I'm looking for the best way to check if our customers have the correct segmentation label.
(New) customers are given a segment label at creation, mainly based on the information available at that time. There is a fixed list of segments.
We would like to check if there are customers for whom the segment might not be correct, based on their buying behavior and other parameters. We can't really use clustering (unsupervised), since we already have a fixed list of segments (which will not change). Anyone have an idea on how we should approach this question?
