Regression？

[EMsnap]

May I ask how you labeled the data while training regression model? Just labeled every image with a score between 0 - 5, right? And then graded them using the score like grade 1.8 to level 2?

We labeled each image with integer score 0 - 5. During scoring process, the score of a image is not grounded back to integer. Score 1.8 just means that it is between level 1 and 2, a little bit more toward 2.
