Linde–Buzo–Gray algorithm
 |
The Linde–Buzo–Gray algorithm (introduced by Yoseph Linde, Andrés Buzo and Robert M. Gray in 1980) 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;
