There is a general agreement that it is important to consider the practical relevance of an effect in addition to its statistical significance, yet a formal definition of practical…
Information efficient learning of complexly structured preferences: Elicitation procedures and their application to decision making under uncertainty
Christoph Jansen, Hannah Blocher, Thomas Augustin +1
In this paper we propose efficient methods for elicitation of complexly structured preferences and utilize these in problems of decision making under (severe) uncertainty. Based on…
