Question 14: SRGAN and ESRGAN are both deep learning architectures de…

Select all that apply.

1. A

   ESRGAN replaces the standard residual blocks in SRGAN with Residual-in- Residual Dense Blocks (RRDB) for better performance.

2. B

   SRGAN employs Perceptual Loss, while ESRGAN removes it to focus only on pixel-wise MSE loss for training stability.

3. C

   ESRGAN produces sharper and more realistic textures than SRGAN due to architectural and loss function improvements.

4. D

   Both SRGAN and ESRGAN use a VGG-based perceptual loss computed on feature maps extracted from deeper and shallower layers, respectively, of a pretrained classifier.

5. E

   SRGAN is trained using only adversarial and perceptual losses, whereas ESRGAN includes a content loss computed using pixel-wise L1 loss.
