Should we normalize the target value in K-nearest neighbour?

I’ve googled this question, and some people say it’s not necessary, some say it is. So what’s the right answer? :slight_smile:

Could you share links to your research, that way answerers can avoid repeating what you already know, while learning something for themselves.

I have never seen people discuss target value in KNN. Usually what i see is normalizing the features or not.
My impression is target values do not need normalization since they are not part of the KNN algorithm inputs (non-target columns) to finding which are the K neighbors.
