一種基于云理論的空間關(guān)聯(lián)規(guī)則提取算法

在空間關(guān)聯(lián)規(guī)則挖掘中，如何進(jìn)行定量定性轉(zhuǎn)換是一個(gè)十分關(guān)鍵的問(wèn)題，而云理論
正是一種處理該問(wèn)題的有效工具。文章提出了一種基于云模型的屬性空間軟化分方法，并且通過(guò)研究傳統(tǒng)的關(guān)聯(lián)規(guī)則挖掘方法和空間數(shù)據(jù)本身的特點(diǎn)，對(duì)Apriori 算法進(jìn)行了改進(jìn)，提出了更適用于對(duì)空間數(shù)據(jù)進(jìn)行挖掘的算法。最后通過(guò)實(shí)例測(cè)試，驗(yàn)證了改進(jìn)算法的有效性。

An Algorithm of Mining Spatial Association Rules based on Cloud Theory MENG Fan-rong ZHENG Zhong-pei CHEN Pei-pei (Computer Science and Technology Department, China University Of Mining And Technology,221008,China) Abstract: The transforms between qualitative concepts and their quantitative expressions plan an important role in spatial association mining，the cloud theory is this kind of powerful tools. In this paper, an attribute induction and concept promotion method on cloud model is proposed. By studying the methods of data mining and the? characters of spatial data，an improved spatial association rule mining algorithm based on Apriori is proposed. Finally an example is explained and confirmed this method validity.
