信息量

Firstly, we constructed Red-Black Wavelet by Lifting Scheme. Secondly, we applied the Red-Black wavelet to two image fusion experiments: fusion of multifocus images; fusion of CCD and IR images. Finally, we evaluated the method's performance by some objective criteria based on statistics or informatics.

首先基于提升框架的思想构造Red-Black小波，然后将其应用于两组图像融合实验：不同聚焦点图像融合与可见光－红外图像融合；并分别采用基于统计特性和信息量的评价指标，将本文方法与db4张量积小波的图像融合方法进行了比较。

The advantage of this method lies in the reduction of data redundancy,and image quality and signal-to-noise ratio are improved.

该方法的优点在于去除了原始图像上的数据冗余，提高了融合后图像的信息量和信噪比。

However, depending on which motivation predominates, the informativeness of reported accounting numbers should vary.

This represents a fundamental mathematical limit on the best possible lossless data compression of any communication: considering a certain message as a series of realisations of a certain random variable (where the random variable can be "the next letter", or "the next word", or any other subdivision of text), the shortest number of bits necessary to transmit one message is the Shannon entropy of the corresponding random variable, multiplied by the number of realisations in the original text.

当然如果各个队夺冠的几率不等的话，那么熵则不会是5。因为如果从强队开始问问题，则不需要5个问题一般就可以得到答案。而根据哈夫曼编码的启发，我们表示这32个队，不需要平均长度为5的二进制位。从另外一个角度来看，熵作为信息量的大小也是表达能力的衡量，或者是不确定度的衡量和混乱程度的表现。为什么选择log来表示熵呢？如果X的表达能力为H，Y的表达能力为H，那么X+Y的表达能力应该是二者的乘积，所以H = H + H。

After analyzing the shortages of the existing algorithms for frequent pattern clustering,proposes an algorithm for creating compressed partial order based on pattern clustering function.Experiment result shows the compression arithmetic has higher proficiency and qualify,also can obtain much less number and much more information pattern.Thereby can find out more interesting of visited frequent sequential than the normal algorithm.

分析了现有频繁模式聚类算法的不足，提出了在模式聚类函数的基础上生成一个压缩的偏序的算法，实验结果显示该算法可以对频繁序列模式进行高效、高质量的压缩，可以得到数量更少、信息量更大的模式，从而提高发现的频繁访问序列的兴趣性。

The authors analyze the operation characteristic of distance protection of transmission line connecting wind farm with power grid under the variation of parameters such as the amplitude ratio of electromotive force at both sides, the phase difference of electromotive force at both sides, equivalent impedance of sources, system frequency and so on; based on the real-time current and electromotive force at wind farm side as well as the information of wind power generators participating power generation, a method to adaptively set the operation boundary of distance protection by use of the information at wind farm side only is proposed.
