On the uncertain label problem

[Shirugo]

Dear Author:
Hello, first of all, thank you for sharing the great project! During my study, I encountered some problems, and I would like to ask you: The first question is that the labels of training and verification sets in ChexPert data set are all 14 categories, so I want to extend the five categories in your code to 14 categories. I noticed that official website only evaluated five categories for data sets, and gave five methods for uncertain labels. So why did you use U-one and U-zero in your code? The second question is, do you have any better suggestions for the selection of uncertain labels in other nine diseases?
I look forward to your reply! Wish you a happy life!
