| Abstract(in English) | In this paper, we present an efficient coding algorithm for a non-stationary source based on context tree models that very from section to section. The context tree model is the extension of Markov models, and it represents a wide source model class that each symbol's generation depends on past sequences. The source model we present is an extension of context tree models. The calculation of the Bayes codes for it needs weighted mean over all context tree models and all changing patterns of the models; hence, we provide an approach of reducing the amount of the calculation. |
