Well done. You've clicked the tower. This would actually achieve something if you had logged in first. Use the key for that. The name takes you home. This is where all the applicables sit. And you can't apply any changes to my site unless you are logged in.

Our policy is best summarized as "we don't care about _you_, we care about _them_", no emails, so no forgetting your password. You have no rights. It's like you don't even exist. If you publish material, I reserve the right to remove it, or use it myself.

Don't impersonate. Don't name someone involuntarily. You can lose everything if you cross the line, and no, I won't cancel your automatic payments first, so you'll have to do it the hard way. See how serious this sounds? That's how serious you're meant to take these.

Over the last years, significant advances have been made in robotic
manipulation, but still, the handling of non-rigid objects, such as cloth
garments, is an open problem. Physical interaction with non-rigid objects is
uncertain and complex to model. Thus, extracting useful information from sample
data can considerably improve modeling performance. However, the training of
such models is a challenging task due to the high-dimensionality of the state
representation. In this paper, we propose Controlled Gaussian Process Dynamical
Model (CGPDM) for learning high-dimensional, nonlinear dynamics by embedding it
in a low-dimensional manifold. A CGPDM is constituted by a low-dimensional
latent space, with an associated dynamics where external control variables can
act and a mapping to the observation space. The parameters of both maps are
marginalized out by considering Gaussian Process (GP) priors. Hence, a CGPDM
projects a high-dimensional state space into a smaller dimension latent space,
in which it is feasible to learn the system dynamics from training data. The
modeling capacity of CGPDM has been tested in both a simulated and a real
scenario, where it proved to be capable of generalizing over a wide range of
movements and confidently predicting the cloth motions obtained by previously
unseen sequences of control actions.
