Income Rank and Upward Comparisons
Many studies have argued that relative income predicts individual well-being. More recently, it has been suggested that the relative rank of an individual’s income, rather than how that income compares to a mean or reference income, is important. Here the relative rank hypothesis is examined along with the additional hypothesis that individuals compare their incomes predominantly with those of ...
متن کاملRank Centrality: Ranking from Pairwise Comparisons
The question of aggregating pairwise comparisons to obtain a global ranking over a collection of objects has been of interest for a very long time: be it ranking of online gamers (e.g. MSR’s TrueSkill system) and chess players, aggregating social opinions, or deciding which product to sell based on transactions. In most settings, in addition to obtaining a ranking, finding ‘scores’ for each obj...
متن کاملActive Learning for Top-K Rank Aggregation from Noisy Comparisons
We explore an active top-K ranking problem based on pairwise comparisons that are collected possibly in a sequential manner as per our design choice. We consider two settings: (1) top-K sorting in which the goal is to recover the top-K items in order out of n items; (2) top-K partitioning where only the set of top-K items is desired. Under a fairly general model which subsumes as special cases ...
متن کاملSpectral MLE: Top-K Rank Aggregation from Pairwise Comparisons
This paper explores the preference-based top-K rank aggregation problem. Suppose that a collection of items is repeatedly compared in pairs, and one wishes to recover a consistent ordering that emphasizes the top-K ranked items, based on partially revealed preferences. We focus on the Bradley-Terry-Luce model that postulates a set of latent preference scores underlying all items, where the odds...
متن کاملHigher rank Einstein solvmanifolds
In this paper we study the structure of standard Einstein solvmanifolds of arbitrary rank. Also the validity of a variational method for finding standard Einstein solvmanifolds is proved.
