文中还介绍了 ImageNet-22K 的 intermediate fine-tuning(中间微调)结果:intermediate fine-tuning 的训练过程包括三个步骤:1. FCMAE 预训练;2. ImageNet-22K 微调;3. ImageNet1K 微调。结果如下表所示: Table 5. ImageNet-1K fine-tuning results using IN-21K labels. The ConvNeXt V2 Huge model equipped...
译者注:columns的解释我查阅了一篇名为Multi-column Deep Neural Networks for Image Classification的论文,也是Ciresan写的,里面有提到一个column就是一个DNNmodel,在此文中我推测是指单个GPU里的神经网络。而非独立就是指两个GPU上的网络之间是有连接层的。在文中引用的“柱状”CNN from reference[5]High-Perform...

and the resulting receptive field is only a sparse sampling of input image with checkerboard patterns. In this paper, we present a novel multi-level wavelet CNN (MWCNN) model for better tradeoff between receptive field size and computational efficiency. With the modified U-Net architecture, wavele...
