A form of logic where truth values can be any real number between 0 and 1, used in computing and control systems to handle imprecise data.
The formal system of reasoning with degrees of truth
The standard technical term for fuzzy logic in Japanese. Used in academic and engineering contexts.
ファジー論理は制御システムに広く使われている。
Fuzzy logic is widely used in control systems.
An alternative spelling of 'fuzzy logic', sometimes seen in older or specific academic texts.
この論文ではファジィ論理を用いた推論を提案する。
This paper proposes reasoning using fuzzy logic.
The idea of reasoning that is not strictly true or false, often used metaphorically
Literally 'ambiguous logic'. Used to describe fuzzy logic in a more general, non-technical sense, or to explain the concept to non-experts.
人間の思考はあいまいな論理に基づいていることが多い。
Human thinking is often based on fuzzy logic.
A mix of the loanword 'fuzzy' and the Japanese word for logic. Less formal than ファジー論理, sometimes used in casual explanations.
ファジーな論理って、要するに白黒つけない考え方だよね。
Fuzzy logic is basically a way of thinking that doesn't force things into black and white, right?
In technical contexts (papers, presentations, engineering), always use ファジー論理. In everyday conversation when explaining the concept, あいまいな論理 is more natural. Avoid directly translating 'fuzzy' as けばけばしい or ぼやけた, as these refer to physical fuzziness, not logical imprecision.
