inference n. 1.推理,推論;推斷,結(jié)論,論斷;含蓄,含意。 2.推斷的結(jié)果;(邏輯上的)結(jié)論。 speak from inference 推測說。 draw [make] an inference from ... 根據(jù)…下結(jié)論。 the deductive [inductive] inference 演繹[歸納]推理。
Compared with the regular rule - based expert system , the bayesian network based es can reason on the incomplete input information using the prior probability distribution ; the topological structure of the network being used to express the qualitative knowledge and the probability distributions of the nodes in the network being used to express the uncertainty of the knowledge , which made the knowledge representation more intuitively and more clearly ; applying the principle of the bayesian chaining rule , bidirectional inference which allow infer from the cause to the effect and from the effect to the cause can be achieved 與一般基于規(guī)則的專家系統(tǒng)相比,貝葉斯網(wǎng)專家系統(tǒng)利用先驗概率分布,可以使推理在輸入數(shù)據(jù)不完備的基礎(chǔ)上進行;以網(wǎng)絡(luò)的拓撲結(jié)構(gòu)表達定性知識,以網(wǎng)絡(luò)節(jié)點的概率分布表達知識的不確定性,從而使不確定性知識的表達直觀、明確;利用貝葉斯法則的基本原理,可以實現(xiàn)由因到果及由果到因的雙向推理。
