About this paper

Yuandi Wu, Brett Sicard, Stephen Andrew Gadsden

A comprehensive review by researchers at McMaster University categorizes and analyzes physics-informed machine learning (PIML) methodologies for condition monitoring (CM) and anomaly detection (AD) into four primary integration frameworks. The work details the underlying principles, advantages, and limitations of each method, identifying their prevalence in existing literature.

Key insights

• Physics-Informed Machine Learning (PIML) provides a hybrid paradigm that mitigates the data dependency and "black box" nature of pure ML, while enhancing the accuracy and robustness of traditional physics-based models.
• The diverse methodologies for integrating physics into ML models offer varying trade-offs in computational efficiency, model interpretability, and generalizability, depending on how deeply physics is incorporated.
• A clear trend indicates a shift from physics-guided feature augmentation towards more deeply embedded physical constraints via regularization and architectural design for enhanced physical consistency and data efficiency.
