信息失真对归一化压缩距离影响的评估

Evaluating the Impact of Information Distortion on Normalized Compression Distance

Ana Granados, Manuel Cebrian, David Camacho, Francisco de B. Rodriguez

摘要:

在本文中,我们应用不同的技术信息失真的一套经典的英文书籍。我们研究的影响,这些失真后的柯尔莫哥洛夫复杂性和压缩技术(后者基于归一化压缩距离,NCD)的聚类。我们将展示如何降低所考虑的书籍的复杂性,在其中引入几个修改。我们测量如何包含在每本书中的信息是使用聚类误差测量维护。我们发现实验,保持聚类误差的最佳方法是通过修改最频繁的单词。我们解释这些信息失真的细节,我们比较与其他种类的修改,如随机字失真和不频繁的字失真。最后,从不同的经验结果,已经进行了一些唯象解释。

英文摘要:

In this paper we apply different techniques of information distortion on a set of classical books written in English. We study the impact that these distortions have upon the Kolmogorov complexity and the clustering by compression technique (the latter based on Normalized Compression Distance, NCD). We show how to decrease the complexity of the considered books introducing several modifications in them. We measure how the information contained in each book is maintained using a clustering error measure. We find experimentally that the best way to keep the clustering error is by means of modifications in the most frequent words. We explain the details of these information distortions and we compare with other kinds of modifications like random word distortions and unfrequent word distortions. Finally, some phenomenological explanations from the different empirical results that have been carried out are presented.
