Vector quantization with optimized grouping of elements is studied. The presented vector quantization allows optimal or suboptimal grouping of source data. Thus, the algorithms herein are called variable region vector quantization. The optimization yielding the data subgroups can also be interpreted as the connection weight adjustmen. The presented methods are still executable on conventional SISD computers. However, the adaptation of the variable region vector quantization to SIMD and MIMD computation via PDP (Parallel Distributed Processing) approach motivates new computational concepts and tools. Here, a fine-grain MIMD computer is emulated and used for the variable region vector quantizer design. Experimental results on digital speech and images are given.
