1. Will the use of extra data affect the final ranking?
2. If we can use extra data to train the model, does the final ranking only depends on PSNR?
Sorry for the delayed response.
1. No, using extra data would not affect the rankings as long as the validation data is not used for training.
2. We will consider both PSNR and SSIM as primary criteria. We may use other metrics for further analysis.
