查询词典 conditional entropy

In this study, on the basis of information theory and statistical methods, we use mutual information, n-tuple entropy and conditional entropy, combining with biological characteristics, to analyze the long range correlation and short range correlation in human Y chromosome palindromes.

本文中，我们利用信息论和统计学的方法并结合生物学的特征研究人类Y染色体回文序列的互信息、'n字'熵、条件熵，定量分析了回文序列的长程关联和短程关联，发现其中既存在长程关联，也存在短程关联，并且它们主要是由序列中的重复序列引起的。

The traditional HMM for Web information extraction is sensitive to the initial model parameters and easy to lead to a sub-optimal model in practice. A hybrid conditional model to combine maximum entropy and maximum entropy Markov model is put formard for Web information extraction.

针对传统Web信息抽取的隐马尔可夫模型对初值十分敏感和在实际训练中极易得到局部最优模型参数，提出了一种最大熵和最大熵马尔可夫模型相结合的条件模型。

When the conditional symmetric instability lies in the middle level and conditional instability in the lower and upper levels, the circulation will have updrafts through the total column of the atmosphere. The release of conditional instability gives rise to a mesoscale rain belt.

当低层和高层出现条件不稳定，中间呈条件对称不稳定或弱稳定度层结时，从低层到高层出现较深厚的垂直上升气流，湿重力不稳定能量的释放导致了云带的形成。

Second, the condition itself is almost always reversed (so that the jump to the 'else' block only takes place when the condition is not satisfied), and the primary conditional block is placed right after the conditional jump (so that the conditional code gets executed if the condition is satisfied).

第二，和单条件分支一样，条件声明与源代码中的条件声明也是相反的(道理同上：这样单条件不满足时就可以直接跳到else语句块中)而第一个跳转直接跟在条件声明之后。

In this paper,we give the concept of conditional independence by conditional probability and obtain some properties of conditional independence .

本文应用条件概率给出了条件独立的概念，得到了条件独立的相关性质。

It is composed of two parts, namely the contributions of enthalpy and entropy, and is the same as Koningsveld- Kleintijens' relation formally. But its entropy contribution χ~S is a complex function of concentration, rather than an arbitrary constant as proposed by Koningsveld.

它由焓贡献和熵贡献两部分组成，在形式上与Koningsveld-Kleintijen关系式相同，但它的熵贡献是浓度的复杂函数，而不象Koningsveld建议的是一个随意的常数。

In this paper, field entropy and Schrdinger-cat in the two-photon Jaynes-Cummings model with atomic motion are studied and the influences of the atomic motion and the field structure on the evolution of the field entropy and the generation of the Schrdinger-cat state are examined.

文章研究了具有原子运动的双光子J-C模型的场熵和薛定谔猫态，考察了原子运动和场结构对场熵和薛定谔猫态形成的影响。

In order to improve the correct rate of enterprise's financial distress prediction and reduce the sample number and training time, renyi-entropy and least squares support vector machine is applied to the field of financial distress prediction on the basis of the traditional support vector machine prediction model and advances a kind of prediction model which is based on Renyi-entropy and LS-SVM.

为了提高企业财务困境预测的正确率，减少训练模型的样本数和训练时间，在传统支持向量机预测模型的基础上，将Renyi熵和最小二乘支持向量机算法应用于财务困境预测，提出了一种基于Renyi熵的最小二乘支持向量机预测模型。

If we find time to marvel at the wonder of high entropy chess play and call it a great discoverer, the individual who devised high entropy chess play would then be the one truly deserving of such honor.

如果我们赞赏这个高熵赛棋的神奇功能，称高熵赛棋是一个伟大的发现者，那设计高熵赛棋的人，才是真正伟大的发明者。

Foods high in this vitamin include oily fish such as salmon, tuna and, and fish liver oils.
