High-dimensional
data (e.g.
|
|
|
more than 100
dimensions)
|
|
|
• |
The
noise is not sufficient to
|
|
|
obscure
the structure in the
|
|
|
data
if we process it right.
|
|
|
• |
There
is a huge amount of
|
|
|
structure in the data, but the
|
|
|
structure
is too complicated to
|
|
|
be
represented by a simple
|
|
|
model.
|
|
|
• |
The main problem
is figuring
|
|
|
out a way to
represent the
|
|
|
complicated
structure so that it
|
|
can be learned.
