Proceedings ArticleDOI
Mining top-n local outliers in large databases
TL;DR: A novel method to efficiently find the top-n local outliers in large databases using the concept of "micro-cluster" is proposed to compress the data.
Book ChapterDOI
Ranking outliers using symmetric neighborhood relationship
TL;DR: A simple but effective measure on local outliers based on a symmetric neighborhood relationship that considers both neighbors and reverse neighbors of an object when estimating its density distribution and shows that it is more effective in ranking outliers.
Journal ArticleDOI
TraClass: trajectory classification using hierarchical region-based and trajectory-based clustering
TL;DR: A feature generation framework TraClass for trajectory data is proposed in this paper, which generates a hierarchy of features by partitioning trajectories and exploring two types of clustering: (1) region-based and (2) trajectory-based.
Proceedings ArticleDOI
Substructure similarity search in graph databases
TL;DR: This paper investigates the issues of substructure similarity search using indexed features in graph databases, and develops a multi-filter composition strategy, where each filter uses a distinct and complementary subset of the features.
