你好，请问在训练过程中会出现d_ap以及d_an逐渐增大，但是d_ap依然是小于d_an的，出现这样的情况是为什么呢？

d_ap小于d_an不是正常的吗

我的d_ap以及d_an逐渐减小，然后d_ap一直大于d_an，不知道为什么

我理解的是这样的：d_ap是应该小于d_an，但是训练过程中，感觉d_ap应该是越来越小才对，但现在在增大，虽然它的值还是小于d_an的。

我这边的训练集是文中提供的三个合并集进行训练，分别用Market1501，CUHK03，DukeMTMC-reID三个集去验证模型的map只有16.19, 11.178, 18.85，与文中相差很大，（参数与文中保持一致）
不知是我训练有错 或者 作者的指标是分别训练验证的
