The aim is to develop a robust lithology classification model that accounts for outliers and variable data distributions across locations.
Proposed a coarse-to-fine framework integrating outlier detection and classification using an extremely randomized tree-based classifier.
Implemented an unsupervised learning method for outlier detection in well-log datasets.
Conducted comparisons with baseline machine learning classifiers like random forest and gradient boosting.
The proposed framework achieved higher prediction accuracy for sandstone lithologies than baseline classifiers.
Demonstrated effectiveness on two real-world well-logging datasets, enhancing model reliability.
Results indicated significant advantages in handling outliers during lithology classification.
