Learning to Learn from Noisy Labeled Data. To tackle this problem, some image related side information, such as captions and tags, often reveal underlying relationships across images. ... Training on noisy labeled datasets causes performance degradation because DNNs can easily overfit to the label noise. (2) ... Another body of work that is relevant to our problem is learning with noisy labels where usual assumption is that all the labels are generated through the same noisy rate given their ground truth label. Supervised learning depends on annotated examples, which are taken to be the \\emph{ground truth}. Breast tumor classification through learning from noisy labeled ultrasound images. There exist many inexpensive data sources on the web, but they tend to contain inaccurate labels. Conclusion and future work • We addressed the problem of learning a classifier from noisy label distributions • There is no labeled data • Instead, each instance belongs to more than one groups, and then, each group has a noisy label distribution • To solve this problem, we proposed a probabilistic generative model • Future work • Experiments on real-world datasets 26 Right: a meta-learning update is performed beforehand using synthetic label noise, which encourages the network parameters to be noise-tolerant and reduces overfitting during the conventional update.

Despite the success of deep neural networks (DNNs) in image classification tasks, the human-level performance relies on massive training data with high-quality manual annotations, which are expensive and time-consuming to collect. Learning from noisy labels with positive unlabeled learning. That is without meta-learning on synthetic noisy examples. We perform a detailed inves-tigation of this problem under two realistic noise models and propose two algorithms to learn from noisy S-D data. Learning From Noisy Singly-labeled Data. for Information Science and Technology Dept. : “A Data-Driven Analysis of Workers’ Earnings on Amazon Mechanical Turk”, CHI 2018. distribution; learning from only positive and unlabeled data [Elkan and Noto, 2008] can also be cast in this setting. An assumption of XPRESS (and of the noise tolerant learning approach) is that noisy labeled data is available in abundance. This model predicts the relevance of an image to its noisy class label. In this work, we propose an improved joint optimization framework for noise correction, which uses the Combination of Mix-up entropy and Kullback-Leibler entropy (CMKL) as the loss function. However, in this case, the baseline should be Iterative training without Meta-learning.

Then from the mass of data that we have collected we want to learn the patterns of transactions that can be used to predict fraud. [26] enforce the network trained from the noisy data to imitate the behavior of another network learned from the clean set. Request PDF | On Jun 1, 2019, Junnan Li and others published Learning to Learn From Noisy Labeled Data | Find, read and cite all the research you need on ResearchGate In many real-world datasets, like WebVision, the performance of DNN based classifier is often limited by the noisy labeled data. However, obtaining a massive amount of well-labeled data is usually very expensive and time consuming. CVPR 2019 • LiJunnan1992/MLNT • Despite the success of deep neural networks (DNNs) in image classification tasks, the human-level performance relies on massive training data with high-quality manual annotations, which are … Note that label noise detection not only is useful for training image classifiers with noisy data, but also has important values in applications like image search result filtering and linking images to knowledge graph entities. Supervised learning depends on annotated examples, which are taken to be the \emph{ground truth}. demonstrate how to learn a classifier from noisy S and D labeled data. 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. But these labels often come from noisy crowdsourcing platforms, like Amazon Mechanical Turk. from webly-labeled data. Each retrieved image is then examined by 3-5 annotators using Google Cloud Labeling Service who identify whether or not the web label given is correct, yielding nearly 213k annotated images. ... How can we best learn from noisy workers? of Intelligent Technology and Systems, National Lab. It is a also general framework that can incorporate state-of-the-art deep learning methods to learn robust detectors from noisy data that can also be applied to image domain. Previous works have proposed generating benign/malignant labels according to Breast Imaging, Reporting and Data System (BI‐RADS) ratings. For rare phenotypes, this may not always be true. data is used to guide the learning agent through the noisy data. Quetions arise: In summary, the contribution of this paper is threefold. However, obtaining a massive amount of well-labeled data is usually very expensive and time consuming.

Figure 1: Left: conventional gradient update with cross entropy loss may overfit to label noise. With synthetic noisy labeled data, Rolnick et al. Title: Learning to Learn from Noisy Labeled Data. There are many image data on the websites, which contain inaccurate annotations, but trainings on these datasets may make networks easier to over-fit noisy data and cause performance degradation. Abstract. Junnan Li, Yongkang Wong, Qi Zhao, Mohan S. Kankanhalli. All methods listed below are briefly explained in the paper Image Classification with Deep Learning in the Presence of Noisy Labels: A Survey. To do this, we collect images from the web using the class name (e.g., “ladybug”) as a keyword — an automatic approach to collect noisy labeled images from the web without manual annotations. (2018) develop a curriculum training scheme to learn noisy data from easy to hard. Learning classification from noisy data. Learning From Noisy Singly-labeled Data Ashish Khetan , Zachary C. Lipton , Animashree Anandkumar 15 Feb 2018 (modified: 23 Feb 2018) ICLR 2018 Conference Blind Submission Readers: Everyone In this paper, we introduce a general framework to train CNNs with only a limited number of clean labels and millions of easily obtained noisy labels. Vahdat [55] constructs an undi-rected graphical model to represent the relationship between the clean and noisy data. Approaches to learn from noisy labeled data can generally be categorized into two groups: Approaches in the first group aim to directly learn from noisy labels and focus mainly on noise-robust algorithms, e.g., [3, 15, 21], and label cleansing methods to remove or correct mislabeled data, e.g., [4]. But these labels often come from noisy crowdsourcing platforms, like Amazon Mechanical Turk. training to learn from noisy labeled data without human su-pervision or access to any clean labels.Rather than design-ing a specific model, we propose a model-agnostic training algorithm, which is applicable to any model that is trained with gradient-based learning rule. - "Learning to Learn From Noisy Labeled Data" It is more interesting to see how much meta-learning proposal improves the performance versus the true baseline.
