| 摘 要： | 使用基于改进型人工免疫策略的优化算法,在统计相关的观测条件下,对固定融合规则的基于奈曼-皮尔逊准则的分布式多传感器决策融合系统进行优化设计。算法首先以筛选算子进行预搜索缩小范围,然后使用人工免疫策略方法进行全局搜索,计算过程无须使用目标函数的导数信息。对分布式多传感器决策融合系统的优化设计结果表明,优化算法在收敛性和精度上均优于传统梯度算法,并在此基础上对不同信号期望值下的最优融合规则进行了讨论。

| Abstract: | A method based on an improved artificial immune strategy is introduced for the optimization of distributed multi-sensor decision fusion systems under Neyman-Pearson criteria for the cases with statistically dependent observation and fixed fusion rule. The object function is optimized in two steps without any information of its derivation: filter operator is used for pre-search to reduce the search space and then an artificial immune strategy is applied for the global search. The experimental results show th... |
