We make the
decision
|
|
|
boundaries
orthogonal to
|
|
one axis of the
space
|
|
|
and parallel to
all the
|
|
|
other axes.

This
is easy to
|
|
|
illustrate
in a 2-D
|
|
|
space
|

Then we can
locate the
|
|
|
region that a
datapoint
|
|
|
lies in using a
number of
|
|
|
very simple
tests that is
|
|
|
logarithmic in
the
|
|
|
number of
regions.
