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. However, because the targets change only once per epoch, … WebNov 19, 2024 · Mean Teacher学习笔记（一）模型的核心思想：模型即充当学生，又充当老师。作为老师，用来产生学生学习时的目标，作为学生，利用老师模型产生的目标来学习。为了克服Temporal Ensembling的局限性，我们建议平均模型权重而不是预测。教师模式是连续学生模式的平均值，因此我们叫它Mean teacher。
