Back propagation(BP) is used to solve real world problems which use the concept of multilayer perceptron(MLP). BP have the disadvantage of trapped in local minima, slow convergence rate and more error prone. To optimize BP Algorithm, Particle swarm optimization(PSO) and Genetic algorithm(GA) is used. Limitation of PSO_Hill and PSO_A* is overcomes when these algorithms are combined and on the ba...
In this paper, we present an application of evolved neural networks using a real coded genetic algorithm for simulations of monthly groundwater levels in a coastal aquifer located in the Shabestar Plain, Iran. After initializing the model with groundwater elevations observed at a given time, the developed hybrid genetic algorithm-back propagation (GA-BP) should be able to reproduce groundwater ...
Abstract The Internet of Things, as an important part data aggregation, forwarding and control, is often subject to risks such eavesdropping or loss due the huge amount received data. Based on this, this paper introduces GA-LM-BP algorithm, BP network, LM-BP algorithm deep learning optimize by selects most suitable communication mode optimization algorithm. experimental results show that accura...
High-precision monthly runoff prediction results are of great significance to regional water resource management. However, with the changes in human activity, climate, and underlying surface conditions, sequence presents highly nonlinear random characteristics. In order improve accuracy prediction, this study proposed a model based on fuzzy information granulation (FIG) back propagation neural ...
The prediction of wind farm output power is considered as an effective way to increase the wind power capacity and improve the safety and economy of power system. It is one of the hot research topics on wind power. The wind farm output power is related to many factors such as wind speed, temperature, etc., which is difficult to be described by some mathematical expression. In this paper, Back P...
