统计独立性 meaning in English
independence statistical
statistical independence
Examples
- It fully exploits the fecg ' s special temporal property and its independence on other sources ( such as some noise , the maternal electrocardiogram ) ; therefore it is able to extract clearer fecgs , compared with existing algorithms
该算法充分利用了胎儿心电图与其他源信号（如各种噪声、母体心电图）的统计独立性，以及胎儿心电图在时城上的特殊结构等信息，因而能提取出更加清晰的胎儿心电图。 - The writer gives out a way , in which we take the magnitude of the independence between signals as parameters of some special kinds of functions , to measure the independence of signals from function optimization , and the values of these functions reflect the magnitude of the independence
本文从函数优化的角度出发,视统计独立性强弱为函数的“变量大小” ,构造一些特殊的函数,通过其函数值来反映独立性的强弱,其实用性有待检验。 - 2 ) by analyzing the information and conditional information description mechanism of system states , the problem of stochastic model reduction is investigated based on state aggregation . the information loss and conditional information loss between the full - and reduced - order models are measured by entropy , while the independence and conditional independence within me components of aggregated state are measured by kullback - leibler information distance . several model reduction methods for stable and unstable linear systems are derived by employing two criteria to get aggregation matrices : the minimal information loss and the maximal independence
2 )分析了随机系统状态空间模型中的信息和条件信息描述机制，以shannon熵为手段描述线性系统模型降阶过程中的信息和条件信息损失，以kullback - leibler信息作为衡量降阶模型状态向量各分量之间统计独立性的测度，针对稳定和不稳定系统研究基于状态集聚的模型降阶问题：分别运用最小信息损失准则和最大独立性原则，得出几种状态集聚的信息论方法，并讨论降阶模型的性质、阶次的确定、系统噪声分布特性等问题。 - The unique heat radiation of infrared image is generated from subcomponents . this paper analyses the natural feature of infrared image and the relationship between the shape and orientation with eigen vectors , gives the measure to classify infrared image based on object position to improve ability of compatibility in object recognition , moreover , applies the independent component for sub - region segmentation to construct new infrared image eigen vectors . the image features are processed by a support vector machine , and transform the binary svm to multi - object classifier
文中在传统红外热图像特征量的基础之上，通过分析红外热图像自身特性以及它的形成与其自身姿态的关系，提出了对目标物体红外热图像基于目标姿态的子分类，来提高目标识别中对姿态的容忍度；同时根据红外目标子部件对图像影响的统计独立性，使用独立元的方法对目标红外热图像进行了子区域分割，形成了新的红外图像特征量。 - Based on ica post processing matched filter multi - user detection lets the output of traditional matched filter to initialize the ica iterations , not only the known spread information of interesting user is used to overcome the uncertainness of ica , but also the character of statistical independence is used . the simulation results show that it advances the ability of traditional detector when the signal - noise - ratio is large . keywords code division multiple access ; independent component analysis ; channel estimation ; matched filter ; blind multi - user detection
基于ica后处理的匹配滤波多用户检测是用传统的检测器的输出来初始化ica的迭代，它不但充分利用多用户信号的已知信息，克服了ica的不确定性问题，同时也充分利用了多用户信号的统计独立性，仿真实验结果证明这种多用户检测算法在高信噪的情况下，误码性能改善随着信噪比的提高不断增加。
