A hybrid CNN-Transformer model, TransformerSHM, enables highly accurate structural health monitoring of semiconductor probe cards, classifying health states with 99.83% accuracy and 99.86% balanced accuracy. The model leverages attention mechanisms to identify optimal sensor placements, providing data-driven guidance for efficient sensor network design.

Key insights

• Hybrid CNN-Transformer architectures effectively combine local feature extraction with global contextual understanding to accurately diagnose complex mechanical failures in intricate components.
• Transformer attention mechanisms provide interpretable insights into sensor importance, enabling data-driven identification of optimal sensor locations for efficient and cost-effective monitoring systems.
• Physics-informed data generation and augmentation, coupled with rigorous cross-validation, are crucial for developing robust and generalizable deep learning models for SHM applications with limited real-world data.
