I've extracted the weights from the filters of a pretrained model (AlexNet). I wish to represent these weights visually, this works fine for the first layer as there is only 3 input channels so I can represent the filters as color images with channels (RGB).

However this breaks down in later layers as they often have more than 3 input channels, I can represent them as many greyscale kernels but was hoping someone has found a better solution.

  • $\begingroup$ Seldom does it help due to the fact that they are small. You cannot find many meaningfull patterns that can help you. For instance, a $5\times5$ filter is very small. The papers usually visualise the outputs of a convolution. $\endgroup$ – Media Mar 21 at 21:03

  • $\begingroup$ The outputs of convolutional layers are called activation maps or feature maps. $\endgroup$ – Media Mar 22 at 9:21
