UCP-networks: A directed graphical representation of conditional utilities Conference Paper uri icon

abstract

  • Abstract We propose a directed graphical representation of utility functions, called UCP- networks, that combines aspects of two existing preference models: generalized additive models and CP-networks. The network decomposes a utility function into a number of additive factors, with the directionality of the arcs reflecting conditional dependence in the underlying (qualitative) preference ordering under a ceteris paribus interpretation. The CP- semantics ensures that computing optimization and dominance queries is very efficient …
