reducing action space!

Hi Amir,

Thanks for sharing the code. very interesting stuff. I was wondering if it is possible to modify the lumbar spine model. Specifically, I am looking to reducee the number of muscles in the action space. How can I go about doing that?

Thanks,

Hi, Yes that is possible. You can make any modifications in the Artisynth model by updating the source code in java.

Thanks, I figured that out. I do have another question though. Once a policy is trained, can it be generalized to the motion of a scaled model (i.e. different mass or size)?

Well, if it has never seen any variability in the mass and size factors of the state space, I won't expect it to adopt to such change. So: no.
