论文摘要
在本文中,我们介绍了顾问网络的新颖概念,以解决图像分类中嘈杂标签的问题。深层神经网络(DNN)容易降低性能和嘈杂注释的培训数据中的过度拟合问题。加权损失方法旨在减轻训练期间嘈杂标签的影响,从而完全消除其贡献。这种丢弃的过程阻止DNN在图像及其正确标签之间学习错误的关联,但减少了所使用的数据量,尤其是当大多数样本具有嘈杂的标签时。从不同方面来看,我们的方法权衡了直接从分类器提取的功能,而不会更改每个数据的损耗值。该顾问仅专注于错误标签示例中存在的某些信息,从而使分类器也可以利用该数据。我们通过元学习策略对其进行了培训,以便它可以在整个主要模型的培训中进行适应。我们使用合成噪声测试了CIFAR10和CIFAR100的方法,并在包含现实世界噪声的Clothing1m上测试了我们的方法,报告了最新的结果。
In this paper, we introduced the novel concept of advisor network to address the problem of noisy labels in image classification. Deep neural networks (DNN) are prone to performance reduction and overfitting problems on training data with noisy annotations. Weighting loss methods aim to mitigate the influence of noisy labels during the training, completely removing their contribution. This discarding process prevents DNNs from learning wrong associations between images and their correct labels but reduces the amount of data used, especially when most of the samples have noisy labels. Differently, our method weighs the feature extracted directly from the classifier without altering the loss value of each data. The advisor helps to focus only on some part of the information present in mislabeled examples, allowing the classifier to leverage that data as well. We trained it with a meta-learning strategy so that it can adapt throughout the training of the main model. We tested our method on CIFAR10 and CIFAR100 with synthetic noise, and on Clothing1M which contains real-world noise, reporting state-of-the-art results.
