About the loss #13
Comments
l_d_fake and l_d_real are losses for the discriminator. d means discriminator and g means generator. |
real is GT , fake is Y_predict? |
Yes. |
I used your dataset to train on train_EDVR-GAN_woTSA_RealVSR_YCbCr_Split, and found that psnr_avg has been gradually decreasing, and finally dropped to 25.44. Shouldn't psnr be on the rise? |
If you use GAN in training, the psnr will decrease. |
Could u tell me why? |
GAN training is usually for visual quality but not for objective measures like psnr and ssim. |
if 'g' is generator,what is l_g_gan? Doesn't gan mean GAN? |
Yes it is the GAN loss for generator. |
I want to know what l_d_fake and l_d_real mean, l_g_gan is the sum of discriminator and generator? And what the 'd' and 'g' in l_d_fake and l_g_pix_s stand for?
