Intervention Harvesting for Context-Dependent Examination-Bias Estimation

no code implementations5 Nov 2018 Zhichong Fang, Aman Agarwal, Thorsten Joachims

To overcome this limitation, we propose a Contextual Position-Based Model (CPBM) where the examination bias may also depend on a context vector describing the query and the user.

Consistent Position Bias Estimation without Online Interventions for Learning-to-Rank

no code implementations9 Jun 2018 Aman Agarwal, Ivan Zaitsev, Thorsten Joachims

Presentation bias is one of the key challenges when learning from implicit feedback in search engines, as it confounds the relevance signal with uninformative signals due to position in the ranking, saliency, and other presentation factors.

A General Framework for Counterfactual Learning-to-Rank

no code implementations30 Apr 2018 Aman Agarwal, Kenta Takatsu, Ivan Zaitsev, Thorsten Joachims

Specifically, we derive a relaxation for propensity-weighted rank-based metrics which is subdifferentiable and thus suitable for gradient-based optimization.
