The outbreak of water-bloom is the result of coactions of water body's physical, chemical, biologic and other progresses. It is very difficult to establish uniform mathematical model to efficiently evaluate and predict the water-bloom because of the water body's biodiversity and nonlinearity. Based on the foundation of research in the mechanism of water-bloom and the main component analysis in rivers...
Process neural network (PNN) is a new type of artificial neural network studied in recent year. PNN is an extent of traditional neural network, in which the inputs and outputs may be time-variation. Some modified algorithms for raising the training speed of PNN were investigated emphatically. These algorithms were based on function orthogonal basis expansion which exist low-speed convergence in network...
