MOSIC: Model-Agnostic Optimal Subgroup Identification with Multi-Constraint for Improved Reliability
arXiv:2504.20908v3 Announce Type: replace Abstract: Current subgroup identification methods typically follow a two-step approach: first estimate conditional average treatment effects and then apply thresholding or rule-based procedures to define subgroups. While intuitive, this decoupled approach fails to incorporate key constraints essential for real-world clinical decision-making, such as subgroup size and propensity overlap. These constraints operate on fundamentally different axes than CATE estimation and are not naturally accommodated within existing frameworks, thereby limiting the pract
The increasing deployment of AI in high-stakes domains necessitates more robust and reliable subgroup identification methods to ensure practical and ethical application.
This development improves the reliability and practicality of AI in critical applications like clinical decision-making by integrating real-world constraints directly into model design.
AI models for subgroup identification can now inherently consider practical constraints, moving beyond purely statistical optimization to deliver more actionable and trustworthy results.
