The PBIL algorithm is a combination of genetic algorithms and competitive learning, which maintains a probability vector about the search space and uses it to direct algorithm's exploration.

PBIL进化算法有效结合了简单遗传算法和竞争学习算法的特点，通过一个不断更新的且与搜索空间有关的概率矢量来指导算法的搜索，该概率矢量是整个进化过程的信息积累，用它指导产生的后代将会更加优秀。

Finally, it has been proved that a step learning function, which satisfies the condition of LMS algorithm, could make network weight converge with probability 1 to the feature vector.

并证明了SOFM网络的学习存在一表征特征矢量的稳定解，最后证明了一个满足LMS随机逼近收敛算法条件的步幅函数可使网络权值以概率1收敛于特征矢量。

The adaption is done during operation and occurs by means of a displacement of the stored midpoint vector of the probability density distributions of hidden Markov models, in the direction of a known feature vector of sound expressions and in relationship to the hidden Markov models specially used.

适应是在运行中完成的，并且是通过隐含式－马而科夫－模型的概率密度分布的被存储的中心矢量的一个位移发生的，是在一个被识别的发音表达的特征矢量方向上并且是参照应用的隐含式－马而科夫－模型。

The probability vector can be viewed as a prototype vector for generating solution vectors that have high evaluations with respect to the available knowledge of the search space. Compared with the general genetic algorithm, PBIL discards the complex and problem-correlation operators, which always affect the algorithm's performance highly.

相对于常规遗传算法，PBIL进化算法抛弃了复杂的且对算法性能影响很大的交叉、变异算子，而引入竞争学习的机制，以概率矢量的方式通过采样来产生下一代群体，然后选出群体中最优个体对概率矢量进行更新，直至最后收敛。

The dot product of a pseudovector and a vector is called a pseudoscalar.

一个赝矢量和一个矢量的标识称为赝标量。

As a result, the mass matrix, the stiffness matrix, the damping matrix and the excitation coefficient matrices of the dynamics differential equations are random parameter matrices. According to the minimum deviation rule of the mean squares between the random parameter system and the deterministic parameter system, the random mean square deviation vector function between the two systems has been set up and the deterministic parameter system has been solved.

It includes image preprocessing, graphics auto-recognition, graphics format conversion and human-computer interactive method, such as raster image edition and vector graphics edition.

它包括图像预处理、自动矢量化、图形格式转换以及人工交互方式的光栅图像和矢量图形编辑等功能。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
