I would like to have some suggestions on possible avenues that would make sense in the following context.
- 3 Optimal clusters have been identified in a 5000 list of customers using Kmeans
- Data model has 30 features and a PCA was performed prior to Kmeans.
I would like to further breakdown each of these 3 clusters into smaller tiers for each cluster. These tiers would server in ranking each customer within his cluster.
For example: Cluster 1, 2, 3 could all have 4 or 5 tiers.
What interesting option could I explore to create the tiers within the 3 clusters (e.g. RFM quantile separation, classification algorithms)?
