Now, the authors argue that using the second option is better because it helps the model learn how to adjust the representations better with respect to the given resolution. Since the results purely are empirical, a few more experiments such as analyzing the cross-channel interaction would have been even better. It is worth noting that elements like Squeeze and Excitation (SE) blocks, Global Context (GC) blocks also add a few parameters to an existing network but they are known to help a network process information in systematic ways to improve the overall performance.
