What does the confidence_score actually represent in the Perception CNN? #11802

In the CNN in the perception module, there exists a category_score and confidence_score. The category_score is used with the objectness_thresh to determine if something is an object and the confidence_score is used with the confidence_thresh.

However, I am confused as to what the confidence_score means. In the documentation 3d_obstacle_perception.md, it seems to align with 'positiveness' but I don't know what that is.

Is this question still being looked at? Or is there a research paper/doc I can consult to get this answer?

Also I don't know why commenting unassigned people.
