[Question] Difference between ConvolutionTranspose and GenerativeConvolutionTranspose #463

Open Wayne2Wang opened 2 years ago

Wayne2Wang commented 2 years ago

Hi, thank you for sharing this super cool library.

I just have a quick question about these two functions. It seems to me that ConvolutionTranspose with expand_coordinates=True is the same as GenerativeConvolutionTranspose. I've gone through 

@inproceedings{gwak2020gsdn,

author={Gwak, JunYoung and Choy, Christopher B and Savarese, Silvio},  
booktitle={European conference on computer vision},  
year={2020}

Can someone correct me or confirm this please?

Thanks
