序列数据库 meaning in English
sequence library
Examples
- Because of the growing of time - series database and the potential significance of data mining , the research of data mining in time - series database has become a hotspot . at the same time , however , the nonlinear and chaotic characteristic of time - series data makes the mining be a difficult issue
由于时间序列数据库的日趋庞大及其挖掘的潜在意义,目前,时序数据挖掘研究已成为一个热点;然而,时间序列数据的非线性混沌特点,使得对它的挖掘成为难题。 - Although it can fulfill the queries and operations on the sequence data , it can not find the sequences or subsequences which have the same or approximately same pattern with the query sequences . it is necessary to extend the capability of the queries to find the hidden knowledge in the database
时间序列数据库描述、存储时间序列数据并提供各种查询操作,通常这些操作都是基于序列元素的值或者时间坐标进行的,无法实现对序列数据库中所蕴含知识的查询。 - General method of similar sequence mining based on time series is to transform time series into discrete character series and cluster them into different sets , then compute the euclidean distance between querying series and these sets to measure their similarity
摘要时间序列数据库中相似子序列的搜索,常用滑动窗口、分形插值逼近等方法将时间序列分割成各子序列,线性拟合各分段子序列,计算查询序列与各子序列的欧氏距离,满足距离阈值条件的为相似子序列。 - In order to improve the efficiency , we use the sampling points of the sequences to compute the distance of two sequences . the distance of sampling points is used to filter the sequence of the database , so the similarity searching space is reduced and the efficiency of the query is improved
在保持序列变化模式的前提下,使用抽样点来计算序列之间的dtw距离,并依据抽样比率和查询参数选择过滤距离对序列数据库进行过滤,实验结果表明,抽样过滤的方法明显提高了查询效率。 - With the arrival of the post - genome era and recent development of new , high - throughput technologies to mine data in biology , vast amounts of sequence data are flooding the dna and protein databases so rapidly that there is a strong need for efficient as well as effective computational tools to handle these data
随着后基因组时代的到来以及一些新的高通量信息提取技术的开发, dna和蛋白质序列数据库中的信息量以爆炸式增长。生命科学研究已经进入了深深依赖计算机和网络的时代。在所有的计算机工具中,多序列对齐占据核心地位。
