    An ultrasonic-AI hybrid approach for predicting void defects in concrete-filled steel tubes via enhanced XGBoost with Bayesian optimization by Shuai Wan, Shipan Li, Zheng Chen, Yunchao Tang

    Published 2025-07-01
    “…Based on 3600 ultrasonic measurement samples, an Extreme Gradient Boosting (XGBoost) model was enhanced through oversampling and hyperparameter optimization via Bayesian optimization (BO-XGBoost). The BO-XGBoost model demonstrated superior performance compared to baseline models (Random Forest, AdaBoost, and Gradient Boosting Decision Tree), achieving an overall prediction accuracy of 0.92, precision and recall of 0.90, and an AUC of 0.98. …”

    Uncertainty Quantification for Machine Learning‐Based Ionosphere and Space Weather Forecasting: Ensemble, Bayesian Neural Network, and Quantile Gradient Boosting by Randa Natras, Benedikt Soja, Michael Schmidt

    Published 2023-10-01
    “…In this paper, we implement and analyze several uncertainty quantification approaches for an ML‐based model to forecast Vertical Total Electron Content (VTEC) 1‐day ahead and corresponding uncertainties with 95% confidence intervals (CI): (a) Super‐Ensemble of ML‐based VTEC models (SE), (b) Gradient Tree Boosting with quantile loss function (Quantile Gradient Boosting, QGB), (c) Bayesian neural network (BNN), and (d) BNN including data uncertainty (BNN + D). …”

    Comparison of Three Statistical Downscaling Methods and Ensemble Downscaling Method Based on Bayesian Model Averaging in Upper Hanjiang River Basin, China by Jiaming Liu, Di Yuan, Liping Zhang, Xia Zou, Xingyuan Song

    Published 2016-01-01
    “…To improve the simulation accuracy of downscaling methods, the Bayesian Model Averaging (BMA) method combined with three statistical downscaling methods, which are support vector machine (SVM), BCC/RCG-Weather Generators (BCC/RCG-WG), and Statistics Downscaling Model (SDSM), is proposed in this study, based on the statistical relationship between the larger scale climate predictors and observed precipitation in upper Hanjiang River Basin (HRB). …”

    Effect of non-pharmacological interventions on chemotherapy induced delayed nausea and vomiting for tumors: A systematic review and Bayesian network meta-analysis by Yongni Wang, Fang Wang, Feifei Hu, Fang Long

    Published 2025-03-01
    “…Methods: Four Chinese databases (CNKI, Wanfang Data Knowledge Service Platform, VIP, Sinomed) and five English databases (PubMed, Cochrane Library, Embase, Web of Science, CINAHL) were searched from the establishment of the database to April 2024. A Bayesian network meta-analysis was performed on the response rate to the improvement of chemotherapy induced delayed nausea and vomiting, as well as improvement in KPS score, under different non-pharmacological interventions by using R 4.4.0 software and the GeMTC package. …”
