In this paper, we propose a framework for learning the pa- rameters of registration cost functions – such as the tradeoff between the regularization and image similarity term – with respect to a specific task. Assuming the existence of labeled training data, we specialize the framework for the...
We conduct an experiment where participants make choices between completing a task now or waiting to complete it in the future. We vary the dates when a task can be completed and the effort required at each date. We infer participants' preferences for when to complete a task and their expect...
