Standardized and documented the evaluation process for uplift models, establishing a cost evaluation framework for targeting models that addresses ambiguities due to slight variations in existing literature.
Developed an enhanced uplift model with less noisy labels for soft churn earners, significantly improving targeting policy performance for the courier cohort. Successfully deployed the model into production and designed an experiment (XP) to validate the model’s enhancement.
Designed and implemented a new targeting model that incorporates cost considerations, achieving both cost savings and incrementality improvements.
