Rappels sur la courbe ROC (Receiver Operating Characteristic Curve)
Supposons qu une population soit répartie en deux classes notées respectivement 1 et 0. Mais, au lieu d observer directement la classe à laquelle appartient un sujet, on dispose de renseignements sur chaque sujet, permettant d en déduire la classe à laquelle il appartient avec une certaine probabilité d erreur.

Description: 试者工作特征曲线 （receiver operating characteristic curve，简称ROC曲线），又称为感受性曲线（sensitivity curve）。得此名的原因在于曲线上各点反映着相同的感受性，它们都是对同一信号刺激的反应，只不过是在几种不同的判定标准下所得的结果而已。接受者操作特性曲线就是以虚报概率为横轴，击中概率为纵轴所组成的坐标图，和被试在特定刺激条件下由于采用不同的判断标准得出的不同结果画出的曲线。-PLOTROC Plot receiver operating characteristic.
Syntax
plotroc(targets,outputs)
plotroc(targets1,outputs1, name1 ,targets,outputs2, name2 , ...)
Description
PLOTROC(TARGETS,OUTPUTS) plots the receiver operating characteristic
for each output class. The more each curve hugs the left and top edges
of the plot, the better the classification.
PLOTROC(TARGETS1,OUTPUTS2, name1 ,...) generates multiple plots.

Description: 基于蒙特卡洛方法的主动声纳信号检测性能分析.主动声纳信号检测性能的分析上,目前在计算机仿真中一般假定混响包络的统计特性符合瑞利分布模型。基于此模型,已经有了较完善的理论。然而,在现代高分辨声纳系统中,混响包络的统计特性并不符合瑞利分布模型。此时在接收机工作特性分析时存在大量繁琐的公式推导。因此该文采用蒙特卡洛(M onte Carlo)统计试验方法,实现对瑞利分布混响背景下的主动声纳信号检测性能分析。结合对接收机工作特性曲线的仿真,得出了检测概率的理论值和仿真结果的误差曲线。误差曲线表明,蒙特卡洛方法在主动声纳信号检测的性能评估中是可行的。 更多还原
-Active sonar signal detection performance analysis, computer simulation is generally assumed that the statistical properties of the reverberation envelope distribution model of Rayleigh active sonar signal detection performance analysis based on the Monte Carlo method. Based on this model, has been a better theory. However, in the modern high-resolution sonar system, the statistical characteristics of the reverberation envelope does not comply with the Rayleigh distribution model. At this point in the receiver operating characteristic analysis, there is a lot of tedious formula derivation. In this paper, using the Monte Carlo (M onte Carlo) statistical test methods, active sonar signal detection performance analysis reverberation background Rayleigh distribution. The receiver operating characteristic curve simulation obtained the error curve of the theoretical value and the simulation results of the detection probability. The error curve shows that the Monte Carlo method in the assessm Platform: |
