It contrasts with causal decision theory, which requires a causal connection between your actions and the desirable outcome. ==Description== In a 1981 article, Allan Gibbard and William Harper characterized evidential decision theory as maximization of the expected utility $V$ of an action $A$ "calculated from conditional probabilities": :$$ V(A)=\sum\limits_ P(O_j | A) D(O_j), where $D(O\_j)$ is the desirability of outcome $O\_j$ and $P(O\_j\; |\; A)$ is the conditional probability of $O\_j$ given $A$. 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「Evidential decision theory」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.
