The paper "A ConvNet for the 2020s" by Zhuang Liu, Hanzi Mao, Chao-Yuan Wu, Christoph Feichtenhofer, Trevor Darrell, and Saining Xie explores the potential of Convolutional Neural Networks (ConvNets) in the context of Vision Transformers (ViTs). While ViTs have dominated image classification tasks, they struggle with general computer vision tasks like object detection and semantic segmentation. The authors investigate how to modernize a standard ResNet to achieve similar performance to hierarchical vision Transformers, such as Swin Transformers, without introducing attention-based modules. They discover several key components that contribute to the performance difference and propose a family of pure ConvNet models called ConvNeXt. ConvNeXts are evaluated on various vision tasks, including ImageNet classification, COCO object detection, and ADE20K semantic segmentation, achieving competitive or superior performance to Swin Transformers while maintaining the simplicity and efficiency of standard ConvNets. The study challenges the notion that Transformers are intrinsically superior and highlights the importance of convolutions in computer vision.The paper "A ConvNet for the 2020s" by Zhuang Liu, Hanzi Mao, Chao-Yuan Wu, Christoph Feichtenhofer, Trevor Darrell, and Saining Xie explores the potential of Convolutional Neural Networks (ConvNets) in the context of Vision Transformers (ViTs).
