摘要

一种新的结构允许改进的解接近穷尽搜索多阶段解。利用这种结构，在信息论的框架内提出了一种确定性退火设计方法。将序列搜索约束作为先验条件，并调用最小交叉熵原理。该方法比标准的顺序设计和联合优化方法都得到了改进

An improved sequential search multistage vector quantizer

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.<>
