Hint for classification

Wow, the stage 2 is super hard even through the host think it is too easy :slight_smile:

I am just trying to do a classification to separate the targets into a positive group and a negative group. Still haven’t understood how to do that.

It would be great if any of you could give a hint !!!

@team @tien2020.le2020 For whatever VERY strange reasons, stage-2 was made impossible to pass. I passed it with a lot of guessing. Note: given parameters do not match backend solutions.
