3 . research of similar search in time series a novel method is proposed to fast search similar pattern in time series using full text index technique 3 )時(shí)間序列相似性查找研究為了在實(shí)際分析中對(duì)挖掘結(jié)果的運(yùn)用,本文還研究了時(shí)間序列的相似性查摘要找。
As to video content - based video index techniques , besides providing correct and quick response index result , a good video index should also provide content retrieval of correlation similarity 基于視頻內(nèi)容的視頻索引技巧,除了必須能提供正確而快速的反應(yīng)搜索結(jié)果外,一個(gè)好的視頻索引方法還必須提供相關(guān)相似性的內(nèi)容檢索。
The new index system is a new index technique combining fuzzy clustering classification theory and a new algorithm . result shows that this new index technique can query correctly and quickly 就浙江大學(xué)博士學(xué)位論文是結(jié)合模糊聚類分類理論與一種新算法整合的新索引方法,結(jié)果表明,新索引方法具有快速查詢與正確的查詢結(jié)果。
As the display of electronic multi - media military geographic documentations is based on multiple topographic maps , increasing the display of electronic maps with macro vector data is the chief problem to solve . the paper introduces the spatial index technique at detail for it 多媒體電子兵要地志以多幅地圖為顯示平臺(tái),海量數(shù)據(jù)電子地圖的快速顯示是面臨的首要問題,作者在文中詳細(xì)介紹了空間索引技術(shù)。
Simulation study shows 2 . 5db imd3 suppression can be improved compared with common polar lut predistorting system that has same 64 lut entries . besides the studying of indexing technique , the adaptive refresh algorithms of lut are studied and a new algorithm is obtained 仿真研究表明,在相同64位表項(xiàng)的極坐標(biāo)預(yù)失真系統(tǒng)中,對(duì)比幅度索引技術(shù)該新型索引技術(shù)可以提高2 . 5db的imd3壓縮性能,但不增加硬件實(shí)現(xiàn)成本。
Experiments shows , compared with the previous methods , the method is more simple , efficient and more applied value . 3 . research of similar search in time series a novel method is proposed to fast search similar pattern in time series using full text index technique 3 )時(shí)間序列相似性查找研究分析比較了根據(jù)時(shí)間序列與全文序列的異同,采用了全文索引技術(shù),首次提出了一種基于互關(guān)聯(lián)后繼樹的時(shí)間序列相似性查找方法。
