New B-PINN framework enhances uncertainty quantification for material degradation prognostics

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new Bayesian Physics-Informed Neural Network (B-PINN) framework designed to improve uncertainty quantification in prognostics and health management (PHM). This novel approach jointly models both epistemic and aleatoric uncertainty, offering more comprehensive predictive posteriors for applications like estimating insulation material ageing. The framework was evaluated on transformer insulation ageing, validated with thermal models and field measurements, and demonstrated superior accuracy and calibration compared to existing deterministic and Bayesian PINN variants.

    Disentangling Aleatoric and Epistemic Uncertainty in Physics-Informed Neural Networks. Application to Insulation Material Degradation Prognostics

    arXiv:2601.03673v2 Announce Type: replace-cross Abstract: Physics-Informed Neural Networks (PINNs) provide a framework for integrating physical laws with data. However, their application to Prognostics and Health Management (PHM) remains constrained by the limited uncertainty qua…
