Evaluating the Use of Synthetic Data for ML Prediction in Concrete
This research explores the application of synthetic data to enhance machine learning model performance in predicting the self-healing capacity of bacteria-driven concrete. Facing limited experimental data, the study generated a synthetic dataset to train various ML models. Ensemble methods, particularly Random Forest, demonstrated superior predictive accuracy (0.863 F1-score) compared to probabilistic models. The models maintained high accuracy on real-world data, highlighting synthetic data's value in civil engineering for overcoming data scarcity and improving model reliability. Key influencing factors like water-to-cement ratio and calcium lactate concentration were identified.

Synthetic data proved crucial for developing robust models in a data-scarce domain.
Overcoming Data Scarcity in Civil Engineering
The study demonstrates that synthetic data generation is a powerful tool to address the critical challenge of limited experimental data in civil engineering, particularly for novel materials like self-healing concrete. By expanding the dataset from 38 to 350 instances, the robustness and reliability of ML models were significantly enhanced, allowing for the development of predictive tools that would otherwise be impossible with real data alone. This approach not only facilitated the identification of key influencing factors like water-to-cement ratio and calcium lactate but also provided a validated methodology for future AI applications in data-constrained domains.
