我不是很熟悉 YOLO v3.
AFF 的 Motivation 大致是用 Attention 来替换网络中原有的 Addition 和 Concat,这个 Addition 和 Concat 可以是分类网络 Backbone 里的,也可以是检测、分割网络(FPN、U-Net)里的跨层、多层融合之间的。
如果是我的话,我会先拿您给的截图中的跨层融合的 Concat 替换成 AFF。期待您的进一步反馈。
很抱歉回复晚了,最近几天一直在外面奔波,没有坐到电脑前的机会。

我在语义分割实验里是加到 FPN 的跨层融合里的,也算 Backbone 的最后吧,效果可以的。
但如果只在 Backbone 的最后用一次的话,我觉得上更复杂、更强大的 Attention 模块可能 Feature Refinement 的效果会更好,MS-CAM 还是有点轻量级,当然您可以增加更多的尺度使其变得更加 heavy,也能抓住更多尺度的特征。

非常感谢您的回复,我试试看。

打扰您了,想问一下,如果把MS-CAM加入到yolov3中,插入到图中哪个位置效果可能比较好些呢?
