Hi @albanD, thanks for your explanation about the definition of _convolution_double_backward(). When reading this code, I was confused about the parameter like ggI
, ggW_r
, ggb
and gO_r
and output_mask
and the target of calculating ggW
, gI
and gW
.
Under my superficial understanding of all these, ggW_r
means the gradient of convolution kernel? xx_r
means a requirement, ggb
is the gradient of bias.
Really hope your advice on how to realize these parameters and the calculation of ggW
, gI
and gW
.
Thank you very much!
