May I ask how much improvement the LCE used in the article has brought?

rayleizhu commented 1 year ago

The short answer is, I do not know. I did not do this ablation experiment after the architecture is finalized.

LCE is added to our architecture during our early exploration period. If I remember correctly, At that time, we used DWConv in stages 1 & 2, BRA in stages 3 & 4, the improvement brought by LCE is 0.2 or so. I guess it plays the role of position encoding.

Thanks.
