noun
(statistics)
Let
mathbf
b
be
a
vector
and
define
the
support
operatorname
supp(
mathbf
b)=i:
mathbf
bᵢ≠0
where
mathbf
bᵢ
is
the
ith
element
of
mathbf
b.
Let
̂mathbf
b
be
an
estimator
for
mathbf
b.
Then
sparsistency
is
the
property
that
the
support
of
the
estimator
converges
to
the
true
support
as
the
number
of
samples
grows
to
infinity.
