Abstract
Clustering is partitioning a set of observation into groups called clusters, where the observation in
the same group has a common characteristic. One of the best known algorithms for solving the microarrays data
clustering problem using minimum spanning tree (MST) is CLUMP algorithm (Clustering algorithm through
MST in Parallel) which identifies a dense clusters in a noisy background. The MST construction phase of the
CLUMP is the time consuming phase. This paper presents an improved version of CLUMP algorithm called
iCLUMP (improved Clustering algorithm through MST in Parallel). iCLUMP enhances the speedup of MST
construction using the cover tree data structure. The implementation shows that iCLUMP is efficient than
CLUMP in terms of complexity and runtime.
