SVM’s use each
training case, x, to define a feature K(x,
|
|
.) where K is
chosen by the user.
|
|
|
|
– |
So
the user designs the features.
|
|
|
• |
Then they do
“feature selection” by picking the support
|
|
|
vectors, and
they learn how to weight the features by
|
|
|
solving a big
optimization problem.
|
|
|
• |
So an SVM is
just a very clever way to train a standard
|
|
|
perceptron.
|
|
|
|
– |
All
of the things that a perceptron cannot do cannot
|
|
|
be
done by SVM’s (but it’s a long time since 1969 so
|
|
|
people
have forgotten this).
