一, Keras SeparableConv2D,分两步完成卷积: Depthwise Conv 和 Pointwise Conv。 Depthwise Conv对每个通道进行卷积,Pointwise Conv为1*1的卷积核,深度根据需求定义。Keras SeparableConv2D较正常的卷积,可以大大节省参数。 二,DepthwiseConv2D相当于 SeparableConv2D的第一... ...

Correct, checking the source code (I did this for tf.keras but I suppose it is the same for standalone keras) shows that in SeparableConv2D, the separable convolution works using only filters, no biases, and a single bias vector is added at the end. The second version, on the other ...
