Practitioners often use data from a randomized controlled trial to learn a treatment assignment policy that can be deployed on a target population.

Applying the distributionally robust optimization framework, we propose a method for learning a decision rule that minimizes the worst-case risk incurred under a family of test distributions that can generate the training distribution under $\Gamma$-biased sampling.

Decision makers often aim to learn a treatment assignment policy under a capacity constraint on the number of agents that they can treat.

We propose a stronger notion of calibration called threshold calibration, which is exactly the condition required to ensure that decision loss is predicted accurately for threshold decisions.

In this work, we introduce a new notion -- \emph{decision calibration} -- that requires the predicted distribution and true distribution to be ``indistinguishable'' to a set of downstream decision-makers.

Current unsupervised domain adaptation methods can address many types of distribution shift, but they assume data from the source domain is freely available.

Reasoning about uncertain orientations is one of the core problems in many perception tasks such as object pose estimation or motion estimation.
