| Abstract(in English) | In universal source coding, the Ziv-Lempel (ZL) code and the Bayes code have been proposed. The improved types of the ZL code have been applied to data compression in practice. On the other hand, an efficient algorithm of the Bayes coding for FSMX model class has been proposed. The Bayes code has the good properties, such that asymptotic optimality and Bayes optimality. This implies that the Bayes code is superior to the ZL code for FSMX source from the viewpoint of compression rate. However, the fact such that the ZL code is often superior to the Bayes code for the practical data files have been reported. In this paper, we propose a new source model which emit word sequences and analyze the asymptotic performance of both codes for the proposed source models. |
