条件概率分布
查看英英释义
abstract:
In probability theory and statistics, given two jointly distributed random variables X and Y, the conditional probability distribution of Y given X is the probability distribution of Y when X is known to be a particular value; in some cases the conditional probabilities may be expressed as functions containing the unspecified value x of X as a parameter. The conditional distribution contrasts with the marginal distribution of a random variable, which is its distribution without reference to the value of the other variable.

网络释义
条件概率分布
... X 是 Y 的一个 父节点,表示 X 对 Y 有直接影响; ③每一个节点 Xi 都有一个条件概率分布(Conditional Probability Distribution , CPD) P( Xi | Parents ( Xi ) ) , 用于量化其父节点对该节点的影响, 对离散情况...
的条件概率分布
...对应的随机变量是二值的(真或者假),它们是离散的节点,因此可以将每个节点的条件概率分布(Conditional Probability Distribution,CPD)用表格的形式表示,这些表格称为CPT(Conditional Probability Table)。
