PhyRestore applies a physics-informed latent-factor framework to restore corrupted inputs in soil-loss modeling, leveraging known physical relationships rather than direct prediction. While the method shows promise for recovering high-magnitude changes under isolated data corruption, its utility diminishes when factors are jointly corrupted or fall outside training distributions. This work highlights the potential of integrating domain-specific physical constraints into machine learning models to enhance robustness in environmental monitoring tasks.
PhyRestore: Physics-Structured Latent-Factor Restoration
arXiv:2609.19776v1 Announce Type: new Abstract: Estimating temporal soil-loss change is challenging when physically meaningful input factors are noisy or corrupted, particularly because substantial changes are rare relative to the large number of locations exhibiting little change. We study this problem through the Revised Universal Soil Loss Equation (RUSLE) and introduce PhyRestore, a physics-structured latent-factor restoration framework. Rather than directly predicting soil-loss change or correcting a degraded physical estimate, PhyRestore restores corrupted physical factors and reconstructs temporal change through the known physical relationship. We evaluate PhyRestore in a watershed-scale bitemporal raster setting under isolated and simultaneous corruption of rainfall erosivity and cover management, comparing it with the degraded RUSLE estimate and Direct RF, XGBoost, MLP, and CNN models. Factor restoration improves high-magnitude recovery when the corrupted factors remain identifiable, but its advantage weakens under joint corruption, sparse positive extremes, and factor values outside the training support.
