查询词典 scale parameter

Actually, such a generalized Cauchy distribution was the Pearson VII probability distribution. In this dissertation, the Lorentz distribution was regarded as a generalized Cauchy distribution with only one scale parameter; while the Pearson VII distribution was regarded as a generalized Cauchy distribution with a scale and a shape parameter both.

因此，本文提出应在Lorentz分布的密度函数中再增加一个能够反映分布函数尾部特征的形状参数，希望通过该参数的可调节性进一步改善稀疏编码算法的自适应性。

根据这些特点，提出了一种方向Gabor滤波器参数的自动选取方法。根据楔特征人工指定纹理的大致方向，算法将环特征映射到Gabor滤波器的尺度参数，并按能量收敛原则搜索最好的尺度和纹理的准确方向。

The nonlinearity and discrete gradient inherited in CAViaR model is a conundrum for parameter estimation. We take the asymmetric Laplace distribution with scale parameter as the error process; indicate the variance has a minimum positive value when the scale parameter is a constant, conflicting with the distribution of real financial data. Further we estimate the parameters of indirect TARCH-CAViaR model base on Bayesian framework and Markov chain Monte Carlo method. The optimal scale parameter can also be obtained by Markov chain Monte Carlo method.

CAViaR一般模型中递归分位回归方程的非线性和非连续可微性是参数估计的一个难题，基于含有尺度参数的不对称拉普拉斯分布作为误差过程，指出将尺度参数固定为常数会导致不对称拉普拉斯分布随机变量的方差存在最小正值的限制，与实际金融数据分布不符；进而提出采用贝叶斯分析和马尔科夫链蒙特卡罗模拟方法，估计间接TARCH-CAViaR模型的参数，并可获得尺度参数的合理估计。

What's more,as far as the location-scale population is concerned,we show that the Fisher information matrix from an RSS sample is independent of the location parameter and is inversely proportional to the scale parameter.

本文进一步表明，对于位置-尺度分布族RSS样本下的Fisher信息矩阵与位置参数无关，与尺度参数成反比。

An edge-preserving parameter is introduced besides a scale parameter in the pseudosphere filter, and thus a better trade-off between image smoothing and edge locating can be obtained by using it.

在伪球滤波器中，除了尺度参数外，还引入了边缘保持参数，因而它能较好地解决传统滤波器的平滑性能与边缘定位精度之间的矛盾。

In the currently do not have to RIP imagesetter output software and be subject to any adjustment of the output film's site density value test results we can achieve business card printing and membership card making demands, which means the current RIP software and a parameter of the setter is in line with the current business card printing and membership card production requirements, are not required to be made of the relevant parameters are tuned, you can direct the output of a film that you want to test the value dot, and in the RIP software to convert "" gray-scale parameter is set to ensure that design business card printing and membership card production suites in a color swatch dot value and imagesetters actual output of the dot matches a color swatch.

在长远不有有差RIP输入软件和激光照排机举动任何调动的环境下，如果差所输入胶片的实地密度值尝试甘休能不亏到达制卡和会员卡制息的给求时，这表明长远的RIP软件与照排机的参数是相符长远制卡和会员卡制息给求的，不离不需给再差一些不关的参数举动调动了，可以间接差所输入的胶片举动网点百分比值的尝试，并在RIP软件洋举动"灰度变换"参数的撤销，以包管在安排制卡和会员卡制息版面时的各色块网点百分比值与照排机本质输入时的各色块网点百分比值分歧。
