Using Depthwise Separable Convolutions in Tensorflow

WebYour Example. In your example we have 3 input and 2 output units. To apply convolutions, think of those units having shape: [1,1,3] and [1,1,2], respectively.In CNN terms, we have 3 input and 2 output feature maps, each having spatial dimensions 1 x 1.. Applying an n x n convolution to a layer with k feature maps, requires you to have a kernel of shape [n,n,k]. Web23 jun. 2024 · 즉 1 X 1 X 3 커널을 8 X 8 X 3 이미지에 반복시켜 8 X 8 X 1 이미지를 얻는다.
