如果把常规convolution的计算过程理解成正卷积,那么conv_transpose就可以称做“反卷积”,一些框架索性把这个操作叫做deconvolution(caffe, MNN),还有一些“正统框架”叫做conv_transpose(TensorFlow, PyTorch, PaddlePaddle), 笔者认为这两个名字所描述的操作是等价的。 conv_transpose有啥用?conv_transpose还是蛮有用的,...
Depthwise Convolution 对每个输入通道独立进行卷积,可以看做是特殊的组卷积(输出的通道数=输出的通道数=G) 就是分组卷积在通道方面连接最稀疏的特例,M=N=G,计算量为 K*K*N*H*W*M/G = K*K*H*W*M,是标准3 x 3卷积的1/N channel shuffle ShuffleNet中用的,改变通道的顺序,通过对tensor进行reshape和tra...
First I chose transpose convolution(De-Conv) at this position. But in the output image I observe huge checker-board issues. Thats why I choose pixel shuffling at this stage. Pixel shuffling algorithm is famous to avoid checker-board issues. ...
Base class for performing an `n`-dimensional convolution on its input, optionally adding a bias and applying an elementwise nonlinearity. Note that this class cannot be used in a Lasagne network, only its subclasses can (e.g., :class:`Conv1DLayer`, :class:`Conv2DLayer`). Parameters ---...

The third decoder architecture employed consists of a sequence of deconvolution (transpose convolution) layers plus convolutional layers both with Relu activations. The deconvolution layers are configured as 2×22×2 kernels with a stride of 2 to double the size of the input and the convolutional ...
As shown inTable 2, thanks to temporal information, Pavllo’s [10] model reduces the error by about 5 mm on average compared to its single-frame baseline model (where the width of all convolution kernels was set to W = 1). The gap between them is more significant on some more dynamic...
,1 respectively, ConcatConcat is the concatenation function concatenating the feature maps dimensionally, rather than the point-wise sum. FF comprises the operations, including convolution, pooling and nonlinear transformations with the weight 𝐖𝑙Wl. It shows that continuous concatenation of different...
