针对多任务部分标注数据的利用问题,提出采用知识蒸馏实现目标检测与语义分割的联合任务优化,实验证明该方法效果优于单任务学习及全监督场景,并开源了代码与数据划分。

摘要:

若网络能利用任务间关联,每个数据点仅标注单个任务的多任务部分标注数据或可缓解数据稀缺问题。本文研究从部分标注的多任务数据中联合学习目标检测与语义分割这两大最主流的视觉任务。我们开展了大量实验,评估各任务性能,并探究多任务网络无法同时优化两个任务时二者的互补性。我们提出采用知识蒸馏(knowledge distillation)来实现联合任务优化。实验结果表明,多任务学习结合知识蒸馏的效果优于单任务学习,甚至优于全监督场景。所有代码和数据划分可在https://github.com/lhoangan/multas 获取。

英文摘要:

Multi-task partially annotated data where each data point is annotated for only a single task are potentially helpful for data scarcity if a network can leverage the inter-task relationship. In this paper, we study the joint learning of object detection and semantic segmentation, the two most popular vision problems, from multi-task data with partial annotations. Extensive experiments are performed to evaluate each task performance and explore their complementarity when a multi-task network cannot optimize both tasks simultaneously. We propose employing knowledge distillation to leverage joint-task optimization. The experimental results show favorable results for multi-task learning and knowledge distillation over single-task learning and even full supervision scenario.
