查询词典 sample distribution

In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.

在该算法中，期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量，由阵列接收信号计算出各候选波达方向的后验概率，并将后验概率的分布作为是否需要进行二次采样的判断标准；随后，对各波达方向上的波束成形权值线性加权，便可得到自适应波束成形器，权系数为各候选波达方向的后验概率值。

Real AdaBoost algorithm demands division of the sample space. The traditional finite division can not reflect the distribution of positive and negative samples.

连续AdaBoost算法要求对样本空间进行划分，传统的等距划分无法体现正负样本各自的分布规律。

This method was applied to the dimensionality reduction of multidimensional time series via projection pursuit technique for fuzzy clustering. According to the results of the classification and the extraction of fuzzy rules through best value projection, three types of fuzzy membership function were generated using trapezoid distribution method. Then the sample's credit level was determined according to the fuzzy approximability in computation.

该方法利用投影寻踪技术对多维时间序列数据进行降维处理并进行模糊分类；根据分类结果和最佳投影值提取模糊规则，采用梯形分布法生成三个模糊隶属函数；最后根据计算模糊贴近度确定样本的信用级别。

Based on the view of theory and engineering practice, this paper illustrates that the prior distribution of the small sub-sample products' success-failure sub-systems must beβ(1/2,1/2), and then the Bayes corrected formula for the reliability estimation of the total system is presented.

本文从理论上和工程实践上说明了小子样产品的成败型分系统验前分布应取为 b （1/2，1/2），从而给出了由分系统试验数据折合成系统试验数据的Bayes方法修正公式。
