WebAug 24, 2024 · The introduced positive pair weighting strategy enables the algorithm to focus more on the hard positive samples. Furthermore, we propose to enhance the proposed loss function by adding a global loss term to reduce the variances of positive/negative pair distances, which is able to improve the generalization capability of the network model. WebA weighting vector can be created from pairwise preference assessments. This technique was introduced by Saaty in 1980 when he developed the analytic hierarchy process that we’ll study in Section 8.4.
