A recent analysis questions the fundamental hypothesis behind Efficient Channel Attention (ECA), a 2019 paper with over 12,000 citations. The author argues that ECA's core mechanism, which applies a 1D convolution directly to channel means, is conceptually flawed because it treats channel dimensions as having a topology, which is inappropriate for tabular data. While ECA demonstrated improvements over its predecessor, Squeeze-and-Excitation (SE), the author's experiments using chess endgame tablebases suggest that ECA's design is inefficient for such data, even though neural networks can adapt to it.
