$\ell_∞$-Bounds of the MLE in the BTL Model under General Comparison Graphs

UAI 2022poster

The Bradley-Terry-Luce (BTL) model is a popular statistical approach for estimating the global ranking of a collection of items using pairwise comparisons. To ensure accurate ranking, it is essential to obtain precise estimates of the model parameters in the $\ell_{\infty}$-loss. The difficulty of t…

Nonparametric Estimation in the Dynamic Bradley-Terry Model

AISTATS 2020poster

We propose a time-varying generalization of the Bradley-Terry model that allows for nonparametric modeling of dynamic global rankings of distinct teams. We develop a novel estimator that relies on kernel smoothing to pre-process the pairwise comparisons over time and is applicable in sparse settings…
