Interval Set Clustering of Web Users with Rough K -Means
Pawan Lingras,Chad West +1 more
TL;DR: A variation of the K-means clustering algorithm based on properties of rough sets is proposed, which represents clusters as interval or rough sets.
Journal ArticleDOI
Estimation of missing traffic counts using factor, genetic, neural and regression techniques
TL;DR: In this paper, the authors used a combination of GA and ARIMA models to predict missing values of permanent traffic counts (PTCs) and found that GA-based regression models had the most accurate results.
Journal ArticleDOI
Soft clustering -- Fuzzy and rough approaches and their extensions and derivatives
TL;DR: This article compares k-mean to fuzzy c-means and rough k-Means as important representatives of soft clustering, and surveys important extensions and derivatives of these algorithms.
Journal ArticleDOI
Interpretations of belief functions in the theory of rough sets
Yiyu Yao,Pawan Lingras +1 more
TL;DR: This paper reviews and examines interpretations of belief functions in the theory of rough sets with finite universe and considers the notion of interval algebras, which may be used to interpret any belief functions.
Journal ArticleDOI
Data mining using extensions of the rough set model
Pawan Lingras,Yiyu Yao +1 more
TL;DR: It is demonstrated that a generalized rough set model can be used for generating rules from incomplete databases and these rules are based on plausibility functions proposed by Shafer.
