白化处理 meaning in English
whitening process
Examples
- By whitening the covariance matrix of flat ambiguity , correlation between ambiguity components , the number of local extrema of cost function is reduced . the search program getting into precocity is avoided by suitable encoding and genetic operation
通过白化处理模糊度，减少模糊度搜索中指标函数的局部极值点，采用适当的编码和遗传操作使得在种群个体较少的情况下避免搜索陷入早熟。 - To this paper we were carried tentatively on spectrum whitening in prestack , and each section after division scale is processed with spectrum whitening , particularly the composition of high frequency is raised apparently , the signal - noise ratio of high frequency raise . the resolution of whole section is better than stack
本文还尝试性地在叠前进行谱白化处理，对分尺度后的各个记录分别进行谱白化，尤其是高频成分提高得很明显，有效地提高了高频信噪比，整个剖面的分辨率明显增强。 - Most current algorithms only work well in special conditions , because of the abnormity of signals in the real world . now , the research in the ica arises much passion and the ica has brought about many applications . the primary results the writer has got are as the following : after a whiting process , it is a key to find an orthogonal matrix to throw away the high - order redundant information between components
由于现实生活中信号十分不规则,目前提出的算法大多只能针对某类信号分离,鉴于目前在ica方面极大的研究热情和强大的背景支持,作者对ica离线算法做了一定研究,主要内容和工作包括如下: ica问题经过白化处理后,寻找去除高阶相关的正交矩阵成为问题关键,而正交矩阵具有特殊的空间结构,组成它的每个列向量可视作rn中单位超球表面上一点,当这些点彼此垂直时,整体就组成一个正交矩阵。
