Physics-Informed Neural Networks to Develop Site-specific Pedotransfer Functions

Pedotransfer functions (PTFs) are widely used to estimate soil hydraulic properties based on easily accessible soil information, playing an important role in the parameterization of earth surface models.The “SPTF_SUR.py” script serves as an integrated suite of SPTF models and surrogate models. The “SPTFs.ipynb” script presents a case study for the definition, training, and evaluation of SPTF(FXW-M3), incorporating relevant data and technical details. (python>=3.11, pytorch>=2.0.0)
