A fuzzy k-modes algorithm for clustering categorical data
Zhexue Huang,Michael K. Ng +1 more
TL;DR: A new approach is developed, which allows the use of the k-means paradigm to efficiently cluster large categorical data sets and a fuzzy k-modes algorithm is presented and the effectiveness of the algorithm is demonstrated with experimental results.
Journal ArticleDOI
A Note on K-modes Clustering
Zhexue Huang,Michael K. Ng +1 more
TL;DR: This note demonstrates the equivalence of the two K-modes procedures and presents a nonparametric approach to deriving clusters from categorical data using a new clustering procedure called K-Modes.
Journal ArticleDOI
Data-mining massive time series astronomical data: challenges, problems and solutions
Michael K. Ng,Zhexue Huang +1 more
TL;DR: The major characteristics of the time series astronomical data, data preprocessing techniques to process these time series, and some domain-specific techniques to separate candidate variable stars from the nonvariant ones are presented.
