learner is presented with a context set of $ K $ items, chosen randomly from a potentially …

Route choice in multimodal networks shows a considerable variation between different

This paper studies the problem of rank aggregation under the Plackett-Luce model. The goal

Group decision making is an important, long‐standing, and ubiquitous problem in all
societies, where collective decisions must be made by a group of agents despite individual …

Rank breaking is a methodology introduced by Azari Soufiani et al.(2013a) for applying a
Generalized Method of Moments (GMM) algorithm to the estimation of parametric ranking …

Virtual democracy is an approach to automating decisions, by learning models of the
preferences of individual people, and, at runtime, aggregating the predicted preferences of …

Data in the form of pairwise comparisons arises in many domains, including preference
elicitation, sporting competitions, and peer grading among others. We consider parametric …
