信息融合中的许多数据关联算法计算量大, 工程中难以保证实时性和有效性。本文就这一方面展开研究, 给出了可以满足工程实际需要的有效算法, 设计出相应的系统。通过实际系统应用, 可以获得满意的融合结果和较快的计算速度。(The comput ation quant ity of many data correlation algorithm is great in the information fusion. It is difficult to guarantee the computing speed and the validity in real time processing. By studying on this hand, this article launches the research, produces the effective algorithm suit to real engineering. The corresponding system is designed. Through the actual system application, the satisfaction the fusion result and a quicker comput ation speed is obtained.)

关于用遗传算法改进BP神经网络的matlab实现(转引) ga优化神经网权值&阈值程序。 优化的基本原理和过程很多论文可以查到，在此不必赘述我就把用gaot5的小程序贴在下面吧，也是y=1/x(为看的方便，比较繁杂的也有) (About matlab improved BP neural network using genetic algorithm implementation (quoted) ga optimizing neural network weights & Threshold Program. Optimization of the basic principles and procedures can be found in many papers, this does not have to go into details, I' ll stick with gaot5 small program below it, is y = 1/x (for watching convenience, there are also more complicated))
