“…The resulting accuracy value is 93.55% through various stages, including hyperparameter tuning and feature selection [7]. Other studies that have been done previously are also making use of supervised machine learning to forecast lithology, such as support vector machines, decision trees, multi-layer perceptrons, random forests, and extreme gradient boosting, which show accuracy values above 80% [8]. From the previous experimental results, this study tries to evaluate the accuracy and performance of gradient boosting in the case of determining the sonic log value or DTCO.…”

“…Liu et al, 20 Jiang et al, 21 and Sun et al 22 23 identified lithology using a gradient-boosted decision tree (GBDT) algorithm in 2021, demonstrating excellent classification performance. Kumar et al 24 in 2022 applied a range of supervised machine learning techniques to interpret horizons from geophysical logs, with all models showing over 88% accuracy. Mishra et al, 25 also in 2022, combined correlation tools with machine learning for lithology prediction, surpassing traditional methods, like knearest neighbors, support vector regression (SVR), and multiple regression.…”

“…It implements machine learning algorithms under the Gradient Boosting framework and provides parallel tree boosting to solve many data science problems in a fast and accurate way. For example, recent application of XGBoost in lithology identification from geophysical logs has been achieved (e.g., Kumar et al., 2022; Zhang et al., 2022). ConvXGB method combines the performance of the CNN and XGBoost, two outstanding ML methods, and provides more precise output by integrating CNN as a trainable feature extractor to automatically operate feature learning with input, and XGBoost as a recognizer in the top level of the network to predict the labels, which has the premier combination of prediction performance and processing time compared with other algorithms (e.g., Pardede et al., 2019; Ren et al., 2017; Thongsuwan et al., 2021).…”
