A Bayesian framework based on a Gaussian mixture model and radial-basis-function Fisher discriminant analysis (BayGmmKda V1.1) for spatial prediction of floods
Tien Bui, Dieu; Hoang, Nhat-Duc (Journal article; Peer reviewed, 2017)In this study, a probabilistic model,named as BayGmmKda, is proposed for flood susceptibility assessment in a study area in central Vietnam. The new model is a Bayesian framework constructed by a combination of a Gaussian ... -
A Novel Hybrid Approach Based on Instance Based Learning Classifier and Rotation Forest Ensemble for Spatial Prediction of Rainfall-Induced Shallow Landslides Using GIS
Nguyen, Quang-Khanh; Tien Bui, Dieu; Hoang, Nhat-Duc; Trinh, Phan Trong; Nguyen, Viet-Ha; Yilmaz, Isik (Journal article; Peer reviewed, 2017)This study proposes a novel hybrid machine learning approach for modeling of rainfall-induced shallow landslides. The proposed approach is a combination of an instance-based learning algorithm (k-NN) and Rotation Forest ... -
A New Approach of Hybrid Bee Colony Optimized Neural Computing for Estimation of Soil Compression Coefficient for Housing Construction Project
Samui, Pijush; Hoang, Nhat-Duc; Nhu, Viet Ha; Nguyen, My-Linh; Ngo, Phuong Thao; Tien Bui, Dieu (Peer reviewed; Journal article, 2019)In the design phase of housing projects, predicting the settlement of soil layers beneath the buildings requires the estimation of the coefficient of soil compression. This study proposes a low-cost, fast, and reliable ... -
A Novel GIS-Based Random Forest Machine Algorithm for the Spatial Prediction of Shallow Landslide Susceptibility
Dang, Viet-Hung; Hoang, Nhat-Duc; Nguyen, Le-Mai-Duyen; Tien Bui, Dieu; Samui, Pijush (Peer reviewed; Journal article, 2020)This study developed and verified a new hybrid machine learning model, named random forest machine (RFM), for the spatial prediction of shallow landslides. RFM is a hybridization of two state-of-the-art machine learning ... -
Novel Hybrid Swarm Optimized Multilayer Neural Network for Spatial Prediction of Flash Flood at Tropical Area Using Sentinel-1 SAR Imagery and Geospatial data
Phuong-Thao Thi, Ngo; Hoang, Nhat-Duc; Biswajeet, Pradhan; Quang Khanh, Nguyen; Xuan Truong, Tran; Quang Minh, Nguyen; Viet Nghia, Nguyen; Pijush, Samui; Tien Bui, Dieu (Journal article; Peer reviewed, 2018)Flash floods are widely recognized as one of the most devastating natural hazards in the world, therefore prediction of flash flood-prone areas is crucial for public safety and emergency management. This research proposes ...
