在特征可视化、训练阶段的反向传播中应用的transposed convolution,并不是作为一个真正的layer存在于网络中,其kernel与convolution共享(但要经过中心对称后再卷积,相当于上面的CT。 在图像分割、生成模型、decoder中使用的transposed convolution,是网络中真实的layer,其kernel经初始化后需要通过学习获得(所以卷积核也就无所谓...
上采样和反卷积 Up-sampling and Transposed Convolution (Deconvolution),程序员大本营,技术文章内容聚合第一站。
:TransposedConvolution,Fractional StridedConvolution等等。这篇文章的目的主要有两方面: 1. 解释卷积层和反卷积层之间的关系;2. 弄清楚反卷积层输入...Convolution上面也提到过反卷积有时候也被叫做Fractionally StridedConvolution,翻译过来大概意思就是小数步长的卷积。对于步长 s>1s>1参考...

在图像分割、生成模型、decoder中使用的transposed convolution,是网络中真实的layer,其kernel经初始化后需要通过学习获得(所以卷积核也就无所谓中心对称不对称了)。 前向传播为convolution/transposed convolution,则反向传播为transposed convolution/convolution。
因此,结合上面所得到的结论,我们可以得出Fractionally Strided Convolution的输入输出关系为: o′=s(i′−1)+k−2po′=s(i′−1)+k−2p 参考 conv_arithmetic Is the deconvolution layer the same as a convolutional layer?
So far, the transposed convolution layer does not support bias terms. The following generic parameters GenParamName and the corresponding values GenParamValue are supported: 'bias_term': Determines, whether the layer has bias terms. As mentioned above, bias terms are not supported yet, so this ...
