More generally it is a categorical distribution in which the probability assigned to any label is of the above form It is possible to find a code defined on this distribution, which has an average code length that is equal to the entropy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dyadic distribution」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
