This Eq. (
2.75
) is not exactly equal to the
L
1
-norm cost function, since the constraint
term is not equal to
j
=
1
|
but has form of
j
=
1
log
x
j
|
|
x
j
|
. Since these constraint
terms have similar properties, the solution obtained by minimizing this cost function
has a property very similar to the
L
1
-norm-regularized minimum-norm solution.
