Pairwise margin ranking loss
Webdirectional hard-negatives ranking loss. The positive pair is the same location in the both cases, while the hardest negative exam-ple are at different distance. The case on the left has higher loss with the bi-directional max-margin ranking loss compared to right. The bi-directional hard-negatives ranking loss assigns a higher loss WebDec 3, 2024 · Although the complete computation of deep large-margin rank loss function has the O(C2) time complexity, where C denotes the size of the label set, which would cause scalability issues when C is large, a negative sampling technique was proposed to make the loss function scale linearly to C. Experimental results on two large-scale datasets, …

WebOct 6, 2024 · The target is to minimize the pairwise ranking loss \(Los{s_G}\) for all QA pairs in the G-net and to allow the model to learn discriminative features that distinguish QA pairs. As the gradient passes through thr GRL, the gradient is changed to the opposite direction, which enables the G-BERT to extract common features of passages to a given query.
