Whether the model benefits from more unlabeled data depends on the capacity of the model since a small model can easily saturate, while a larger model can benefit from more data. 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. For this purpose, we use a much larger corpus of unlabeled images, where some images may not belong to any category in ImageNet. 2023.3.1_2 - Overall, EfficientNets with Noisy Student provide a much better tradeoff between model size and accuracy when compared with prior works. Here we show the evidence in Table 6, noise such as stochastic depth, dropout and data augmentation plays an important role in enabling the student model to perform better than the teacher. We then train a student model which minimizes the combined cross entropy loss on both labeled images and unlabeled images. We use the standard augmentation instead of RandAugment in this experiment. To intuitively understand the significant improvements on the three robustness benchmarks, we show several images in Figure2 where the predictions of the standard model are incorrect and the predictions of the Noisy Student model are correct. 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.

Self-Training with Noisy Student Improves ImageNet Classification Models are available at this https URL. Self-training with Noisy Student - [68, 24, 55, 22]. 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. [50] used knowledge distillation on unlabeled data to teach a small student model for speech recognition. Our study shows that using unlabeled data improves accuracy and general robustness. 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. We apply RandAugment to all EfficientNet baselines, leading to more competitive baselines. Are you sure you want to create this branch? et al. But during the learning of the student, we inject noise such as data It has three main steps: train a teacher model on labeled images use the teacher to generate pseudo labels on 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. But training robust supervised learning models is requires this step. For RandAugment, we apply two random operations with the magnitude set to 27. possible. We duplicate images in classes where there are not enough images. First, a teacher model is trained in a supervised fashion. arXiv:1911.04252v4 [cs.LG] 19 Jun 2020 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. Also related to our work is Data Distillation[52], which ensembled predictions for an image with different transformations to teach a student network. During the generation of the pseudo At the top-left image, the model without Noisy Student ignores the sea lions and mistakenly recognizes a buoy as a lighthouse, while the model with Noisy Student can recognize the sea lions. https://arxiv.org/abs/1911.04252. For each class, we select at most 130K images that have the highest confidence. We train our model using the self-training framework[59] which has three main steps: 1) train a teacher model on labeled images, 2) use the teacher to generate pseudo labels on unlabeled images, and 3) train a student model on the combination of labeled images and pseudo labeled images. Addressing the lack of robustness has become an important research direction in machine learning and computer vision in recent years. 27.8 to 16.1. 10687-10698). We present Noisy Student Training, a semi-supervised learning approach that works well even when labeled data is abundant. 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. The swing in the picture is barely recognizable by human while the Noisy Student model still makes the correct prediction. Specifically, we train the student model for 350 epochs for models larger than EfficientNet-B4, including EfficientNet-L0, L1 and L2 and train the student model for 700 epochs for smaller models. The paradigm of pre-training on large supervised datasets and fine-tuning the weights on the target task is revisited, and a simple recipe that is called Big Transfer (BiT) is created, which achieves strong performance on over 20 datasets. We start with the 130M unlabeled images and gradually reduce the number of images. We then train a larger EfficientNet as a student model on the combination of labeled and pseudo labeled images. ImageNet . It can be seen that masks are useful in improving classification performance. Do imagenet classifiers generalize to imagenet? Finally, in the above, we say that the pseudo labels can be soft or hard. E. Arazo, D. Ortego, P. Albert, N. E. OConnor, and K.

Noisy Student can still improve the accuracy to 1.6%. 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. Conclusion, Abstract , ImageNet , web-scale extra labeled images weakly labeled Instagram images weakly-supervised learning . Self-Training With Noisy Student Improves ImageNet Classification on ImageNet ReaL For instance, on ImageNet-A, Noisy Student achieves 74.2% top-1 accuracy which is approximately 57% more accurate than the previous state-of-the-art model. This is a recurring payment that will happen monthly, If you exceed more than 500 images, they will be charged at a rate of $5 per 500 images. In Noisy Student, we combine these two steps into one because it simplifies the algorithm and leads to better performance in our preliminary experiments. We used the version from [47], which filtered the validation set of ImageNet. sign in 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]. As stated earlier, we hypothesize that noising the student is needed so that it does not merely learn the teachers knowledge. In this work, we showed that it is possible to use unlabeled images to significantly advance both accuracy and robustness of state-of-the-art ImageNet models. Selected images from robustness benchmarks ImageNet-A, C and P. Test images from ImageNet-C underwent artificial transformations (also known as common corruptions) that cannot be found on the ImageNet training set. Agreement NNX16AC86A, Is ADS down? Our largest model, EfficientNet-L2, needs to be trained for 3.5 days on a Cloud TPU v3 Pod, which has 2048 cores.

Models are available at https://github.com/tensorflow/tpu/tree/master/models/official/efficientnet. Self-training Although the images in the dataset have labels, we ignore the labels and treat them as unlabeled data. and surprising gains on robustness and adversarial benchmarks. 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. Self-training with Noisy Student improves ImageNet classification Specifically, as all classes in ImageNet have a similar number of labeled images, we also need to balance the number of unlabeled images for each class.

Self-Training With Noisy Student Improves ImageNet Classification IEEE Transactions on Pattern Analysis and Machine Intelligence. Lastly, we follow the idea of compound scaling[69] and scale all dimensions to obtain EfficientNet-L2. 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. Infer labels on a much larger 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. unlabeled images , . Are you sure you want to create this branch? There was a problem preparing your codespace, please try again. In addition to improving state-of-the-art results, we conduct additional experiments to verify if Noisy Student can benefit other EfficienetNet models. Lastly, we trained another EfficientNet-L2 student by using the EfficientNet-L2 model as the teacher. Although they have produced promising results, in our preliminary experiments, consistency regularization works less well on ImageNet because consistency regularization in the early phase of ImageNet training regularizes the model towards high entropy predictions, and prevents it from achieving good accuracy. 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].
