Now we know how to use transpose convolution to up-samples an image. When you are training a neural network we need to figure out the values in filters of transpose convolution layers, same as in CNN. That’s where our friend backpropagation comes to help.Thanks...

To achieve this, especially after the spatial dimensions are reduced by CNN layers, we can use another type of CNN layers that can increase (upsample) the spatial dimensions of intermediate feature maps. In this section, we will introduce transposed convolution, which is also called fractionally-...

I was testing for the node 576, which is a final convolution output and the results really differ. Using the polygraphy I just tested the input/outputs of the 3 ConvTranspose2d layers the model has. While nodes 546 and 560 were pretty much close, the output of the 3rd block node 574 ...
