A Cluster Algorithm Identifying the Clustering Structure

2008 International Conference on Computer Science and Software Engineering, 2008
Cluster analysis is a primary method for database mining. Most of clustering algorithms require input parameters which are hard to determine but have a significant influence on the clustering result. Furthermore, for many real-datasets there does not exist a global parameter setting for which the result of the clustering algorithm describes the ...

A Robust Information Clustering Algorithm

Neural Computation, 2005
We focus on the scenario of robust information clustering (RIC) based on the minimax optimization of mutual information (MI). The minimization of MI leads to the standard mass-constrained deterministic annealing clustering, which is an empirical risk-minimization algorithm.

On the Abstraction of a Categorical Clustering Algorithm

2016
Despite being one of the most common approach in unsupervised data analysis, a very small literature exists on the formalization of clustering algorithms. This paper proposes a semiring-based methodology, named Feature-Cluster Algebra, which is applied to abstract the representation of a labeled tree structure representing a hierarchical categorical ...
