IEEE Transactions on Multimedia, Vol. [3] prove that most of the loss functions are The findings are surprising: (1) data imbalance might not be an issue in learning high-quality representations; (2) with representations learned with the simplest instance-balanced (natural) … Learning from noisy labels with positive unlabeled learning. In addition to handling the unseen labels at test time, leveraging the co-occurrence information may also help in the standard multi-label learning setting, especially if the number of training examples is very small and/or the label matrix of training examples has a large fraction of missing entries. These pretext tasks involve transforming an image, computing a representation … In this work, we decouple the learning procedure into representation learning and classification, and systematically explore how different balancing strategies affect them for long-tailed recognition.

Weakly-supervised multi-label learning has received much attention more recently, and most of the existing methods focus on such problem with either missing or noisy labels, while the issue with both missing and noisy labels has not been well investigated. ∙ 0 ∙ share . The advantage of noise model-based methods is the label noise estimation and decoupling of classification, which helps them to work with the classification algorithm. in this setting. Existing self-supervised learning methods consist of creating a pretext task, for example, diving the images into nine patches and solving a jigsaw puzzle on the permuted patches. Learning With Auxiliary Less-Noisy Labels. However, the similarity of the outputs cannot guarantee the accuracy of target samples, i.e., target samples may match to wrong categories even if the discrepancy between two classifiers is small. ... the random forest method using a standard network traffic representation on all criteria considered. Label cleaning and pre-processing motivated to decouple the representation and classifier in noisy label learning. Given the importance of learning from such noisy labels, a great deal of practical work has been done on the problem (see, for instance, the survey article by Nettleton et al.

The advantage of noise model-based methods is the label noise estimation and decoupling of classification, which helps them to work with the classification algorithm. Since convolutional neural networks (ConvNets) can easily memorize noisy labels, which are ubiquitous in visual classification tasks, it has been a great challenge to train ConvNets against them robustly. Assistant Professor in the School of Interactive Computing at Georgia Tech and a member of the Machine Learning Center.Research interests include computer vision, machine learning, domain adaptation, robustness, and fairness. Specifically, in the first stage, inspired by the recent advances of self-supervised representation learning I've looked at things like "Learning from Massive Noisy Labeled Data for Image Classification", however they assume to learn some sort of noise covariace matrix … sive noisy testing data for evaluating a classifier's performance. The approach is generic and can be applied to similar networks where contextual cues are available at training time. ISBN: … We find that decoupling representation learning and classification has surprising results that challenge common beliefs for long-tailed recognition: instance-balanced sampling learns the best and most generalizable representations. Decoupling Representation and Classifier for Long-Tailed Recognition. Decoupling Representation and Classifier for Noisy Label Learning. We use the same categorization as in the previous section. An extensive survey about relatively old machine learning techniques under label noise is available [15], [16]. However, no work is proposed to provide a comprehensive survey on classification methods centered around deep learning in the presence of label noise. This work focuses explicitly on filling this absence. We represent these edges as a collection of parametric curves (i.e.,lines, circles, and B-splines). Our ultimate goal is to build agents with a human-like ability to generalize in real and diverse environments. The book chapter covers the historical development of machine learning with a focus on co … Authors: Hui Zhang, Quanming Yao. We construct a contrast learning scheme to modeling the inter-image separability and learn more discriminative embedding space to distinguish true common objects from noisy objects. Journal Papers.

[v1] A new prior is proposed for representation learning, which can be combined with other priors in order to help disentangling abstract factors from each other. To better han-dle label noise, some approaches rely on training classi-fiers with label noise-robust algorithms [4,15]. Unlike most existing sparse representation methods for SAR image classification, MSRC-JSDC learns a supervised sparse model from training samples by utilizing sample label … 2018-CVPR - CleanNet: Transfer Learning for Scalable Image Classifier Training with Label Noise. Unfortunately, noisy labels are ubiquitous in the real world. Our model is not dependent on any assumption of noise. However, Bartlett et al. A simple component that is effective in label noise correction, OOD sample removal, and representation learning. While numerous representation learning methods for static graphs have been proposed, the study of dynamic graphs is still in its infancy. SDCNL, which stands for Suicide Depression Classification with Noisy Labels, is a method for distinguishing between suicide and depression using deep learning and noisy label correction. In supervised learning of classifiers, having (random) errors in the labels of training examples is often referred to as label noise. To better han-dle label noise, some approaches rely on training classi-fiers with label noise-robust algorithms [4,15]. We’ll discuss a simple trick to deal with the case where we have positive examples only and unlabeled examples that could be either positive or negative (or have been heavily mislabeled and can be treated as unlabeled). 2019. ...
