• 
The line that
maximizes the minimum



margin is a good
bet.




– 
The
model class of “hyperplanes



with
a margin of m” has a low VC



dimension
if m is big.



• 
This
maximummargin separator is



determined by a
subset of the



datapoints.




– 
Datapoints
in this subset are



called
“support vectors”.




– 
It
will be useful computationally if



only
a small fraction of the



datapoints
are support vectors,



because
we use the support



vectors
to decide which side of the


separator
a test case is on.
