As mentioned in paper, you train the neural kinematics estimator with AMASS dataset. How to get the gt joint velocity from AMASS dataset? Just smpl_joint(t) - smpl_joint(t - 1)?

Yes. Just calculate the joint position in the global space and use finite difference to compute the velocity. Then transform the velocity to the root space. Please see appendix A in the paper.

Another question about the training dataset: how to get the gt foot-ground contact from AMASS dataset?

You can find this in the paper: a foot that has a low velocity is labeled as in contact
