Listwise approach
Web6 mrt. 2024 · Listwise approach These algorithms try to directly optimize the value of one of the above evaluation measures, averaged over all queries in the training data. This is difficult because most evaluation measures are not continuous functions with respect to ranking model's parameters, and so continuous approximations or bounds on evaluation … WebSuch listwise approaches have also been used for information aggregation in other NLP tasks such as question answering (Wang et al.,2024;Nie et al.,2024b). At a high level, this strategy suffers from a number of challenges, including data sparsity and a high level of sensitivity to noisy inputs. Following this thread of work, we adopt the ...
