essentially human characteristics that are difficult to capture computationally
in open-domain problems. However, QoI characteristics may provide a
basis for deriving a probabilistic VoI to be used in transactional (nonclairvoy-
ant) estimates. Further, it may be feasible to learn over QoI values to bound a
purely computational VoI. Future research, building on our work, may war-
rant additional consideration about how machine-learned QoI could trans-
late to a functional VoI.
