Similarity can be explained by different measures, like spatial distance (distance matrix), correlation, or comparison of local histograms or spectral properties (e.g. IXEGRAM). This technique is also applied for the search of a given pattern in a long data series as in gene matching. A similarity plot can be the starting point for dot plots or recurrence plots. ==Definition== To construct a self-similarity matrix, one first transforms a data series into an ordered sequences of feature vectors $V\; =\; (v\_1,\; v\_2,\; \backslash ldots,\; v\_n)$, where each vector $v\_i$ describes the relevant features of a data series in a given local interval. Then the self-similarity matrix is formed by computing the similarity of pairs of feature vectors :$S(j,k)\; =\; s(v\_j,\; v\_k)\; \backslash quad\; j,k\; \backslash in\; (1,\backslash ldots,n)$ where $s(v\_j,\; v\_k)$ is a function measuring the similarity of the two vectors, for instance, the inner product $s(v\_j,\; v\_k)\; =\; v\_j\; \backslash cdot\; v\_k$. Then similar segments of feature vectors will show up as path of high similarity along diagonals of the matrix. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Self-similarity matrix」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
