Lithology identification based on interpretability integration learning

open access: yesEarth Science Informatics, 2023
Abstract A lithology intelligent identification interpretability model is proposed based on Ensemble Learning Stacking, Permutation Importance (PI) and Local Interpretable Model-agnostic Explanations (LIME). The method aiming to provide more accurate geological information and more scientific theoretical support for oil and gas resource ...
