摘要:

我们研究了全监督学习,一种特殊的半监督学习机制,其中学习者利用所有可用的标记数据加上互联网规模的未标记数据源。全方位监督学习在现有标记数据集上的性能下限,提供了超越最先进的全监督方法的潜力。为了利用全监督设置,我们提出了数据蒸馏,这是一种使用单个模型集成来自未标记数据的多个变换的预测的方法,以自动生成新的训练注释。我们认为,视觉识别模型最近已经变得足够准确,现在可以将关于自我训练的经典思想应用于挑战现实世界的数据。我们的实验结果表明,在人体关键点检测和一般目标检测的情况下,使用数据蒸馏训练的最先进的模型超过了单独使用COCO数据集的标记数据的性能。

英文摘要:

We investigate omni-supervised learning, a special regime of semi-supervised learning in which the learner exploits all available labeled data plus internet-scale sources of unlabeled data. Omni-supervised learning is lower-bounded by performance on existing labeled datasets, offering the potential to surpass state-of-the-art fully supervised methods. To exploit the omni-supervised setting, we propose data distillation, a method that ensembles predictions from multiple transformations of unlabeled data, using a single model, to automatically generate new training annotations. We argue that visual recognition models have recently become accurate enough that it is now possible to apply classic ideas about self-training to challenging real-world data. Our experimental results show that in the cases of human keypoint detection and general object detection, state-of-the-art models trained with data distillation surpass the performance of using labeled data from the COCO dataset alone.
