Journal ArticleDOI
A novel deep learning neural network approach for predicting flash flood susceptibility: A case study at a high frequency tropical storm area.
Dieu Tien Bui,Nhat-Duc Hoang,Francisco Martínez-Álvarez,Phuong Thao Thi Ngo,Pham Viet Hoa,Tien Dat Pham,Pijush Samui,Romulus Costache +7 more
TL;DR: It could be concluded that the proposed hybridization of GIS and deep learning can be a promising tool to assist the government authorities and involving parties in flash flood mitigation and land-use planning.
Journal ArticleDOI
A novel hybrid approach based on a swarm intelligence optimized extreme learning machine for flash flood susceptibility mapping
Dieu Tien Bui,Phuong Thao Thi Ngo,Tien Dat Pham,Abolfazl Jaafari,Nguyen Quang Minh,Pham Viet Hoa,Pijush Samui +6 more
TL;DR: A new soft computing approach that is an integration of an Extreme Learning Machine and a Particle Swarm Optimization, named as PSO-ELM, for the spatial prediction of flash flood susceptibility at high frequency tropical typhoon areas is proposed and validated.
Journal ArticleDOI
Effectiveness assessment of Keras based deep learning with different robust optimization algorithms for shallow landslide susceptibility mapping at tropical area
Viet-Ha Nhu,Nhat-Duc Hoang,Hieu Nguyen,Phuong Thao Thi Ngo,Tinh Thanh Bui,Pham Viet Hoa,Pijush Samui,Dieu Tien Bui +7 more
TL;DR: It is concluded that the Keras’s deep learning model is a new tool for shallow susceptibility mapping at landslide-prone areas and is better than those of the employed benchmark approaches of random forest, J48 decision tree, classification tree, and logistic model tree.
Journal ArticleDOI
Soil Salinity Mapping Using SAR Sentinel-1 Data and Advanced Machine Learning Algorithms: A Case Study at Ben Tre Province of the Mekong River Delta (Vietnam)
Pham Viet Hoa,Nguyen Vu Giang,Nguyen An Binh,Le Vu Hong Hai,Tien Dat Pham,Mahdi Hasanlou,Dieu Tien Bui,Dieu Tien Bui +7 more
TL;DR: It is concluded that the advanced machine learning models can be used for mapping soil salinity in the Delta areas; thus, providing a useful tool for assisting farmers and the policy maker in choosing better crop types in the context of climate change.
Journal ArticleDOI
A new intelligence approach based on GIS-based Multivariate Adaptive Regression Splines and metaheuristic optimization for predicting flash flood susceptible areas at high-frequency tropical typhoon area
Dieu Tien Bui,Nhat-Duc Hoang,Tien Dat Pham,Phuong Thao Thi Ngo,Pham Viet Hoa,Nguyen Quang Minh,Xuan-Truong Tran,Pijush Samui +7 more
TL;DR: The proposed hybrid PSO-MARS model outperformed other benchmark models in all the employed statistical measures and can be particularly suited for flash flood forecasting problems at high frequency tropical typhoon area.
