Construction Accident Prediction via Generative AI and AutoML Approaches
The construction industry faces high injury and fatality rates, making accurate accident prediction vital. While traditional machine learning (AutoML) has shown promise, its implementation often requires extensive data preprocessing and complex optimization. This study compares AutoML and Generative AI (GPT) for construction accident severity prediction, evaluating performance, training efficiency, and robustness under external validation using a dataset of 23,484 accident cases from South Korea.

AutoML Predictive Power
AutoML, exemplified by the Extra Trees Classifier, achieved 97.48% accuracy in controlled internal validation. Its strength lies in automated algorithm comparison and hyperparameter optimization, effectively leveraging structured data and ensemble learning for robust prediction when datasets are well-prepared and balanced. However, this superior performance demands significant preprocessing, including binning continuous variables, one-hot encoding, and SMOTE for class imbalance (97:3 ratio).
Generative AI Flexibility
The fine-tuned GPT-3.5-turbo-1106 model reached 75.6% accuracy in internal validation. While lower than AutoML, GPT-based models offer significant usability advantages. They require minimal data preprocessing and can directly process natural language inputs, simplifying data formatting through prompt engineering. This approach reduces the technical burden, making it more accessible for non-expert users.
Real-World Adaptability
Under external validation with newly observed, imbalanced data from 2024, AutoML experienced performance degradation, indicating sensitivity to distributional shifts and the need for continuous recalibration. In contrast, the Generative AI model maintained relatively stable performance across varying dataset scales. This robustness suggests Generative AI may be more resilient to real-world data variability, crucial for safety-critical environments.
Usability & Deployment
AutoML pipelines, while high-performing, necessitate extensive configuration and domain expertise for preprocessing, feature engineering, and interpretation. Generative AI, with its prompt-driven interaction and minimal data preparation, offers greater deployment flexibility and operational ease. It lowers barriers for practitioners lacking deep ML expertise, making advanced analytics more accessible within construction safety management workflows.

Strategic Implications for Construction Safety
The study reveals a critical trade-off: AutoML excels in peak accuracy under ideal conditions, but its real-world deployment is hampered by high data preparation demands and sensitivity to data shifts. Generative AI, while less accurate, offers superior adaptability, minimal preprocessing, and stable performance under new data conditions, making it a highly practical and user-friendly alternative for construction safety managers. This suggests a future where Generative AI could serve as a complementary, deployment-friendly tool, especially where rapid deployment and robustness against evolving operational conditions are prioritized over marginal gains in peak accuracy.
