| Abstract(in English) | Vector quantization is an attractive technique for lossy data compression, which has been a key technology for efficient data storage andlor transfer. So far, various algorithms have been proposed to design optimal codebooks presenting quantization with minimized errors. In particular, the Law-of-the-Jungle(LOJ) learning algorithm has been proposed to achieve rapid codebook design by algorithmic improvements. However, its acceleration is still required when large data sets are processed on a single computer. In order to achieve faster codebook design, we have been proposed a scalable parallel codebook design algorithm for parallel computers. This paper analyzes and evaluates the performance of the parallel LOJ learning algorithm on three types of parallel computers: an IBM SP2, an NEC AzusA and a PC cluster. |
