An Optimization Model for Outlier Detection in Categorical Data
Zengyou He, Xiaofei Xu, Shengchun Deng
The task of outlier detection is to find small groups of data objects that are exceptional when compared with rest large amount of data. Detection of such outliers is important for…
Clustering Categorical Data Streams
Zengyou He, Xiaofei Xu, Shengchun Deng +1
The data stream model has been defined for new classes of applications involving massive data being generated at a fast pace. Web click stream analysis and detection of network int…
Modeling Complex Higher Order Patterns
Zengyou He, Xiaofei Xu, Shengchun Deng
The goal of this paper is to show that generalizing the notion of frequent patterns can be useful in extending association analysis to more complex higher order patterns. To that e…
A FP-Tree Based Approach for Mining All Strongly Correlated Pairs without Candidate Generation
Zengyou He, Xiaofei Xu, Shengchun Deng
Given a user-specified minimum correlation threshold and a transaction database, the problem of mining all-strong correlated pairs is to find all item pairs with Pearson's correlat…
