資源簡(jiǎn)介

數(shù)據(jù)挖掘(Data Mining)是一個(gè)多學(xué)科交叉研究領(lǐng)域,它融合了數(shù)據(jù)倉技術(shù)(Database)技術(shù),人工智能(Artificial Intelligence)、機(jī)器學(xué)習(xí)(Machine Learning)、統(tǒng)計(jì)學(xué)(Statistics)、知識(shí)工程(Knowledge Engineering)、面向?qū)ο蠓椒ǎ∣bject-Oriented)、信息檢索(Information Retrieval)、高信能計(jì)算(High-Performance Computing)以及數(shù)據(jù)可視化(Data Visualization)等最新技術(shù)的研究成果。 經(jīng)過十幾年的研究,產(chǎn)生了許多新概念和新方法,特別是近幾年,一些基本概念和方法趨于清晰,它的研究正向著更深入的方向發(fā)展。
