Distributionally Robust Optimization with Infinitely Constrained Ambiguity Sets

We consider a distributionally robust optimization problem where the ambiguity set of probability distributions is characterized by a tractable conic representable support set and expectation constraints. Specifically, we propose and motivate a new class of infinitely constrained ambiguity sets in which the number of expectation constraints could potentially be infinite. We show how the infinit...

Polymorphism as a Model for Ambiguity in Natural Language

We suggest modeling concepts as types in a strongly-typed ontology that reflects our commonsense view of the world and the way we talk about it in ordinary language. In such a framework, certain types of ambiguities in natural language are explained by the notion of polymorphism. In this paper we suggest such a typed compositional semantics for nominal compounds of the form (Adj Noun) where adj...

Ambiguity and Ambiguity Aversion

Consider the following choice problem, known as “Ellsberg’s three-color urn example”, or simply the “Ellsberg Paradox” (Ellsberg [7]). An urn contains 30 red balls, and 60 green and blue balls, in unspecified proportions; subjects are asked to compare (i) a bet on a red draw vs. a bet on a green draw, and (ii) a bet on a red or blue draw vs. a bet on a green or blue draw. If the subject wins a ...

Semantic Ambiguity and Perceived Ambiguity

I explore some of the issues that arise when trying to establish a connection between the underspecification hypothesis pursued in the NLP literature and work on ambiguity in semantics and in the psychological literature. A theory of underspecification is developed ‘from the first principles’, i.e., starting from a definition of what it means for a sentence to be semantically ambiguous and from...

Differentiating ambiguity and ambiguity attitude

The objective of this paper is to show how ambiguity, and a decision maker (DM)’s response to it, can be modelled formally in the context of a general decision model. We introduce a relation derived from the DM’s preferences, called ‘‘unambiguous preference’’, and show that it can be represented by a set of probabilities. We provide such set with a simple differential characterization, and argu...
