Algorithm 2

Semisupervised clustering algorithm with label propagation.
(1) Input the value of k.
(2) .
(3) Suppose that the number of different labels in is p.
(4) Merge into according
to labels of data in .
(5) Foreach cluster in   do
(6) Foreach data point x in C  do
(7)  Compute the
(8) End Foreach
(9) Compute s
(10) End Foreach
(11) Foreach cluster in   do
(13) End Foreach
(14) Label the rest unlabeled data according to KNN rule.
(15) Output the clustering results.
