The main objective of this study is to evaluate and compare the performance different machine learning (ML) algorithms, namely, Artificial Neural Network (ANN), Extreme Learning Machine (ELM), Boosting Trees (Boosted) considering influence various training testing ratios in predicting soil shear strength, one most critical geotechnical engineering properties civil design construction. For aim, a database 538 samples collected from Long Phu 1 power plant project, Vietnam, was utilized generate datasets for modeling process. Different (i.e., 10/90, 20/80, 30/70, 40/60, 50/50, 60/40, 70/30, 80/20, 90/10) were used divide into assessment models. Popular statistical indicators, such as Root Mean Squared Error (RMSE), Absolute (MAE), Correlation Coefficient (R), employed predictive capability models under ratios. Besides, Monte Carlo simulation simultaneously carried out proposed models, taking account random sampling effect. results showed that although all three ML performed well, ANN accurate statistically stable model after 1000 simulations (Mean R = 0.9348) compared with other Boosted 0.9192) ELM 0.8703). Investigation on greatly affected by training/testing ratios, where 70/30 presented best Concisely, herein an effective manner selecting appropriate predict strength accurately, which would be helpful phases construction projects.

Floods are one of nature's most destructive disasters because the immense damage to land, buildings, and human fatalities. It is difficult forecast areas that vulnerable flash flooding due dynamic complex nature floods. Therefore, earlier identification flood susceptible sites can be performed using advanced machine learning models for managing disasters. In this study, we applied assessed two new hybrid ensemble models, namely Dagging Random Subspace (RS) coupled with Artificial Neural Network (ANN), Forest (RF), Support Vector Machine (SVM) which other three state-of-the-art modelling susceptibility maps at Teesta River basin, northern region Bangladesh. The application these includes twelve influencing factors 413 current former points, were transferred in a GIS environment. information gain ratio, multicollinearity diagnostics tests employed determine association between occurrences influential factors. For validation comparison ability predict statistical appraisal measures such as Freidman, Wilcoxon signed-rank, t-paired Receiver Operating Characteristic Curve (ROC) employed. value Area Under (AUC) ROC was above 0.80 all models. modelling, model performs superior, followed by RF, ANN, SVM, RS, then several benchmark approach solution-oriented outcomes outlined paper will assist state local authorities well policy makers reducing flood-related threats also implementation effective mitigation strategies mitigate future damage.

Predicting and mapping fire susceptibility is a top research priority in fire-prone forests worldwide. This study evaluates the abilities of Bayes Network (BN), Naïve (NB), Decision Tree (DT), Multivariate Logistic Regression (MLP) machine learning methods for prediction across Pu Mat National Park, Nghe An Province, Vietnam. The modeling methodology was formulated based on processing information from 57 historical fires set nine spatially explicit explanatory variables, namely elevation, slope degree, aspect, average annual temperate, drought index, river density, land cover, distance roads residential areas. Using area under receiver operating characteristic curve (AUC) seven other performance metrics, models were validated terms their to elucidate general behaviors Park predict future fires. Despite few differences between AUC values, BN model with an value 0.96 dominant over predicting second best DT (AUC = 0.94), followed by NB 0.939), MLR 0.937) models. Our robust analysis demonstrated that these are sufficiently response training validation datasets change. Further, results revealed moderate high levels susceptibilities associated ~19% where human activities numerous. resultant maps provide basis developing more efficient fire-fighting strategies reorganizing policies favor sustainable management forest resources.
