IEEE Trans. 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. We then train a larger EfficientNet as a student model on the combination of labeled and pseudo labeled images. supervised model from 97.9% accuracy to 98.6% accuracy. Zoph et al. 3.5B weakly labeled Instagram images. For instance, on the right column, as the image of the car undergone a small rotation, the standard model changes its prediction from racing car to car wheel to fire engine. This is probably because it is harder to overfit the large unlabeled dataset. The ONCE (One millioN sCenEs) dataset for 3D object detection in the autonomous driving scenario is introduced and a benchmark is provided in which a variety of self-supervised and semi- supervised methods on the ONCE dataset are evaluated. The top-1 accuracy is simply the average top-1 accuracy for all corruptions and all severity degrees. It can be seen that masks are useful in improving classification performance. Lastly, we apply the recently proposed technique to fix train-test resolution discrepancy[71] for EfficientNet-L0, L1 and L2. Noisy Students performance improves with more unlabeled data. Figure 1(c) shows images from ImageNet-P and the corresponding predictions. We sample 1.3M images in confidence intervals. For this purpose, we use a much larger corpus of unlabeled images, where some images may not belong to any category in ImageNet. However, during the learning of the student, we inject noise such as dropout, stochastic depth and data augmentation via RandAugment to the student so that the student generalizes better than the teacher. Hence we use soft pseudo labels for our experiments unless otherwise specified. This article demonstrates the first tool based on a convolutional Unet++ encoderdecoder architecture for the semantic segmentation of in vitro angiogenesis simulation images followed by the resulting mask postprocessing for data analysis by experts. Finally, the training time of EfficientNet-L2 is around 2.72 times the training time of EfficientNet-L1. We iterate this process by putting back the student as the teacher. labels, the teacher is not noised so that the pseudo labels are as good as A new scaling method is proposed that uniformly scales all dimensions of depth/width/resolution using a simple yet highly effective compound coefficient and is demonstrated the effectiveness of this method on scaling up MobileNets and ResNet. They did not show significant improvements in terms of robustness on ImageNet-A, C and P as we did. Self-training first uses labeled data to train a good teacher model, then use the teacher model to label unlabeled data and finally use the labeled data and unlabeled data to jointly train a student model.

The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative The inputs to the algorithm are both labeled and unlabeled images. In Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition (pp. This invariance constraint reduces the degrees of freedom in the model. Their noise model is video specific and not relevant for image classification. As a comparison, our method only requires 300M unlabeled images, which is perhaps more easy to collect. possible. We use EfficientNet-B0 as both the teacher model and the student model and compare using Noisy Student with soft pseudo labels and hard pseudo labels. Noisy StudentImageNetEfficientNet-L2state-of-the-art. Since we use soft pseudo labels generated from the teacher model, when the student is trained to be exactly the same as the teacher model, the cross entropy loss on unlabeled data would be zero and the training signal would vanish. On, International journal of molecular sciences. On robustness test sets, it improves ImageNet-A top-1 accuracy from 61.0% to 83.7%, reduces ImageNet-C mean corruption error from 45.7 to 28.3, and reduces ImageNet-P mean flip rate from 27.8 to 12.2. For each class, we select at most 130K images that have the highest confidence. 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. Then we finetune the model with a larger resolution for 1.5 epochs on unaugmented labeled images. 3429-3440. . Infer labels on a much larger unlabeled dataset. As shown in Figure 3, Noisy Student leads to approximately 10% improvement in accuracy even though the model is not optimized for adversarial robustness. Lastly, we follow the idea of compound scaling[69] and scale all dimensions to obtain EfficientNet-L2. The total gain of 2.4% comes from two sources: by making the model larger (+0.5%) and by Noisy Student (+1.9%). This work proposes a novel architectural unit, which is term the Squeeze-and-Excitation (SE) block, that adaptively recalibrates channel-wise feature responses by explicitly modelling interdependencies between channels and shows that these blocks can be stacked together to form SENet architectures that generalise extremely effectively across different datasets.

Noisy Student Training is a semi-supervised learning method which achieves 88.4% top-1 accuracy on ImageNet (SOTA) and surprising gains on robustness and adversarial benchmarks. The score is normalized by AlexNets error rate so that corruptions with different difficulties lead to scores of a similar scale. Here we show an implementation of Noisy Student Training on SVHN, which boosts the performance of a A novel random matrix theory based damping learner for second order optimisers inspired by linear shrinkage estimation is developed, and it is demonstrated that the derived method works well with adaptive gradient methods such as Adam. Our experiments show that an important element for this simple method to work well at scale is that the student model should be noised during its training while the teacher should not be noised during the generation of pseudo labels. Soft pseudo labels lead to better performance for low confidence data. To achieve this result, we first train an EfficientNet model on labeled ImageNet images and use it as a teacher to generate pseudo labels on 300M unlabeled images. Computer Science - Computer Vision and Pattern Recognition. Stochastic depth is proposed, a training procedure that enables the seemingly contradictory setup to train short networks and use deep networks at test time and reduces training time substantially and improves the test error significantly on almost all data sets that were used for evaluation. However, the additional hyperparameters introduced by the ramping up schedule and the entropy minimization make them more difficult to use at scale. It 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. In contrast, the predictions of the model with Noisy Student remain quite stable. Self-Training With Noisy Student Improves ImageNet Classification.
