MobileNetV1[12]contains a total of 28 layers, among which 13 are depthwise separableconvolutional layers. For some of depthwise convolutions, the stride is set to 2 for downsampling, and the prediction results are finally output through the softmax layer. MobileNet also introduces two hyperparame...
相同的输入,同样是得到4张Feature map,Separable Convolution的参数个数是常规卷积的约1/3。因此,在参数量相同的前提下,采用Separable Convolution的神经网络层数可以做的更深。 Xception: Deep Learning with Depthwise Separable Convolutions, François Chollet ↩︎ MobileNets: Efficient Convolutional Neural Netwo...
Depthwise separable convolution (DSC) was proposed to reduce computation especially in convolutional layers by separating one convolution into a spatial convolution and a pointwise convolution. In this paper, we apply DSC to the YOLO network for object detection and propose a faster version of DSC, ...
5. We set the first two convolutional layers in DDCNNC-I to dilated convolutional layers, and set all remaining convolutional layers to depthwise separable convolutional layers. We expand the receptive field by continuously using the dilated convolutional layer. In this model, we used BBO to ...
3. The Xception architecture We propose a convolutional neural network architecture based entirely on depthwise separable convolution layers. In effect, we make the following hypothesis: that the map- ping of cross-channels correlations and spatial correlations in the feature maps of convolutional ...

Training and validation accuracy of network with depthwise separable convolutional layers The highest validation accuracy is similar for both models, but the depthwise separable convolution appears to have less overfitting to the train set, which might help it generalize better to new data. Combining al...
Compared to traditional convolutional operation the depthwise separable convolution splits this into two layers, a separate layer for filtering and a separate layer for combining. This factorization has the effect of drastically reducing computation and model size. Depthwise separable convolutions are more...
Depthwise Separable Convolution Depthwise Separable Convolution于2017年在《MobileNets: Efficient Convolutional Neural Networks for Mobile VisionApplications》提出。 标准卷积操作所使用卷积核与输入特征具有相同的通道数,卷积核个数即为输出特征的通道数。 ...卷积...
Layers of DSynthNet−Pixel are shorted with gated skip connections to the corresponding deptwise separable convolution layer with the same dimension in ESynthNet−Pixel. Three variations of gated skip connections are demonstrated in SynthNet-Pixel architecture. Those are identity gated skip ...
