6 years ago That's a good question. Actually it is crucial to have a decent number of channels to achieve performance. What I suggest you to do is to keep the first layer at least 16 and then try to vary the number of channels in the other layers systematically and perform the experiments to see which combination works best for you.
Number of channels (kernels) is a hyper parameter of the network and it needs to be set by experimenting in cross-validation (or to be picked reasonably without going through a rigorous testing).

Hi,
How can I cut the channel size of each level to half and preserve the performance of network? what I meant is turning 16, 32, 64, 128 and 256 (in deepest layer) to 8, 16, 32, 64 and 128.
