Algorithm 3

(1) Get all the labeled data which belong to C from .
(2) Let denote these labeled data.
(3) Foreach  x in   do
(4) Compute density of data x,
(5) End Foreach
(6) Sort in descending order according to data
(7) While ( is not null)
(8) Take out the first data x from
(9) Compute
(10)    Foreach  y in   do
(11)  If  
(13)  Insert y into , and add y into
(14) End If
(15)    End Foreach
(16)    Delete x from
(17) End while
(18) Return
