TL;DR该论文提出了一种基于多粒度对齐的检测框架,不仅考虑了不同类别实例之间的区别,还考虑了不同领域中不同粒度样本的区别,并采用自适应指数移动平均策略 for model assessment 来提高检测的鲁棒性。
Abstract
domain adaptive detection aims to improve the generalization of detectors on target domain. To reduce discrepancy in feature distributions between two domains, recent approaches achieve domain adaption through feature a
