Choice Functions, Digraphs, and Balanced Allocations
… this thesis, we consider broadly the concept of choice in a variety of settings, focusing on equity in selection. In particular, we introduce the concept of (pair-wise) domination graphs for hypergraphs endowed with a choice function on edges, and are interested, for instance, in minimal numbers …

Choice functions, dynamics, and equal representation
… study dynamics of systems evolving according to choice functions; such scenarios have the potential of being applicable in data and network processing, decision theory, and sampling. In particular, consider n linearly ordered size-one "spots" and k classes from which to fill the spots (where …

Characteristics of Fuzzy Social Choice Functions
… the strategic manipulation of fuzzy social choice functions where both individuals and groups can choose alternatives to various degrees. Past efforts to model fuzzy social choice and strategic manipulation have allowed individual preferences to be fuzzy but still required groups to select …

Sequential Decision Making For Choice Functions On Gambles
Choice functions on gambles (uncertain rewards) provide a framework for studying diverse preference and uncertainty models. For single decisions, applying a choice function is straightforward. In sequential problems, where the subject has multiple decision points, it is less easy. One possibility, …

Formal and philological inquiries into the nature of interrogatives, indefinites, disjunction, and focus in Sinhala and other languages
… be treated as uniformly denoting variables over choice functions which apply to the aforementioned Hamblin-type sets, thus ``restoring'' the derivation to normal Montagovian semantics. The treatment of Q-particles as uniformly denoting variables over choice functions provides an explanation for …

On the making and meaning of chains
… be allowed to range over pointwise different choice functions. Chapter 5 shows that quantification over individuals is insufficient, and that pointwise different choice functions are required. The result entails that the syntactic difference of A-chains and A-bar chains predicts a semantic …

Scope theory revisited : lessons from pied-piping in wh-questions
… 1973; Kratzer and Shimoyama, 2002; Cable, 2010), choice functions (Reinhart, 1997, 1998)) and adopting a richer representation of intensionality (e.g. in-situ binding of world/situation-denoting pronouns (Percus, 2000)). This thesis argues that a closer study of pied-piping in wh-questions reveals …

Unifying Optional Wh-movement
… particle Qu, which is seen to be a variable over choice functions, takes a wh-phrase as its complement to form a larger constituent. Second, it is proposed that the principle driving force of optional movement lies in the Featural Subset Hypothesis. The FSH proposes that the EPP is not parasitic …

Essays in organization formation and decision making
… in the model of Ghirardato et al. (2001). I use choice correspondences by lexicographic semiorders that are generalizations of the choice functions defined in Manzini and Mariotti (2012). I also provide a method constructing lexicographic semiorders for choosing from ambiguous acts.

Free groups and the axiom of choice
… are free. As all of its proofs use the Axiom of Choice, it is natural to ask whether the theorem is equivalent to the Axiom of Choice. Other questions arise in this context, such as whether the same is true for free abelian groups, and whether free groups have a notion of dimension in the absence …

Microeconomic Model Analyses
… machine learning models, with a wider margin as choices align more with an underlying preference ordering. The second chapter, joint with Professor Emel Filiz-Ozbay and Erkut Ozbay, empirically investigates the consideration and choice functions behaviors of individuals under uncertainty. Our …

Generative modeling of dynamic visual scenes
… classes of partial orders and consistent choice functions, a distribution over the spaces of partial orders is established, and inference can thus be performed thereon. The development of these models leads to significant challenges in probabilistic modeling and inference that need new …

Essays in group decision-making
… The second essay is in stochastic social choice theory. In a paper published in 1986 in Econometrica, Pattanaik and Peleg formulated stochastic analogues for each of Arrow's axioms and concluded that the stochastic social choice functions that satisfy their axioms are essentially randon …

Novel Neural Network Applications to Mode Choice in Transportation: Estimating Value of Travel Time and Modelling Psycho-Attitudinal Factors
… These models, often identified as discrete choice models (DCMs), usually require the definition of the utilities for each alternative, by first identifying the variables influencing the decisions. Traditionally, DCMs focused on observable variables and treated users as optimizing tools with …
