corruption error from 45.7 to 31.2, and reduces ImageNet-P mean flip rate from Instructions on running prediction on unlabeled data, filtering and balancing data and training using the stored predictions. In this section, we study the importance of noise and the effect of several noise methods used in our model. The main difference between our work and prior works is that we identify the importance of noise, and aggressively inject noise to make the student better. This paper proposes a pipeline, based on a teacher/student paradigm, that leverages a large collection of unlabelled images to improve the performance for a given target architecture, like ResNet-50 or ResNext. 3429-3440. . augmentation, dropout, stochastic depth to the student so that the noised Unlike previous studies in semi-supervised learning that use in-domain unlabeled data (e.g, ., CIFAR-10 images as unlabeled data for a small CIFAR-10 training set), to improve ImageNet, we must use out-of-domain unlabeled data.

Next, with the EfficientNet-L0 as the teacher, we trained a student model EfficientNet-L1, a wider model than L0. It has three main steps: train a teacher model on labeled images use the teacher to generate pseudo labels on unlabeled images We present a simple self-training method that achieves 88.4% top-1 accuracy on ImageNet, which is 2.0% better than the state-of-the-art model that requires 3.5B weakly labeled Instagram images. Although the images in the dataset have labels, we ignore the labels and treat them as unlabeled data. Chum, Label propagation for deep semi-supervised learning, D. P. Kingma, S. Mohamed, D. J.

This result is also a new state-of-the-art and 1% better than the previous best method that used an order of magnitude more weakly labeled data [ 44, 71].
Self-training with Noisy Student improves ImageNet classification We verify that this is not the case when we use 130M unlabeled images since the model does not overfit the unlabeled set from the training loss. It is found that training and scaling strategies may matter more than architectural changes, and further, that the resulting ResNets match recent state-of-the-art models. We apply RandAugment to all EfficientNet baselines, leading to more competitive baselines. For RandAugment, we apply two random operations with the magnitude set to 27.
Self-training with Noisy Student improves ImageNet classification ImageNet-A test set[25] consists of difficult images that cause significant drops in accuracy to state-of-the-art models. Algorithm1 gives an overview of self-training with Noisy Student (or Noisy Student in short). Next, a larger student model is trained on the combination of all data and achieves better performance than the teacher by itself.OUTLINE:0:00 - Intro \u0026 Overview1:05 - Semi-Supervised \u0026 Transfer Learning5:45 - Self-Training \u0026 Knowledge Distillation10:00 - Noisy Student Algorithm Overview20:20 - Noise Methods22:30 - Dataset Balancing25:20 - Results30:15 - Perturbation Robustness34:35 - Ablation Studies39:30 - Conclusion \u0026 CommentsPaper: https://arxiv.org/abs/1911.04252Code: https://github.com/google-research/noisystudentModels: https://github.com/tensorflow/tpu/tree/master/models/official/efficientnetAbstract:We present Noisy Student Training, a semi-supervised learning approach that works well even when labeled data is abundant. We use our best model Noisy Student with EfficientNet-L2 to teach student models with sizes ranging from EfficientNet-B0 to EfficientNet-B7.

If nothing happens, download Xcode and try again. When data augmentation noise is used, the student must ensure that a translated image, for example, should have the same category with a non-translated image. Self-training with Noisy Student improves ImageNet classification Abstract. Noisy Student Training achieves 88.4% top-1 accuracy on ImageNet, which is 2.0% better than the state-of-the-art model that requires 3.5B weakly labeled Instagram images. The score is normalized by AlexNets error rate so that corruptions with different difficulties lead to scores of a similar scale. First, a teacher model is trained in a supervised fashion. On ImageNet, we first train an EfficientNet model on labeled images and use it as a teacher to generate pseudo labels for 300M unlabeled images. Lastly, we will show the results of benchmarking our model on robustness datasets such as ImageNet-A, C and P and adversarial robustness. . In contrast, changing architectures or training with weakly labeled data give modest gains in accuracy from 4.7% to 16.6%. To noise the student, we use dropout[63], data augmentation[14] and stochastic depth[29] during its training. We evaluate the best model, that achieves 87.4% top-1 accuracy, on three robustness test sets: ImageNet-A, ImageNet-C and ImageNet-P. ImageNet-C and P test sets[24] include images with common corruptions and perturbations such as blurring, fogging, rotation and scaling. First, it makes the student larger than, or at least equal to, the teacher so the student can better learn from a larger dataset. Self-training with noisy student improves imagenet classification, in: Proceedings of the IEEE/CVF Conference on Computer . 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), We present a simple self-training method that achieves 88.4% top-1 accuracy on ImageNet, which is 2.0% better than the state-of-the-art model that requires 3.5B weakly labeled Instagram images. Agreement NNX16AC86A, Is ADS down? To achieve strong results on ImageNet, the student model also needs to be large, typically larger than common vision models, so that it can leverage a large number of unlabeled images. The inputs to the algorithm are both labeled and unlabeled images. Code is available at this https URL.Authors: Qizhe Xie, Minh-Thang Luong, Eduard Hovy, Quoc V.

Self-Training With Noisy Student Improves ImageNet Classification Abstract: We present a simple self-training method that achieves 88.4% top-1 accuracy on ImageNet, which is 2.0% better than the state-of-the-art model that requires 3.5B weakly labeled Instagram images. We found that self-training is a simple and effective algorithm to leverage unlabeled data at scale. unlabeled images , . (Submitted on 11 Nov 2019) We present a simple self-training method that achieves 87.4% top-1 accuracy on ImageNet, which is 1.0% better than the state-of-the-art model that requires 3.5B weakly labeled Instagram images. On . IEEE Trans. In other words, using Noisy Student makes a much larger impact to the accuracy than changing the architecture. Since a teacher models confidence on an image can be a good indicator of whether it is an out-of-domain image, we consider the high-confidence images as in-domain images and the low-confidence images as out-of-domain images. As can be seen from the figure, our model with Noisy Student makes correct predictions for images under severe corruptions and perturbations such as snow, motion blur and fog, while the model without Noisy Student suffers greatly under these conditions. Lastly, we trained another EfficientNet-L2 student by using the EfficientNet-L2 model as the teacher. This work adopts the noisy-student learning method, and adopts 3D nnUNet as the segmentation model during the experiments, since No new U-Net is the state-of-the-art medical image segmentation method and designs task-specific pipelines for different tasks. On ImageNet-P, it leads to an mean flip rate (mFR) of 17.8 if we use a resolution of 224x224 (direct comparison) and 16.1 if we use a resolution of 299x299.111For EfficientNet-L2, we use the model without finetuning with a larger test time resolution, since a larger resolution results in a discrepancy with the resolution of data and leads to degraded performance on ImageNet-C and ImageNet-P.
27.8 to 16.1. Their noise model is video specific and not relevant for image classification. possible. Noisy Student Training is based on the self-training framework and trained with 4-simple steps: Train a classifier on labeled data (teacher). The top-1 and top-5 accuracy are measured on the 200 classes that ImageNet-A includes. Noisy Student Training extends the idea of self-training and distillation with the use of equal-or-larger student models and noise added to the student during learning. We use the same architecture for the teacher and the student and do not perform iterative training. However, in the case with 130M unlabeled images, with noise function removed, the performance is still improved to 84.3% from 84.0% when compared to the supervised baseline. This work introduces two challenging datasets that reliably cause machine learning model performance to substantially degrade and curates an adversarial out-of-distribution detection dataset called IMAGENET-O, which is the first out- of-dist distribution detection dataset created for ImageNet models.
