The local minima described the centers of the
clusters. According to the similarity measure (Jaccard
measure) of centre’s and documents frequency of all
documents would be associated with the desire
clusters and clusters are formed according to the
value of σ. Distribution of document matrix (x) in the
Hilbert space involves σ. The value of σ used to
describe the number of clusters that was to form after
completion of the process. In this work for clustering
we can’t know or give the number of clusters prior to
the clustering process. The value of σ computed by
input value of q using assumed formula as shown in
equation (6).
