Center node: "weighted sets of probabilities and minimaxweighted expected regret new approaches for representing uncertainty and making decisions"
  Abstract: We consider a setting where an agent's uncertainty is represented by a set of probability measures, rather than a single measure. Measure-bymeasure updating of such a set of measures upon acquiring new information is well-known to suffer from problems; agents are not always able to learn appropriately. To deal with these problems, we propose using weighted sets of probabilities: a representation where each measure is associated with a weight, which denotes its significance. We describe a natural approach to updating in such a situation and a natural approach to determining the weights. We then show how this representation can be used in decision-making, by modifying a standard approach to decision making-minimizing expected regret-to obtain minimax weighted expected regret (MWER).We provide an axiomatization that characterizes preferences induced by MWER both in the static and dynamic case.

Connected through hyperedge HE-1 (induced by source paper "weighted regret based likelihood a new approach to describing uncertainty"):

    - "do we need higher order probabilities and if so what do they mean"
    - "calculating uncertainty intervals from conditional convex sets of probabilities"
