距离尺度 meaning in Chinese
distance scale
Examples
- Thus , given a query point , its k - nn search in high - dimensional spaces is transformed into the search in the single dimensional space with the aid of cdt index
该索引方法的提出基于以下观察:首先, nb - tree和idistance都是采用单距离尺度转化来缩小查询空间。 - Searching in high - dimensional spaces : index structures for improving the performance of multimedia databases . acm computing surveys , 2001 , 33 : 322 - 373 . 2 guttman a . r - tree : a dynamic index structure for spatial searching
本文试图将高维空间中的每个点对应的两种距离尺度通过线性组合的方式表达成复合距离尺度,从而能够较好地缩小查询空间,提高查询效率。
