Fairness in Ranking under Uncertainty

1 code implementation NeurIPS 2021 Ashudeep Singh, David Kempe, Thorsten Joachims

We call an algorithm $\phi$-fair (for $\phi \in [0, 1]$) if it has the following property for all agents $x$ and all $k$: if agent $x$ is among the top $k$ agents with respect to merit with probability at least $\rho$ (according to the posterior merit distribution), then the algorithm places the agent among the top $k$ agents in its ranking with probability at least $\phi \rho$.
