Abstract (English) |
There are predictive and non-predictive algorithms in the Bayes codes. The CTW(Context TreeWeighting) algorithm has been interpreted as the non-predictive Bayes coding algorithm assuming a special prior distribution over context tree models. The two kinds of predictive Bayes coding algorithms using a fixed and an unlimited depth context tree were also proposed. The space complexity of the predictive Bayes coding algorithm using an unlimited depth context tree is O(t2) where t is the length of a source sequence. In this paper, we propose an efficient predictive Bayes coding algorithm using a new unlimited depth context tree whose space complexity is O(t). Moreover, the asymptotic code length of the Bayes coding algorithm using the unlimited depth context tree is investigated |
