Web而Mean-Teacher是每个mini-batch的更新都对整个model进行ensemble,直觉上效率更高。. weighted average的是整个model params,因此不仅是final layer的output被EMA,中间所有的layer都被EMA,因此Mean-Teacher拥有更好的intermediate representation,可以理解为中间的hidden representation更加robust吧 ...
WebMar 19, 2024 · 个人认为,Mean Teacher网络的训练是一个求同存异的过程,输入的图像略有差异,网络参数略有差异,我们假设网络训练好后完全收敛,此时学生网络和教师网络的参数应该是非常接近的,也具备良好的去噪能力,那么一致性损失就会很小;自监督学习先使用大量无标签的数据集,通过对比学习和图像 ... WebMar 6, 2024 · The recently proposed Temporal Ensembling has achieved state-of-the-art results in several semi-supervised learning benchmarks. It maintains an exponential moving average of label predictions on each training example, and penalizes predictions that are inconsistent with this target.
