Modeling multiple types of motion
We can easily learn to model walking and
running in a single model.
This means we can share a lot of knowledge.
It should also make it much easier to learn
nice transitions between walking and running.
In a switching mixture of dynamical systems its
hard to get the latent variables to join up nicely
when we switch from one system to another.
Because we can do online inference (slightly
incorrectly), we can fill in missing markers in real
time.
