Developing robust algorithms and theory for establishing cause-effect relationships from observational data that scale up to large data sets

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…
