An Offline Metric for the Debiasedness of Click Models

2 code implementations19 Apr 2023 Romain Deffayet, Philipp Hager, Jean-Michel Renders, Maarten de Rijke

We prove that debiasedness is a necessary condition for recovering unbiased and consistent relevance scores and for the invariance of click prediction under covariate shift.
