At the same time, the simple independent and identically distributed GGD models can be more robust and efficient than subband-dependent GGD models.

研究表明，自然图像多重子带的边缘分布能充分地反映其特征，而广义高斯分布建模在变换域中被认为是对自然图像最逼近和最成功的边缘分布建模方式。

Traditional statistical process control charts assume that observations are independent and identically distributed.

常规统计控制图的基本假设前提是观测值独立同分布，而在实际生产过程中，质量指标值常表现出自相关现象，违背独立性假定。

It is shown that the decrease of reliability is evident when longitudinal probability distributions of cross sections of unbonded prestress tendons are considered, and the index of reliability is reduced with the increase of the number of independent and identically distributed random variables.

结果表明，考虑无粘结预应力筋截面积沿长度方向的分布特性而引起的可靠指标的降低比较明显，可靠指标随着独立同分布随机变量的数目的增大而减小。

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。

While the above two papers mainly focus on how to model the spatial relations of variables on a field, IGM targets at learning the distribution of data variables that are independently and identically distributed.

上面这两类模型研究的范畴属于空间统计邻域，而IGM是一种用来学习随机向量分布的模型。

ABSTRACT In the nonhomogeneous environments, the performance of space time adaptive processing proposed by Brennan often declines sharply due to the fact that it is lack of independent identically distributed train samples.

在非均匀环境下，由于缺乏足够的与待检测样本中干扰独立同分布的训练样本，常规统计空时自适应处理方法的性能往往会急剧下降，因此能。。。

The traditional unitary space-time modulation system is generally based on the assumption of independent and identically distributed channel coefficients. However, this condition is hard to satisfy in practice, the spatial correlation among antennas deteriorates the performance.

传统的酉空时系统，通常假设信道衰落系数之间相互独立，这个条件在实际系统中却很难满足，天线之间的空间相关性造成系统性能恶化。

In recent works on sign language recognition,Hidden Markov Models has played an important role.But the framework of HMMs makes an assumption that the observations in the same state are independent and identically distributed,which is not consistent with sign language signals sometimes.

在近些年的手语识别工作中，隐马尔可夫模型（Hidden Markov Models，简称HMMs）起到了重要的作用，但是，HMMs假设同一状态内的观察值之间是独立同分布的，这个假设同某些手语信号的帧间相关性相背离。

For the longitudinal probability distributions of cross sections of unbonded prestress tendons, it is evident that the reliability index of unbounded prestressed concrete members decreases with the number of independent and identically distributed random variables decreases.

分析结果表明，体外无粘结预应力钢筋截面面积沿长度方向的变化，引起结构可靠指标的降低是比较明显的，可靠指标随着独立同分布随机变量的数目的增大而减小。
