probability n. 1.或有;或然性。 2.【哲學(xué)】蓋然性〔在 certainly 和 doubt 或 posibility 之間〕。 3.【數(shù)學(xué)】幾率,概率,或然率。 4.或有的事;可能的結(jié)果。 5.〔pl.〕〔美俚〕天氣預(yù)測(cè)。 What are the probabilities 有幾分把握? The probabilities are against us [in our favour]. 趨勢(shì)對(duì)我們好像不利[有利]。 hit probability 命中率。 in all probability 很可能,大概,多半,十之八九。 probability of (missile survival) (飛彈不被擊落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半會(huì)。 There is no probability of [that] ... 很難有,很難會(huì)。
Then , based on the study of bayesian network ( bn ) theory , the modeling method and flow of constructing bn based on expert knowledge is brought forward . also , with the study of probability propagation in trees of cluster ( pptc ) algorithm , a new diagnosing decision making method based on possibility - cost rate is given 在詳細(xì)研究了貝葉斯網(wǎng)絡(luò)理論的基礎(chǔ)上,提出了根據(jù)專家知識(shí)直接構(gòu)建貝葉斯網(wǎng)絡(luò)的建模方法和流程,并對(duì)團(tuán)數(shù)傳播算法進(jìn)行了細(xì)致的研究,引入了由概率代價(jià)比作為判斷故障節(jié)點(diǎn)順序的診斷決策算法。
