A computer-implemented method for determining a boundary for binary
classification includes providing a data set, initializing a value for
noise in the data set, and determining a hyperplane dividing the data set
and a slack variable given a current value for noise. The method further
includes updating the value for noise and the slack variable given the
hyperplane, and determining the hyperplane to be the boundary for binary
classification of the data set upon determining a termination criterion
to be met, wherein elements of the data set are classified according to
the boundary.
