条件独立
喺概率论上,条件独立(英文:conditional independence)就系指一件事件唔会影响第件事件嘅条件概率,即系话如果
P ( A | B , C ) = P ( A | C ) {\displaystyle P(A|B,C)=P(A|C)} ,
噉 A {\displaystyle A} 同 B {\displaystyle B} 就算系"喺 C {\displaystyle C} 之下条件独立"(conditionally independent given C), ( A ⊥ ⊥ B | C ) {\displaystyle (A\perp \!\!\!\perp B|C)} [1].
