An improved sequential search multistage vector quantizer
David J. Miller, Kenneth H. Rose · 2002
A new structure permits improved solutions which approximate the exhaustive-search multistage solution. A deterministic annealing design method capitalizing on this structure is formulated within the framework of information theory. The sequential search constraint is included as a prior, and the principal of minimum cross entropy is invoked. The method obtains improvement over both the standard sequential design and joint optimization approaches.>
