A comparison of machine learning models for suspended sediment load classification

TL;DR: In this paper , the authors explored a new version of machine learning classifiers for sediment load classification at Johor River, Malaysia, using Extreme gradient boosting, random forest, support vector machine, multi-layer perceptron and k-nearest neighbors classifiers.
Journal ArticleDOI

Evaluation of spatial interpolation methods and spatiotemporal modeling of rainfall distribution in Peninsular Malaysia

TL;DR: In this article, the authors used Inverse Distance Weighting (IDW), Ordinary Kriging (OK), Geographical Weighted Regression (GWR) and Multi-scale Geographical weighted regression (MGWR) methods for the spatiotemporal analysis of rainfall pattern changes of Peninsular Malaysia due to climate change.
Journal ArticleDOI

Effect of high temperatures on the properties of lightweight geopolymer concrete based fly ash and glass powder mixtures

TL;DR: In this article , the influence of adding expanded clays (Leca) and crushed recycled bricks clay lightweight aggregates (RBA) on the fly ash and glass powder-based geopolymer concrete were investigated at ambient and high temperatures.
Journal ArticleDOI

Optimizing the Operation Release Policy Using Charged System Search Algorithm: A Case Study of Klang Gates Dam, Malaysia

TL;DR: The charged system search (CSS) algorithm model is developed in the present study to achieve optimum operating policy for the current reservoir and gives the steady-state probabilities of reservoir storage as output.
