This paper introduces a novel approach for learning to rank (LETOR) based on
the notion of monotone retargeting. It involves minimizing a divergence between
all monotonic increasing transformations of the trainin
Pairwise Differentiable Gradient Descent (PDGD) is an efficient and unbiased Online Learning to Rank approach that allows for effective optimization of non-linear models based on user interactions and preferences, providing a better user experience than previously possible.
