A method and device having instructions for analyzing input data-space by
learning classifiers include choosing a candidate subset from a
predetermined training data-set that is used to analyze the input
data-space. Candidates are temporarily added from the candidate subset to
an expansion set to generate a new kernel space for the input data-space
by predetermined repeated evaluations of leave-one-out errors for the
candidates added to the expansion set. This is followed by removing the
candidates temporarily added to the expansion set after the leave-one-out
error evaluations are performed, and selecting the candidates to be
permanently added to the expansion set based on the leave-one-out errors
of the candidates temporarily added to the expansion set to determine the
one or more classifiers.
