Elbow method was never working well in practice. In my over a decade of experience I am yet to see a significant separation in the chart.

- azinman2 2y agoSo what do you do instead?
- renewiltord 2y agoKetamine but that didn’t help either.
- rgavuliak 2y agoHow does this reply make sense?
- rgavuliak 2y agoUsually I try to tie the clusters to some kind of a bottom line metric. It's not always possible though. To be honest I am not a big fan of segmentation as is, since it results in a set of subjective decisions when both deciding number of clusters and their interpretation. An alternative is DBSCAN which comes up with natural clusters, but its also not 100 % foolproof as it has a group of unclusterables which at times ends up too high.
