摘要:

提出了一种基于半监督学习的视觉属性预测方法。在视觉算法的许多应用中,物体视觉属性的精确识别是重要的,但仍然具有挑战性。这是因为定义属性的类层次结构是模糊的,因此训练数据不可避免地遭受类不平衡和标签稀疏,导致缺乏有效的注释。一个直观的解决方案是找到一种方法,通过利用未标记的图像来有效地学习图像表示。考虑到这一点,我们提出了一个多教师-单学生(MTSS)的方法,灵感来自多任务学习和半监督学习的升华。我们的MTSS使用标签嵌入技术学习特定于任务的领域专家,称为教师网络,并通过强制模型模仿领域专家学习的分布来学习称为学生网络的统一模型。我们的实验表明,我们的方法不仅在各种时尚属性预测的基准测试中取得了有竞争力的性能,而且还提高了对未知领域的鲁棒性和跨领域适应性。

英文摘要:

This paper presents a study on semi-supervised learning to solve the visual attribute prediction problem. In many applications of vision algorithms, the precise recognition of visual attributes of objects is important but still challenging. This is because defining a class hierarchy of attributes is ambiguous, so training data inevitably suffer from class imbalance and label sparsity, leading to a lack of effective annotations. An intuitive solution is to find a method to effectively learn image representations by utilizing unlabeled images. With that in mind, we propose a multi-teacher-single-student (MTSS) approach inspired by the multi-task learning and the distillation of semi-supervised learning. Our MTSS learns task-specific domain experts called teacher networks using the label embedding technique and learns a unified model called a student network by forcing a model to mimic the distributions learned by domain experts. Our experiments demonstrate that our method not only achieves competitive performance on various benchmarks for fashion attribute prediction, but also improves robustness and cross-domain adaptability for unseen domains.
