Hi, i want to ask this question. I have segmentation performance of DB Index in negative values. why is it negative? How is the calculation of DB Index?. and which one is better -0.8 or -1.3 ? Thankyou

hi @rinitairi,

by convention those measures need to be maximized. In order that this is true, we multiplied it by -1. So -0.8 is better than -1.3

Best,
Martin
