Machine Learning Predictive Modeling Pipeline
- Problem
- A 95/5 class imbalance meant a model could score 95% accuracy and still miss every stroke.
- Tools
- Pythonpandasscikit-learnGridSearchCVK-MeansPCA
- Result
- Stroke recall raised from 0% to 80% (AUC 0.84); four customer segments identified.
