Optimal Estimation For Key Parameters Of The Marine Quality Model Using Data-Driven Neural Network, Ming-Chang Li, Shu-Xiu Liang, Zhao-Chen Sun, Guang-Yu Zhang

Journal of Marine Science and Technology

Marine water quality models are complicated because of their multi-parameter and multi-response characteristics. One major difficulty with water quality models is the accurate estimation of model parameters. In this paper, a new method based on a data-driven model (DDM) is developed to retrieve the value of model parameters. All training data are calculated by numerical water quality models from results of multiparameter matching design cases so the physical properties are not disturbed. The concept is to find the relationship between model parameters and the pollution concentration values of interior stations. Field data are imported into the relationship for inversing optimal …
