Symmetric Cross Entropy for Robust Learning with Noisy Labels [] [] Yisen Wang*, Xingjun Ma*, Zaiyi Chen, Yuan Luo, Jinfeng Yi, James Bailey International Conference on Computer Vision (ICCV 2019), Seoul, Korea, 2019 8778–8788 (2018) Google Scholar To address this issue, we present a Context-Based Multi-LabelClassifier (CbMLC) that effectively handles noisy labels when learning label dependencies, without requiring additional supervision. ICCV, 2019. Here, we present a theoretically grounded set of noise-robust loss functions that can be seen as a generalization of MAE and CCE. knowledge distillation for noisy labels has also been proposed [23]. (1) Motivated by the memorization effects of deep networks, which shows networks fit clean instances first and then noisy ones, we present a new paradigm called "Co-teaching" combating with noisy labels. 2019年ICCV的一篇文章用这个“调换位置的交叉熵”（他们取名叫reverse cross entropy）来与经典的cross entropy loss加权得到一种Symmetric Loss function，用来解决label noise的问题。如果题主的文章中有这种noisy label（就是标签不准确）的可能性，可以考虑 In: Advances in Neural Information Processing Systems, pp. Learning with noisy labels总结Deep Label Distribution Learning With Label AmbiguityJoint Optimization Framework for Learning with Noisy Labels欢迎使用Markdown编辑器新的改变功能快捷键合理的创建标题，有助于目录的生成如何改变文本的样式插入链接与图片 Then, we introduce our proposed Taylor cross entropy loss.

(2018) trained an ensemble of classifiers on data with noisy labels using cross-validation and used the predictions of the ensemble as soft labels for training the final classifier. Symmetric Cross Entropy for Robust Learning With Noisy Labels: Already compared in our method. CleanNet, proposed by Lee et al. To distill the impact of noisy labels, the related work either filters out suspiciously noisy data, derives robust loss functions or tries to proactively correct labels. In this paper, we show that DNN learning with Cross Entropy (CE) exhibits overfitting to noisy labels on some classes ("easy" classes), but more surprisingly, it also suffers from significant under learning on some other classes ("hard" classes). @inproceedings{wang2019symmetric, title={Symmetric cross entropy for robust learning with noisy labels}, author={Wang, Yisen and Ma, Xingjun and Chen, Zaiyi and Luo, Yuan and Yi, Jinfeng and Bailey, James}, booktitle={IEEE International Conference on Proposed loss functions can be readily applied with any existing DNN architecture and algorithm, while yielding good performance in a wide range of noisy label scenarios. Training accurate deep neural networks (DNNs) in the presence of noisy labels is an important and challenging task. Robust loss minimization is an important strategy for handling robust learning issue on noisy labels. For some notional “clean” distribution D Learning robust deep models against noisy labels becomes ever critical when today's data is commonly collected from open platforms and subject to adversarial corruption. It is not only robust in learning with noisy labels, but also robust enough to apply in datasets with zero or small amount of potential label Generalized cross entropy loss for training deep neural networks with noisy labels Symmetric Cross Entropy for Robust Learning with Noisy Labels 这两篇是比较少的从构建新的损失函数的角度出发的解决噪音标签问题的论文（从我查到的情况下）。 Current robust loss functions , however, inevitably involve hyperparameter (s) to be tuned, manually or heuristically through cross validation, which makes them fairly hard to be generally applied in practice. , 2015 ), a large-scale clothing dataset by crawling im- robust learning with noisy labels. Our proposed SL approach simultaneously addresses both the under learning and overfitting problem of CE in the presence of noisy labels. presented a Symmetric cross entropy Learning (SL) approach, boosting Cross Entropy with a noise robust counterpart Reverse Cross Entropy. 3.1 Meta Transition Adaptation f or Robust Deep Learning with Noisy Labels ing Fig. 2.2 Learning with symmetric label noise (SLN learning) The problem of learning with symmetric label noise (SLN learning) is the following [Angluin and Laird,1988,Kearns,1998,Blum and Mitchell,1998,Natarajan et al.,2013]. Wang et al. O2U-Net: A Simple Noisy Label Detection Approach for Deep Neural Networks : It only requires adjusting the hyper-parameters of the deep network to make its status transfer from overfitting to underfitting (O2U) cyclically. Symmetric Cross Entropy for Robust Learning with Noisy Labels. In this talk, I will introduce two advanced and orthogonal techniques in deep learning with noisy labels, namely "training on selected samples" and "estimating the noise transition matrix".

Zhang and Sabuncu propose a generalized cross entropy loss for robust learning on noisy labels. Yisen Wang*, Xingjun Ma*, Zaiyi Chen, Yuan Luo, Jinfeng Yi, James Bailey; “Symmetric Cross Entropy for Robust Learning with Noisy Labels”, International Conference on … Though a number of approaches have been proposed for learning with noisy labels, many open issues remain. We compare CbMLC against other domain-specific state-of-the-art models on a variety of datasets, under both the clean and the noisy settings.

Pereyra et al. Iterative cross learning on noisy labels[6] 使用不同 子集的数据集训练网络，如果对于image的预测都相同，则该设置该image的label为这个预测，反之设置为任意值 Toward robustness against label noise in training deep discriminative neural networks[7]使用一种 graph-based的方法, noisy labels和clean labels之间的关系由条件随机场提取。 Inspired by the symmetric KL-divergence, we propose the approach of Symmetric cross entropy Learning (SL), boosting CE symmetrically with a noise robust counterpart Reverse Cross Entropy (RCE). Symmetric Cross For convenience, we assign 0 as the class label of samples belonging to background. (2018) , extracts a feature vector from a query image with a noisy label and compares it with a feature vector that is representative of its class. .. y i is the class label of the sample x i and can be noisy. hampers the performance of deep neural networks since the commonly used cross entropy loss is not noise-robust. Zhang, Z., Sabuncu, M.: Generalized cross entropy loss for training deep neural networks with noisy labels. Designing learning models that can robustly train on noisy labels is thus imperative. trained the DNN with Cross Entropy on soft labels instead of hard labels. Wang, Y., et al.

In this paper, we show that DNN learning with Cross Entropy (CE) exhibits overfitting to noisy labels on some classes (''easy' classes), but more surprisingly, it also suffers from significant under learning on some other classes (''hard' classes). ... empirically in the setting of deep learning from noisy labels. Learning with Noise Transition Goldberger and Ben-Reuven (2017) proposed to model the noise transition by adding an additional linear layer on top of the neural network that connects the correct labels to the noisy ones.
