Predicting Standardized Streamflow index for hydrological drought using machine learning models
Shahabbodin Shamshirband,Sajjad Hashemi,Hana Salimi,Saeed Samadianfard,Esmaeil Asadi,Sadra Shadkani,Katayoun Kargar,Amir Mosavi,Narjes Nabipour,Kwok Wing Chau +9 more
TL;DR: Three indices of drought are modeled using Support Vector Regression, Gene Expression Programming, and M5 model trees and the results indicate that SPI delivered higher accuracy than SSI.
Journal ArticleDOI
Comparative study of multilayer perceptron-stochastic gradient descent and gradient boosted trees for predicting daily suspended sediment load: The case study of the Mississippi River, U.S.
Sadra Shadkani,Akram Abbaspour,Saeed Samadianfard,Sajjad Hashemi,Amirhosein Mosavi,Shahab S. Band,Shahab S. Band +6 more
TL;DR: In this article, three machine learning models (MLP, SGD, and GBT) were used to estimate the suspended sediment load (SSL) at the St. Louis (SL) and Chester (CH) stations on the Mississippi River, U.S.
Journal ArticleDOI
Hybrid models for suspended sediment prediction: optimized random forest and multi-layer perceptron through genetic algorithm and stochastic gradient descent methods
Saeed Samadianfard,Katayoun Kargar,Sadra Shadkani,Sajjad Hashemi,Akram Abbaspour,Mir Jafar Sadegh Safari +5 more
TL;DR: In this paper, the authors proposed a hybrid algorithm based on genetic algorithm and stochastic gradient descent (SGD) to predict suspended sediment concentration (SSC) in streams from two stations of Minnesota and San Joaquin rivers.
Journal ArticleDOI
Forecasting the discharge capacity of inflatable rubber dams using hybrid machine learning models
Wenyu Zheng,Shahab S. Band,Hojat Karami,Sohrab Karimi,Saeed Samadianfard,Sadra Shadkani,Kwok Wing Chau,Amir Mosavi,Amir Mosavi +8 more
TL;DR: Inflatable dams are flexible hydraulic structures that are constructed on rivers and are inflated by fluids such as air or water as discussed by the authors, and the effects of influential dimensionless structures have been investigated.
Journal ArticleDOI
Comparison of the efficacy of particle swarm optimization and stochastic gradient descent algorithms on multi-layer perceptron model to estimate longitudinal dispersion coefficients in natural streams
Tao Hai,Hongwei Li,Shahab S. Band,Sadra Shadkani,Saeed Samadianfard,Sajjad Hashemi,Kwok Wing Chau,Amir Mousavi +7 more
TL;DR: In this paper , the authors investigated the capabilities of machine learning methods such as multi-layer perceptron (MLP), multilayer perceptron trained with particle swarm optimization (MPLP-PSO), multi-Layer perceptron with Stochastic Gradient Descent deep learning (SGD) and different regressions including linear and non-linear regressions (LR and NLR) methods for determining the LDC of pollution in natural rivers and evaluated the accuracy of these methods in comparison with real measured data.
