Branding has become one of the most important determinants of consumer choices. Intriguingly, the psychological mechanisms of how branding influences decision making remain elusive. In the research reported here, we used a preference-based decision-making task and computational modeling to identify which internal components of processing are affected by branding. We found that a process of nois...

Product search is an emerging search application where optimization of search results relies critically on an accurate model of a user’s price preference. In this paper, we propose a Bayesian framework for modeling a user’s price preference with a particular focus on developing a smart price filter model for inferring a user’s price preference based on the user’s selection of price filters and ...

One of the fundamental phenomena in life concerns the notion of a preference. Preferences are a central concept in decision making. Accordingly, the complexity of preference reasoning has challenged researchers from diverse disciplines ever since. During the past decade also in database systems this topic has emerged into a flourishing field. This talk will address several achievements that hav...

Personalization of e-services poses new challenges to database technology, demanding a powerful and flexible modeling technique for complex preferences. Preference queries have to be answered cooperatively by treating preferences as soft constraints, attempting a best possible match-making. We propose a strict partial order semantics for preferences, which closely matches people’s intuition. A ...

This paper is devoted to construction of fuzzy preference relations and to showing how this construction is connected with Lukasiewicz filters and TL-evaluators. We will study also extensions of Lukasiewicz filters on subsets of some X 6= ∅ to TL-evaluators on the system (lattice) of fuzzy functions f : X → [0, 1].

In decision making, in order to avoid misleading solutions, the study of consistency when the decision makers express their opinions by means of preference relations becomes a very important aspect in order to avoid misleading solutions. In decision making problems based on fuzzy preference relations the study of consistency is associated with the study of the transitivity property. In this pap...

Stochastic trees are semi-Markov processes represented using tree diagrams. Such trees have been found useful for prescriptive modeling of temporal medical treatment choice. We consider utility functions over stochastic trees which permit recursive evaluation in a graphically intuitive manner analogous to decision tree rollback. Such rollback is computationally intractable unless a low-dimensio...

We investigate the impact of a non-financial background risk ε̃ on the preference rankings between two independent financial risks z̃1 and z̃2 for an expected-utility maximizer. More precisely, we provide necessary and sufficient conditions for the alternative (x0 + z̃1, y0 + ε̃) to be preferred to (x0 + z̃2, y0 + ε̃) whenever (x0 + z̃1, y0) is preferred to (x0 + z̃2, y0). Utility functions that preserv...
