| Abstract(in English) | Bayes code is one of universal source codings, such that a class of the probabilistic model of source is known but the parameters of the probabilistic model are not known. Bayes code provides Bayes optimality in term of redundancy. Matsushima proposed Bayes coding algorithm for FSMX sources. In his algorithm, coding probability is calculated using a context tree. The algorithm, however, needs enormous memory if it encodes some sequences, because upper bound of required memory size is not less or equal to O(n) for sequence size n. In this paper, we propose Bayes coding algorithm for FSMX sources to reduce required memory size, and we investigate its performance. In addition, if we encode sequence x^n in our algorithm, required memory size is O(n). Time complexity of our algorithm is equivalent to Matsushima's algorithm. |
