چکیده
This paper examined the efficiency of artificial neural network (ANN) and multivariate linear regression (MLR) models in prediction groundwater quality parameters such as ecological risk index (ERI), pollution load (PLI), metal (MPI), Nemerow (NPI), geoaccumulation (Igeo). 40 samples were collected systematically analyzed for mainly heavy metals. Results revealed that adopting measured is effective modeling with high level accuracy. Contamination factor results reveal Ni, Zn, Pb, Cd, Cu have relatively low values < 1 within region while Iron ranged from contamination to very (> 6). PLI, MPI, ERI indicated pollution. NPI majority heavily polluted. Quantification most sample's was geogenically influenced. Igeo had extreme The health assessment children are substantially prone more than adults. ANN MLR showed a tendency ERI, Igeo. Principal component analysis appreciable variable loadings correlation matrix there exists weak positive amongst elements. Based on outcome this study, research recommends use they yielded positive, reliable, acceptable, appropriate accuracy performances.

Integration of artificial neural network and geographic information system applications in simulating groundwater quality
Background: Although experiments on water quality are time consuming and expensive, models are often employed as supplement to simulate water quality. Artificial neural network (ANN) is an efficient tool in hydrologic studies, yet it cannot predetermine its results in the forms of maps and geo-referenced data. Methods: In this study, ANN was applied to simulate groundwater quality ...

In the present study, two different data-driven models, artificial neural network (ANN) and multiple linear regression (MLR) models, have been developed to predict the 28 days compressive strength of concrete. Seven different parameters namely 3/4 mm sand, 3/8 mm sand, cement content, gravel, maximums size of aggregate, fineness modulus, and water-cement ratio were considered as input variables...
