| Abstract （English） |
Bayes codes have been proposed as universal lossless coding scheme for parametric source models. Some properties of Bayes codes for stationary sources are shown in previous researches. On the other hand, some universal codes for nonstationary sources have been proposed recently. Independent piecewise identically distributed (i.p.i.d.) sources are simple nonstationary sources that parameter changes discontinuously. In this paper, we define Bayes codes for i.p.i.d. sources. And we prove that Bayes codes minimize the mean redundancy for constrained i.p.i.d. class. |
