PILOT: Physics-Informed Optimized LightGBM for Edge-Based Predictive Maintenance

Öz

In Industry 4.0 applications, predictive maintenance is one of the frequently used methods for optimizing equipment reliability and maintenance costs. This paper proposes a new framework for edge-based machine fault detection, Physics-Informed Optimized LightGBM for Edge-Based Predictive Maintenance (PILOT), using a public dataset, AI4I 2020. The approach derives physics-informed interaction features from sensor data and uses Optuna to optimize the LightGBM hyperparameters. To ensure a fair comparison, the proposed model is compared with a known reference study from the literature. Experimental results show that the proposed approach provides a relative improvement of 0.51% in accuracy, 7.52% in precision, 11.12% in recall, and 9.40% in F1 score compared to the basic LightGBM model. To test the suitability of deployment for edge environments, the compared models were deployed on a Raspberry Pi 4 device. The results confirm the suitability of the proposed model for edge environments with a 5ms prediction time, even though it requires additional training and prediction time compared to other models.
