WebFeb 7, 2024 · In this paper we introduce a geometrical object, a polytope that we call expohedron, whose points represent all achievable exposures of items for a Position Based Model (PBM). We exhibit some of its properties and lay out a Carathéodory decomposition algorithm with complexity O(n^2log(n)) able to express any point inside the expohedron … WebWelcome to a supernatural expo like no other!
