> Should I normalize or scaling the target？

Hello, guys! I'm a novice in image quality assement. I found that the MOS in training set are very large, should i normalize the label or scaling it into [0, 1] to train my CNN model? If i tansform the target, how can i transform the predictions back to real MOS value to create the submission file? Need your help, thanks.

Hi,

In theory, you don't need to scale your results. Scaling does not change the results of SRCC. And before calculating the PLCC, the scoring program will fit your results.

Thanks,
