WebApr 11, 2024 · LightGBM has better performance than random forest and XGBoost in terms of computing efficiency and solving high-feature problems, and it may be considered an upgraded version of them. However, the research on using LightGBM to predict the burst pressure of corroded pipelines is still blank. ... Grid search, random search, and Bayesian ... WebFor this work, we use LightGBM, a gradient boosting framework designed for speed and efficiency. Specifically, the framework uses tree-based learning algorithms. To tune the model’s hyperparameters, we use a combination of grid search and repeated k-fold cross validation, with some manual tuning.
