改进PSO训练的BPNN方法的舰船主尺度建模
Modeling of the principal dimensions of large vessels based on a BPNN trained by an improved PSO
摘要
Abstract
A back propagation neural network (BPNN) trained by an improved particle swarm optimization (PSO) was applied to the principal dimensions of large vessels by regression analysis.First,the improved PSO learning factors concerning the iterative process were adjusted adaptively and the BPNN trained process was optimized by using an improved PSO.Secondly,a new BPNN method was applied to establish a mathematic model of an aircraft's principal dimensions (including overall length,breadth moulded,length of the design waterline,breadth of the design waterline,draft,and full load displacement).Finally,compared with the results of traditional polynomial regression,a BPNN trained by an improved PSO has higher accuracy and fine characteristics of smooth at every subsection.Therefore,the mathematic model has a guidance effect on the scheme demonstration and overall design of large vessels.关键词
