convert new_joints to new_joint_vecs

[UsanoCoCr]

I want to mathematically convert new_joints to new_joint_vecs, I look at the code in motion_representation.ipynb I'm not sure if new_joints_vecs to new_joints is reversible, has anyone done the same thing?

i also concern about this problem, i saw someone do it like this, but im not sure if this is correct. it seems they use process_file() to
transform new_joints[time,22,3] into new_ joints_feature(vector) [time,263] directly, but joints and new_joints is different..?
