查询词典 independent sampling

In the case where a set of observations can be assumed to be from an independent and identically distributed population, this can be implemented by constructing a number of resamples of the observed dataset (and of equal size to the observed dataset), each of which is obtained by random sampling with replacement from the original dataset.

与解析方法相比，bootstrapping 的优点在于，它无需对分布特性做严格的假定就能进行推断分析，这是因为它使用的分布就是真实数据的分布。

In this paper,we propose a novel model named distribution-free data density estimation,which is based on distribution-free(i.e.,independent of data distributions) sampling on global cumulative distribution to achieve high estimation accuracy with low estimation cost regardless of distribution models of the underlying data.

分布无关密度估计算法首先将底层数据的任意分布转换成一中间分布——累计概率分布函数。由于累计概率分布函数的输出在[0，1]之间均匀分布，因此接着对累计概率分布函数的输出随机采样，可以准确估计当前网络中数据的密度分布。

First, mathematical foundation of synchronization, i.e. the theory of parameter estimation is introduced. Then, DA/DD or NDA timing synchronization methods based on the ML estimation of timing parameter are presented. They are all widely applied in actual digital communication systems. Interpolation theory in digital signal processing has application in timing synchronization, which makes the sampling clock independent of the timing control so that timing adjustment is realized completely through digital disposal. The issue of interpolation in timing synchronization is discussed.

首先，介绍了定时同步实现的数学基础，即信号参数估计理论；从定时参数的最大似然估计出发，介绍了基于数据辅助的定时同步方法和基于非数据辅助的定时同步方法，他们在实际的数字通信系统中均有广泛应用；论文探讨了数字信号处理中插值理论在定时同步中的应用，它使得接收端的采样时钟独立于定时控制，定时调整完全通过数字处理方法得以实现。

Through the use of statistical methods of descriptive statistics, independent t-value test sampling, single factor variation analysis, Pilson differentiation correlation and gradual multi-regression, concrete conclusions are as the following

经由描述性统计、独立样本t检定、单因子变异数分析、皮尔森积差相关、逐步多元回归等统计方法加以分析后所获致之具体结论有

The method obtained multiple training samples from a single face image by multi channel sampling before two-dimensional independent component analysis transformation. Experimental results on the ORL face database and YALE face database show that the proposed method is feasible and has higher recognition performance compared with GREY, PCA, ICA, 2DICA, projection combined PCA, FLDA, sampled FLDA and other algorithms where only one sample image per person is available for training.

该方法是在2DICA运算之前，首先对单训练样本进行采样，通过多频率采样可以获取多个不同频率下的采样样本，然后对采样样本进行2DICA特征提取，最后采用神经网络分类识别，对人脸库ORL和YEL作了相关实验，将该方法与GREY、PCA、ICA、2DICA、PC PCA、FLDA、Sampled FLDA等传统方法作了比较，最终证明了该方法可以有效地解决单训练样本人脸识别的问题。
