Q1. What are the contributions mentioned in the paper "Bi-capacities – part i: definition, möbius transform and interaction" ?
The aim of this paper in two parts is to present the machinery behind bicapacities, and thus remains on a rather theoretical level, although some parts are firmly rooted in decision theory, notably cooperative game theory. Then, the authors introduce derivatives of bi-capacities, by analogy with what was done for pseudoBoolean functions ( another view of capacities and set functions ), and this is the key point to introduce the Shapley value and the interaction index for bi-capacities. In summary, all familiar notions used for fuzzy measures are available in this more general framework.
