prior probability

基本解释

Secondly, it is unneeded to obtain the prior probability in course of rough sets theory application.
而且，应用粗糙集理论不需要事先确定事件的先验概率。
First, the occurrence of all the system states is considered to have an equal possibility and for each component in the diagnosis system set a prior probability.
该模型首先假设系统的所有状态都是可能发生的，并对系统中的各个元件设定一个先验概率。
It collects information by market investigation, amends the prior probability, and consequently increases assurance of the investor on future success, so that the risk of decision-making is reduced.
它通过市场调查增加信息量，对先验概率进行修正，从而提高决策者对未来可能性的把握，达到降低决策风险的目的。

Unlike in prior quarters, there is not a high probability scenario that can be laid out with any degree of confidence ahead of earnings.

Such disaster, prior to the initial movement of the masses would have had probability of one-in-a-million.

the probability assigned to a parameter or to an event in advance of any empirical evidence, often subjectively or on the assumption of the principle of indifference &rarrcompare posterior probability

先验概率
The C4.5 method used information entropy to build the classification model without assuming prior probability was stable.
C4.5决策树方法利用信息熵来构建分类模型,无须假设先验概率的稳定。
