进一步地,定理3.4还揭示了long skip connection上的scaling还可以影响模型对输入扰动的鲁棒上界,提升扩散模型对输入扰动的稳定性。 成为Scaling: 通过上述的分析,我们清楚了Long skip connection上进行scaling对稳定模型训练的重要性。 \kappa_i=1/\sqrt{2} 也适用于上述的分析。接下来,我们将分析怎么样的scaling可以有...
在unet中,到达中间模块,潜在空间被压缩到最小,在上采样模块中,每一次经过upsample模块,输出的潜在空间又一层层返回成原来的大小。每一层级内都存在从下采样模块到上采样模块的 skip connection,并且都是在resnetblock模块中进行这一操作。Step embedding 是在 resnetblock中加入的,目的是为了让unet知道当前进行到了...
Furthermore, we introduce Skip-NAT (Neighborhood Attention Transformer) as the main algorithmic framework, replacing U-Net's original skip-connection layers, to lessen the impact of shallow features on network efficiency. Experimental results show that CAT-Unet achieves better segmentation results. On ...
with Unet: (1) modifying the interconnection of the network node, (2) using dilated convolution instead of the standard convolution, and (3) integrating the multi-scale input features on the input side of the model and applying a dense skip connection instead of a regular skip connection. Our...
Those issues are circumvented by integrating U‐Net and the swin transformer together, with an efficiently designed dual attention mechanism based skip connection. Typically, a swin transformer based encoder‐decoder network, by incorporating a dual attentional skip connection with Swin‐UNet (DASUNet)...
如skip connection分析部分所述,作者观察到编码器的特征与解码器的特征不一致,即在某些情况下,由于浅层编码器与解码器之间存在语义差异,语义信息较少的浅层特征可能会通过简单的skip connection损害最终性能。受此启发,作者通过在普通U-Net编码器和解码器之间设计一个通道化的Transformer模块来构建UCTransNet框架,以更好...

Inspired by the swin transformer [10] which mines the self-attention based on the shifted window partition, we propose to design a dual attentional skip connection in Swin-UNet (DASUNet) for cloud segmentation. DASUNet utilizes the advantages of U-shaped architecture and swin transformer from two...

【新智元导读】本文提出了扩散模型中UNet的long skip connection的scaling操作可以有助于模型稳定训练的分析,目前已被NeurIPS 2023录用。同时,该分析还可以解释扩散模型中常用但未知原理的1/√2 scaling操作能加速训练的现象。 在标准的UNet结构中,long skip connection上的scaling系数 ...
