| Abstract(in English) | Recently, grammar based codes are researched in the area of lossless source coding. But, it is not clear which formal grammars is appropriate in Chomsky hierarchy for information compression. In this paper, we consider grammar based codes as the process of deriving automata based on machine learning and it is a purpose to clarify what influence the class of grammars or languages gives the encoding in the view of machine learning. I will show that Bayes algorithm outputs the shortest hypothesis in the class and some class has feasible complexity in order to ouput optimal hypothesis based on computational learning theory. |
