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.
