WebA 1x1 convolution is actually a vector of size f 1 which convolves across the whole image, creating one m x n output filter. If you have f 2 1x1 convolutions, then the output of all of the 1x1 convolutions is size ( m, n, f 2). So a 1x1 convolution, assuming f 2 < f 1, can be seen as rerepresenting f 1 filters via f 2 filters.

WebNov 14, 2024 · The model I created is reconstructing the images just by its architecture. As you can see I’ve created a “bottleneck” in the model, i.e. the activations will get smaller, and after it I used transposed conv layers to increase the spatial size again. The last layer outputs the same shape as the input had. WebJul 5, 2024 · The 3 is the number of input channels (R, G, B).That 64 is the number of channels (i.e. feature maps) in the output of the first convolution operation.So, the first conv layer takes a color (RGB) image as input, applies 11x11 kernel with a stride 4, and outputs 64 feature maps..
