Compressionbased similarity
WebFeb 1, 2012 · Compression-based similarity measures The most widely known and used compression based similarity measure for general data is the Normalized Compression Distance (NCD), proposed by Li et al. [1]. WebThe method is comprehensively eval-uated with a test set of classical music variations, and the highest achieved precision and recall values suggest that the proposed method can be applied for similarity measuring.

WebJul 13, 2007 · Background: Similarity of sequences is a key mathematical notion for Classification and Phylogenetic studies in Biology. It is currently primarily handled using alignments. However, the alignment methods seem inadequate for post-genomic studies since they do not scale well with data set size and they seem to be confined only to … WebJul 24, 2011 · These files are taken to contain all of their meaning, like genomes or books.

WebThe theoretical justification for such methods has been founded on an upper bound on Kolmogorov complexity and an idealized information space. An alternate view shows compression algorithms implicitly map strings into implicit feature space vectors, and compressionbased similarity measures compute similarity within these feature spaces. WebJun 9, 2011 · Abstract: This paper proposes to use compression-based similarity measures to cluster spectral signatures on the basis of their similarities. Such universal distances estimate the shared information between two objects by comparing their compression factors, which can be obtained by any standard compressor.

Such a measurement should not be application dependent or arbitrary. A reasonable definition for the similarity between two objects is how difficult it is to transform them into each other. trt alagoas aocp
