查询词典 prior

Since the Dirichlet distribution is the conjugate prior of the multinomial distribution, the beta distribution is the conjugate prior of the binomial distribution.

自的Dirichlet分布是共轭先验的多项分布， Beta分布是共轭先验的二项分布。

Methods According to the Bayesian conjugate prior distribution principle, the estimating methods of prior parameters of the conjugate beta distribution Be of the binomial distribution was given by writing the SAS programs.

根据贝叶斯共轭先验分布原理，对二项分布的共轭贝塔分布中的α、β两个先验参数的确定方法进行分析比较，编写SAS程序确定先验参数。

But usually, characteristic parameter of these methods has more requests for prior information of the signals, particularly for the prior estimate of signal noise ratio.

但是这些方法得到的特征参数，往往对于信号的先验知识有较多的要求，尤其是对信噪比的预先估计。

We will demonstrate the specification of reference prior distribution on the random covariance matrix. We will consider the approximate uniform shrinkage prior and approximate Jeffreys' prior. Both are formulated based on the approximated likelihood function. Under generalized linear mixed models, we show that the posterior mode under Jeffrey's prior is asymptotically closer to the REML estimate than the mode under uniform shrinkage prior does.

在广义线性混合模式下，我们证明了在样本数很大时，随机效应之变异数成份的后验众数和REML估计值会近似相等，同时也建立了后验众数和REML估计值的近似关系式，并提出了比较二种后验众数与REML估计值之间远近的准则。

C$2,500 good faith deposit paid prior to issuance of Invitation Letter. This is part of the C$75,000 paid prior to nomination, so the applicant will pay the remaining C$72,500 prior to receiving PNC.

在收到邀请函前要先付$2，500加币的居住保证金，这是在提名前需付的$75，000加币中的一部分，因此申请人将在收到提名纸前付剩馀的$72，500加币。

If SG-1 will shut down the wormhole that permanently blocks the Ori's supergate - the only bridge from their galaxy to the Milky Way - then he will use his Prior powers to steal an Ori ship, fly the sangraal into the Ori galaxy, and unleash it against the Ori.

如果SG1能够关闭永久阻止Ori超级星门的虫洞（连接Ori星系和银河系的唯一桥梁），他就可以用Prior的力量窃取一艘Ori战舰，将Sangraal送入Ori星系对付Ori。

Prior judicial authorization for this kind of limited investigation was unnecessary, because the strong public infterest in sanitation an the historic acceptance of such inspections outweighed the in dividual's interest in privacy.

Prior 司法授权为这有限的调查是多余的，因为强公开 infterest 在卫生方面历史的采纳的这样检查胜过了在 dividual。。s 兴趣在保密性上。

So Freedom is in the meditation Prior to attention, Prior to sleep, Prior to death, Prior to the body-mind.

因此自由在先于注意力的冥想中，先于深睡，先于死亡，先于这身-心。

The results showed that, on code evaluation performance, the effect of self-explanation was not significant between groups, but high prior knowledge learners outperformed low prior knowledge learners. On code generation performance, the guiding-question group outperformed the principle- prompt group and the control group. And the high prior knowledge group scored significantly higher than the low prior knowledge group. Finally, on the analysis of attitudes toward self-explanation activities, the guiding-question group showed more positive acceptance than the principle-prompt group.

研究结果发现：(1)在程式评估问题上，自我解释学习活动对学习成效没有显著影响，但高先备知识组则显著优於低先备知识组；(2)在程式设计问题上，问题引导组显著优於其余二组，高先备知识组亦显著优於低先备知识组；(3)在学习态度方面，问题引导组对自我解释学习活动的接纳程度和学习成效的看法上，皆显著高於原则提示组；两组对自我解释学习活动难度的看法则无显著差异。

In another personnel matter, Steinbrenner said he did not expect the Yankees to go after free-agent righthander Mark Prior.

在另外的人选方面，小老板说他不认为洋基会追求目前已成为自由球员的右投Mark Prior。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
