Surprisingly Popular Voting Recovers Rankings, Surprisingly!

no code implementations19 May 2021 Hadi Hosseini, Debmalya Mandal, Nisarg Shah, Kevin Shi

A clever recent approach, \emph{surprisingly popular voting}, elicits additional information from the individuals, namely their \emph{prediction} of other individuals' votes, and provably recovers the ground truth even when experts are in minority.

Investigating the Characteristics of One-Sided Matching Mechanisms Under Various Preferences and Risk Attitudes

no code implementations1 Mar 2017 Hadi Hosseini, Kate Larson, Robin Cohen

One-sided matching mechanisms are fundamental for assigning a set of indivisible objects to a set of self-interested agents when monetary transfers are not allowed.

Random Serial Dictatorship versus Probabilistic Serial Rule: A Tale of Two Random Mechanisms

no code implementations4 Mar 2015 Hadi Hosseini, Kate Larson, Robin Cohen

For assignment problems where agents, specifying ordinal preferences, are allocated indivisible objects, two widely studied randomized mechanisms are the Random Serial Dictatorship (RSD) and Probabilistic Serial Rule (PS).
