Abstract
Clustering is an unsupervised learning and clustering results
are often inconsistent and unreliable when dierent clustering algorithms
are used. In this paper we have proposed a clustering ensemble frame-
work, named Object-Neighbourhood Clustering Ensemble (ONCE), to
improve the consistency, reliability and quality of the clustering result.
The core of the ONCE is a new consensus function that addresses the
uncertain agreements between members by taking the neighbourhood
relationship between object pairs into account in the similarity matrix.
The experiments are carried out on 11 benchmark datasets. The results
show that our ensemble method outperforms the co-association method,
when the Average linkage is used. Furthermore, the results show that
our ensemble method is more accurate than the baseline algorithm, and
this indicates that the clustering ensemble method is more consistent
and reliable than a single clustering algorithm.
