In the data extracting stage, aiming at interfacing of knowledge discovery algorithms to large database management systems, we present a family of generic, set - based, primitive operations for knowledge discovery in databases. we show how a number of well - known kdd classification algorithms can all be computed via our generic data extractors
該介面利用一組基於sql語言的數據抽取器實現為數據挖掘演算法抽取必要的統計數據，避免了直接對大型數據庫的數據進行調用，使得對大型數據庫進行快速數據挖掘成為可能。 -
The reason is " table ", this kind of expression for information, is so abstract and lopsided that massive valuable information are ignored and final analytic result for traffic management policymaker is one - legged ( statistical figures show : 85 % databases have geographical attribute data, such as urban road, traffic volume, traffic signs and markings and so on )
造成這種局面的主要原因就在於「表格」這種信息表達方式的抽象性、片面性，忽略了很多有價值的信息，最終給決策者呈現的分析結果不夠全面（統計結果表明， 85的數據庫中含有地理屬性數據如城市道路、交通流量、交通標志標線等） 。 -
However, in practical applications, considering cost in constructing the networks or management in networks, users prefer staring networks to net networks which do not meet their requirements. the dissertation proposes the c - dma algorithm to solve this problem, based on fdm and cd. experimental results show that the performance of the c - dma is available and extendable. ( 2 ) in the process of mining association rules, the quantitative attributes exit in databases
但是，在實際的網路應用環境中，用戶基於成本和管理等方面的需要，使用的網路結構往往是星型結構的，所以cd演算法和fdm演算法在網路結構和實際的網路結構不相適應，本文在cd演算法及fdm演算法的基礎上提出以中心結點結構的分散式關聯規則挖掘演算法，並且從演算法分析和模擬試驗兩個方面證明了演算法的有效性和可擴展性。 -
Finally the new methods are used to reduce the cleveland heart disease database from the uci repository of machine learning databases. the experiment results show that the new methods can obtain the better attribute reductions more effectively and efficiently
實例分析表明，文章提供的演算法能夠以較大的概率和較高的效率獲得較優的屬性約簡，具有良好的效果。 -
The numerical experiments on facial databases of orl and yale show the effectiveness of the proposed method
在orl人臉庫及yale人臉庫上的數據試驗，驗證了本文所提出方法的有效性。 -
Based on the strategy, the accessing functions for all entity types for relational databases are developed. used by the functions, the software can handle the persistency of product data in relational databases. examples show the validity of the research
基於這種訪問策略，開發了各種類型實體的關系數據庫訪問介面函數，實現了利用這些訪問介面函數對關系數據庫系統中的產品數據進行添加、刪除、修改和查詢等操作。 -
This list will only show databases that you have permission to view
此列表只顯示您具有查看權限的數據庫。 -
Experiments show that the matching scheme in this paper is much more close to human perception, and this technology is very suitable to construct and manage huge image databases
實驗表明，這種基於自適應分形編碼的圖像相似性判別方法和人的主觀判斷非常接近且計算簡單，適合於大型多媒體圖像數據厙的檢索，是一個非常有前景的圖像檢索方法。 -
It utilized advanced gis technology to manage regional agricultural resource information, build spatial and attribute databases, applied function of own spatial analyses and convenient making thematic picture of this system, realized dynamical show of correspondingly geographical position and regional agricultural resource information. and then this system had advantage in datum management, spatial analysis, graphic display
利用gis技術對區域農業資源信息進行管理，建立了空間和屬性數據庫，運用該系統特有的空間分析和方便的專題制圖功能，實現了區域農業資源信息數據與其相應的地理位置動態顯示，使該系統具有數據管理、空間分析和圖形顯示的優點。
