The issue about excitation mechanism.

[TitaniumOne]

Thank you for your great work! I have an issue:
The gating mechanism proposed in the paper is :

but this mechanism of gating signal implemented in the code dose not multiply by 2.
So I want to know is this operation important or do I miss some details?

Hi,

Thanks for pointing that out! It seems we have missed the multiplication in the re-implementation but I don't believe it would make a big difference in the final results.

Thanks for your kindly reply!
I think 3D models for RGB input are computationally intensive (because I have few GPUs, hahaha), so I wonder if it is possible to fuse 2D models for RGB input (such as TSN) and skeleton based models (such as 2SA-GCN) by MMTM module. Have you considered it?
