摘要
采用无先验信息下的Bayes评估方法,利用常用的共轭分布作先验分布,对先验分布中超参数的取值范围做出假设,运用Bayes理论计算出故障检测率的Bayes估计。并以Bayes估计为基础,结合超参数,求出故障检测率的经验Bayes估计,最后,运用实验数据对所做出假设的合理性进行说明。
Adopt Bayes estimation method under non prior information condition, used common conjugate distribution to make prior distribution, the value ranges of the hyper-parameter in the prior distribution are assumed, and on the basis of Bayes, combine superparametric, experience Bayes estimation of fault detection rate is calculated. Lastly, the assumption is proved to be reasonable by the experimental data.
