bg 为水印位置目标图,m 为预测覆盖图 对于第二阶段预测最终目标图,作者采用了 S2AM (Cun and Pun 2020): Spatial-Separated Attention Module 模块,为了能够更好学习低层特征,作者将模块的前八层改为 SplitNet 中提出的五层模块,具体结构如图: 可以参考代码: classVMSingleS2AM(nn.Module):def__init__(self,...

第一个贡献点:提出了split-attention blocks构造的ResNeSt,与现有的ResNet变体相比,不需要增加额外的计算量。而且ResNeSt可以作为其它任务的骨架。 第二个贡献点:图像分类和迁移学习应用的大规模基准。 利用ResNeSt主干的模型能够在几个任务上达到最先进的性能,即:图像分类,对象检测,实例分割和语义分割。 与通过神经架构...

ResNet-D的技巧:替换7x7卷积为3x3;shortcut stride=2时在1x1 conv前加avg pool避免信息丢失 Label Smoothing、MixUp、DropBlock等 四、评价 本文属于将Attention机制用在CNN上的又一大尝试,在SENet和SKNet基础上将attention进一步推广到group(cardinality)维度。

I suspect the problem comes from this mapping which splits the attention block. So indeed, we should add CrossAttnUpBlock2D inside _no_split_modules. Another way would be to make that that hidden_states, res_hidden_states are on the same device but I prefer not to add anything in the ...
