Linde–Buzo–Gray algorithm
The
Linde–Buzo–Gray
algorithm
is a
vector quantization
algorithm to
derive
a
good
codebook
.
It is similar to the
k-means
method
in
data clustering
.
The algorithm
At each
iteration
, each
vector
is
split
into two new
vectors
.
A
initial
state:
centroid
of the
training sequence
;
B initial
estimation
#1:
code book
of
size
2
;
C
final
estimation after LGA:
Optimal
code
book
with 2 vectors;
D initial estimation #2: code book of size
4
;
E final estimation after LGA: Optimal code book with 4 vectors;
