system from data about its dynamics, using a method motivated by variational integrators. We write the discrete Lagrangian as a quadratic polynomial with varying coefficients, and then use the discrete Euler-Lagrange equations to numeric...
