sslMincut
implements the Mincut algorithm for maxflow graph partition in the k-nearest neighbor graph.
1 | sslMincut(xl, yl, xu, simil.type = "correlation", k = 10)
|
xl |
a n * p matrix or data.frame of labeled data |
yl |
a n * 1 binary labels(1 or -1). |
xu |
a m * p matrix or data.frame of unlabeled data. |
simil.type |
character string; this parameter controls the type of similarity measurement.(see |
k |
an integer parameter controls a k-nearest neighbor graph. |
sslMincut
creates a k-nearest neighbor graph and finds a maxflow
from the first postive observation to the first negative one based on MPLA algorithm. This
maxflow partitions the graph into postive labels and negative ones.
a m * 1 integer vector representing the predicted labels of unlabeled data.
