Implementation of delated convolution

I am interested in time of inference of delated convolution. Is it the same time like usual convolution?
I know that Flops depend on output size, kernel size and amount of in-/out- channels.
I can’t find an implementation of delated convolution. Does kernel size change in delated convolution?

I did a test. It turned out that usual convolution faster, then delated. Why does it happen?


@ptrblck_de, please, answer the question)

The flops will be nominally the same, but

  • The memory accesses will be less “compact”,
  • they are less often used and likely less well-tuned - convolutions are among the crazily well-tuned and computationally very demanding functions.

Best regards


Thank you, Thomas.

Is there something better then dilated convolution, if I want to have a big receptive field?
I want to replace dilated convolution, because to count it longer then usual convolution.

The most standard way is pooling, probably. I’m not sure there are many much better ways.

Best regards


Thank you very much, Thomas
