Question

高手帮忙给翻译下吧，谢谢啦，不要用翻译器啊~

Normally, an arc in an influence diagram denotes an influence, i.e., the fact that the node at the tail of the arc influences the value (or the probability distribution over the possible values) of the node at the head of the arc. Some arcs in influence diagrams have clearly a causal meaning. In particular, a directed path from a decision node to a chance node means that the decision (i.e., a manipulation of the graph) will impact that chance node in the sense of changing its probability distribution.

一般情况下，影响图中的弧代表着关联（的关系），即弧的尾端的节点影响弧的头部的节点的值（或者可能值的概率分布）。关联图中的有些弧明显具有偶然性。特别是从一个决策节点指向一个机会节点的有向路径表明该决策（即该图的操作）会通过改变其概率分布来影响该节点。
