We applied the Extreme Gradient Boosting (XGBoost) algorithm to the data to predict as a binary outcome the increase or decrease in patients' Sequential Organ Failure Assessment (SOFA) score on day 5 after ICU admission. The model was iteratively cross-validated in different subsets of the study...
Therefore, this paper intends to develop a machine learning (ML) method to predict the maximum wall deflections of deep braced excavations in sand, which has not yet received much attention. To this end, an advanced ML model of extreme gradient boosting (XGBoost) is employed. The performance ...
XGBoost is an optimized distributed gradient boosting library designed to be highlyefficient,flexibleandportable. It implements machine learning algorithms under theGradient Boostingframework. XGBoost provides a parallel tree boosting (also known as GBDT, GBM) that solve many data science problems in a ...
Conclusions: The XGBoost model predicted the change in SOFA score in critically ill COVID-19 patients admitted to the ICU and can guide clinical decision support systems (CDSSs) aimed at optimizing available resources. KEYWORDS: Machine learning;Extreme gradient boosting (XGBoost);COVID-19;Multiple...
Relative humidity (RH) is one of the important processes in the hydrology cycle which is highly stochastic. Accurate RH prediction can be highly beneficial for several water resources engineering practices. In this study, extreme gradient boosting (XGBoost) approach “as a selective input parameter”...

This is an introductory document of using the xgboost package in R.xgboost is short for eXtreme Gradient Boosting package. It is an efficient and scalable implementation of gradient boosting framework by (Friedman, 2001) (Friedman et al., 2000). The package includes efficient linear model solver...
We used Extreme Gradient Boosting to predict power output. We see that it has better performance than linear model we tried in the first part of the blog post series. The RMSE with the test data decreased from more 4.4 to 2.8. See you in the next part of my machine learning blog post...
Explore the fundamentals of gradient boosting, with a focus on Regression with XGBoost, using XGBoost in pipelines and how to fine-tune your XGBoost model.
Over the time, the prediction accuracy of computational models for predicting miRNA–disease associations is continuously increasing. In search of a superior model over previous ones, we developed a machine learning-based model, Extreme Gradient Boosting Machine for MiRNA-Disease Association prediction (...
