similarity index meaning in Chinese
相似性指标
相似性指数
Examples
- Community ' s p diversity is measured by whittaker similarity index
群落的多样性用whittaker指数测度。 - Note : the similarity coefficient is counted according to fd . szymkiewicz s similarity index of genus
注：表中相似系数是根据施姆凯维奇“属相似性指标”的计算方法计算。 - The average genetic distance in amphioxus was 0 . 1344 , and the range of genetic similarity indexes was from 0 . 78 to 0 . 96 , the average was 0 . 8656
计算其个体间遗传相似系数平均为0 . 8656 ，遗传距离平均为0 . 1344 。 - The method of sds - page was used to analyse the electrophoretic band of their seeds , and compare corydalis adunca maxim . living in gannan area with three kinds of corydalis straminea maxim living in different environments . by the principle of the higher of the similarity index of protein , the similarer of their blood relationship , author thought corydalis adunca maxim . living in gannan is the similarest with corydalis straminea maxim living in lunzhong area . then analysing the alkaloids in corydalis adunca
对这两种紫堇的种子进行了sds ? page凝胶电泳分析，根据蛋白质图谱，比较了甘南灰绿黄堇与三种不同产地的草黄堇的蛋白质相似度指数，依据相似度指数越高，种间的亲缘关系越接近的原则，认为甘南灰绿黄堇与陇中草黄堇的亲缘关系较近。 - The performance of similarity indexing structures in high dimensions degrades rapidly . in lower dimensional space , we often use lp - norm to measure the proximity between two points , but in many case the concept of this proximity is never meaningless in high dimensional space . these issues bring high dimensional data mining two challenges
随着数据维数的升高，高维索引结构的性能迅速下降，在低维空间中，我们经常采用l _ p距离作为数据之间的相似性度量，在高维空间中很多情况下这种相似性的概念不复存在，这就给高维数据挖掘带来了很严峻的考验，一方面引起基于索引结构的数据挖掘算法的性能下降，另一方面很多基于全空间距离函数的挖掘方法也会失效。
