Abstract(in English) | A Bayesian (Laplace or Krichevski-Trofimov) estimator for Markov source can be used to build a losslesssource code. However it achieves the first order asymptotic optimal redundancy, only when the actual predictiveprobabilities are all positive. In the other case, that is when the actual alphabet is unknown, we can modify theestimator into a zero-redundancy estimator. We have previously applied the idea in the finite window setting, andhave shown the first order asymptotic optimality of the redundancy, when the probability is positive on an unknownalphabet. Our work further proposes an estimator, in the same finite window setting, when the actual alphabet arestate wise unkown, which we believe is a useful case, and claims without proof the first order asymptotic optimalityof the redundancy. In this paper, we prove the last claim. |
