Performing Unsupervised Learning on a Credit Card Data to Segment Customers into different clusters using KMeans Clustering.
- CC GENERAL.csv
This case requires trainees to develop a customer segmentation to define marketing strategy. The sample dataset summarizes the usage behavior of about 9000 active credit card holders during the last 6 months. The file is at a customer level with 18 behavioral variables.
- Advanced data preparation: Build an ‘enriched’ customer profile by deriving “intelligent” KPIs such as:
- Monthly average purchase and cash advance amount
- Purchases by type (one-off, installments)
- Average amount per purchase and cash advance transaction,
- Limit usage (balance to credit limit ratio),
- Payments to minimum payments ratio etc.
- Advanced reporting: Use the derived KPIs to gain insight on the customer profiles.
- Identification of the relationships/ affinities between services.
- Clustering: Apply a data reduction technique factor analysis for variable reduction technique and a clustering algorithm to reveal the behavioural segments of credit card holders
- Identify cluster characterisitics of the cluster using detailed profiling.
- Provide the strategic insights and implementation of strategies for given set of cluster characteristics
