Parametric representation of preferences
A preference is invariant with respect to a transformation τ if its ranking of acts is unaffected by a reshuffling of the states under τ . We show that any invariant preference must be parametric: there is a unique sufficient set of parameters such that the preference ranks acts according to their expected utility given the parameters. This property holds for all non-trivial preferences, provid...
متن کاملA Non-Parametric Test of Stochastic Preferences
In this paper we present algorithms to test a theory of stochastic preferences on binary choice data. For the general case, where preferences can be any strict linear order, a column generation algorithm is given. This algorithm can be easily adjusted to test for specific classes of preferences or to account for different kinds of data. We perform preliminary experiments showing the viability o...
متن کاملUtility representation of lower separable preferences
Topological separability is crucial for the utility representation of a complete preference relation. When preferences are incomplete, this axiom has suitably de ned counterparts: upper separability and lower separability (Ok (2002)). We consider the problem of representing an incomplete preference relation by means of a vector-valued utility function; we obtain representation results under the...
متن کاملParametric representation of “critical” noncommutative QFT models
We extend the parametric representation of renormalizable non commutative quantum field theories to a class of theories which we call “critical”, because their power counting is definitely more difficult to obtain.This class of theories is important since it includes gauge theories, which should be relevant for the quantum Hall effect.
متن کاملTowards an MDD-based Representation of Preferences
The last decade witnessed a considerable number of compact representations of knowledge (beliefs or preferences) which encode an ordering relation (partial/total (pre)orders) over a set of outcomes. The need for such representations is motivated by two main reasons: (1) the set of outcomes is generally exponential which causes problems from representational and spacial points of view, and (2) i...
