Machine Learning for Control
This research thrust is developing novel methods for learning from demonstration using model learning that generates robot paths and motions. The research creates learning algorithms that develop re-usable models (mostly in the form of differential equations) and controls that contains properties such as stability, safety and robustness observed in data.
