在学习的时候,Quad-CNN联合了检测结果的外观和特定序列中能够感知运动的位置。 ②使用一种multi-task loss来联合学习目标关联和Bbox回归,整个的网络在一个统一的框架中被端到端的训练。 ③采用一种修改过的minimax label propagation算法来做快速且鲁棒的数据关联。

we design a quadruplet loss, which can lead to the model output with a larger inter-class variation and a smaller intra-class variation compared to the triplet loss. As a result, our model has a better generalization ability and can achieve a higher performance on the testing set. In parti...
quadruple(adj.) "consisting of four parts, fourfold, four times told," 1550s, from Frenchquadruple(13c.), from Latinquadruplus"fourfold," fromquadri-"four" (from PIE root*kwetwer-"four") +-plus"-fold" (see-plus). Earlier in English as a noun, "a fourfold amount," early 15c., ...
In particular, a quadruplet deep network using a margin-based online hard negative mining is proposed based on the quadruplet loss for the person ReID. In extensive experiments, the proposed network outperforms most of the state-of-the-art algorithms on representative datasets which ...
At the loss level, a multi-view quadruplet loss operating on the representations of quadruplets is proposed to reduce the intra-class distances caused by view variations and increase the inter-class distances of baggage images captured in the same view. A random local blur data augmentation is ...
其中loss_i^n 就是triplet loss;f(x, y)的值域为[0, 2],值越大代表越不相似。 上述损失函数的目的是:让q与正样本的距离变小,让q与simple负样本的距离变大,让hard负样本与simple负样本的距离变大。从而让正样本和q的距离比较小,同时让正样本和hard负样本远离simple负样本。 2.5 hard negative如何获得 在...

Contraindications for DID are fetal distress, congenital abnormalities, preterm rupture of membranes of the remaining fetus, chorioamnionitis, suspected placental abruption, and severe vaginal blood loss. Gestational age and chorionicity suitable for DID are ...
