Business Insights

1. Model choice balances accuracy, explainability & operations
In business contexts, explainable and moderately robust models sometimes beats less intuitive but more robust models.

2. Class Imbalance as a hidden risk
Highlights the importance of techniques like class weighting or threshold tuning, as models may appear accurate but fail on minority classes.

3. Payment method as a behavioral signal
Payment method can be used as a real-time trigger for personalized offers (e.g. BNPL / discounts / bundles)

4. High-lift rules reveal cross-sell opportunities
Identified associations reflect customer behavioural patterns, and indicate opportunities to target certain groups to maximisem sales

5. “Long tail” rules require strategic implementation
High-support rules → general merchandising
Medium-support, high-lift rules → targeted email/cross-sell
Low-support rules → useful if serving luxury/niche segments
