joint entropy

名詞

可算名詞 不可算名詞

(information theory) The Shannon entropy of a "script" whose "characters" are elements of the Cartesian product of the sets of characters of the component scripts.

日本語の意味

情報理論における結合エントロピー：各成分スクリプトの文字集合の直積をとることで得られる文字列全体のシャノンエントロピー。

To measure the uncertainty of paired observations, we modeled the data as a script whose characters are elements of the Cartesian product of the component scripts and calculated the joint entropy.

ペアになった観測の不確実性を測るために、データを各構成スクリプトの文字の直積から取られる要素を文字とするスクリプトとしてモデル化し、その結合エントロピーを計算した。

意味（1）

(information theory) The Shannon entropy of a "script" whose "characters" are elements of the Cartesian product of the sets of characters of the component scripts.

If random variables X and Y are mutually independent, then their joint entropy H(X,Y) is just the sum H(X)+H(Y) of its component entropies. If they are not mutually independent, then their joint entropy will be H(X)+H(Y)-I(X;Y) where I(X;Y) is the mutual information of X and Y.
