High-Performance Large-Scale Image Recognition Without Normalization	Batch normalization is a key component of most image classification models, but it has many undesirable properties stemming from its dependence on the batch size and interactions between examples. Although recent work has succeeded in training deep ResNets without normalization layers, these models do not match the test accuracies of the best batch-normalized networks, and are often unstable for large learning rates or strong data augmentations. In this work, we develop an adaptive gradient clipping technique which overcomes these instabilities, and design a significantly improved class of Normalizer-Free ResNets. Our smaller models match the test accuracy of an EfficientNet-B7 on ImageNet while being up to 8.7x faster to train, and our largest models attain a new state-of-the-art top-1 accuracy of 86.5%. In addition, Normalizer-Free models attain significantly better performance than their batch-normalized counterparts when fine-tuning on ImageNet after large-scale pre-training on a dataset of 300 million labeled images, with our best models obtaining an accuracy of 89.2%.	inproceedings	Proceedings of Machine Learning Research	PMLR	2640-3498	brock21a	0	High-Performance Large-Scale Image Recognition Without Normalization	1059	1071	1059-1071	1059	false	Brock, Andy and De, Soham and Smith, Samuel L and Simonyan, Karen	given family Andy Brock given family Soham De given family Samuel L Smith given family Karen Simonyan	2021-07-01		Proceedings of the 38th International Conference on Machine Learning	139	inproceedings	date-parts 2021 7 1	http://proceedings.mlr.press/v139/brock21a/brock21a.pdf
