Uncertainty-Disentangled Probabilistic Stability Analysis in Wind Power Integrated Weak Grids
Samson S. Yu, Yinsong Chen
Conventional probabilistic small-signal stability analysis (PSSSA) propagates a single forecast distribution, conflating irreducible weather randomness (aleatoric) with reducible f…
A Posterior-Predictive Variance Decomposition for Epistemic and Aleatoric Uncertainty in Wind Power Forecasting
Yinsong Chen, Samson S. Yu, Kashem M. Muttaqi
Accurate wind power forecasting requires reliable uncertainty quantification, yet most existing methods report a single predictive uncertainty that conflates epistemic and aleatori…
A Unified Framework for Uncertainty-Aware Explainable Artificial Intelligence: A Case Study in Power Quality Disturbance Classification
Yinsong Chen, Samson S. Yu, Zhong Li +1
Post-hoc explainable AI (XAI) methods usually return one attribution map, even when the model represents uncertainty in its parameters. We define the \emph{explanation distribution…
Post-Hoc Uncertainty-Aware Explanations for Deployed Power Quality Disturbance Classifiers via Laplace Approximation
Yinsong Chen, Samson S. Yu, Kashem M. Muttaqi
Deep learning classifiers achieve high accuracy in power quality disturbance (PQD) recognition, but existing explanation methods return a single deterministic attribution map and p…
Addressing the Inconsistency in Bayesian Deep Learning via Generalized Laplace Approximation
Yinsong Chen, Samson S. Yu, Zhong Li +1
In recent years, inconsistency in Bayesian deep learning has attracted significant attention. Tempered or generalized posterior distributions are frequently employed as direct and…
