Aggregation of pairwise comparisons with reduction of biases

no code implementations9 Jun 2019 Nadezhda Bugakova, Valentina Fedorova, Gleb Gusev, Alexey Drutsa

Answers to pairwise tasks are known to be affected by the position of items on the screen, however, previous models for aggregation of pairwise comparisons do not focus on modeling such kind of biases.
