论文摘要

最近,视频识别是在多模式学习的帮助下出现的,该学习重点是整合不同的模式以提高模型的性能或鲁棒性。尽管已经提出了各种多模式学习方法并提供了显着的识别结果,但几乎所有这些方法都依赖于高质量的手动注释,并假设多模式数据之间的模态提供了语义相关的信息。不幸的是,使用广泛使用的视频数据集通常是从互联网上进行粗声或收集的。因此,它不可避免地包含一部分嘈杂的标签和嘈杂的对应关系。为了应对这一挑战,我们将视听动作识别任务用作代理,并提出了一个耐噪声的学习框架,以找到针对嘈杂标签和嘈杂对应的反干扰模型参数。具体而言,我们的方法包括两个阶段,旨在通过模态之间的固有相关性来纠正噪声。首先,执行了具有噪声的对比训练阶段,以使该模型免疫可能的嘈杂标记数据。为了减轻嘈杂对应关系的影响,我们提出了一个跨模式噪声估计成分,以调整不同方式之间的一致性。随着嘈杂的对应关系在实例级别上,我们进一步提出了类别级的对比损失,以减少其干扰。其次,在混合监督训练阶段,我们计算特征之间的距离度量,以获得校正的标签,这些标签被用作指导训练的互补监督。广泛的嘈杂水平的广泛实验表明,我们的方法显着提高了动作识别模型的鲁棒性,并超过了基线的明显边缘。

Recently, video recognition is emerging with the help of multi-modal learning, which focuses on integrating distinct modalities to improve the performance or robustness of the model. Although various multi-modal learning methods have been proposed and offer remarkable recognition results, almost all of these methods rely on high-quality manual annotations and assume that modalities among multi-modal data provide semantically relevant information. Unfortunately, the widely used video datasets are usually coarse-annotated or collected from the Internet. Thus, it inevitably contains a portion of noisy labels and noisy correspondence. To address this challenge, we use the audio-visual action recognition task as a proxy and propose a noise-tolerant learning framework to find anti-interference model parameters against both noisy labels and noisy correspondence. Specifically, our method consists of two phases that aim to rectify noise by the inherent correlation between modalities. First, a noise-tolerant contrastive training phase is performed to make the model immune to the possible noisy-labeled data. To alleviate the influence of noisy correspondence, we propose a cross-modal noise estimation component to adjust the consistency between different modalities. As the noisy correspondence existed at the instance level, we further propose a category-level contrastive loss to reduce its interference. Second, in the hybrid-supervised training phase, we calculate the distance metric among features to obtain corrected labels, which are used as complementary supervision to guide the training. Extensive experiments on a wide range of noisy levels demonstrate that our method significantly improves the robustness of the action recognition model and surpasses the baselines by a clear margin.
