Leakage-Controlled and Applicability-Domain-Aware Machine Learning Optimization of Fly Ash-GGBS Geopolymer Concrete

The results demonstrate that high apparent predictive accuracy is insufficient for responsible data-driven geopolymer mixture design; optimization outputs should be filtered through leakage-aware validation, regional reliability diagnosis, explainable feature attribution, and applicability-domain screening before being...
