  5. Comparing with non - bnyain methods, it ' s prominent featares lay in that it combines the prior and posterior information, which avoids the disadvantag of subjective bias caused by simply using the prior information only, of blind search caused by the incomplete sample information, of noise affection caused by simply using the sample information only if we choice a suitable priof, we can conduct the bayesian leaming effectively, so it fits the problems of data mining and machine leaming that possess charaters of probability and statistics, especially when the samples are rare

    與非貝葉揚方法相比，貝葉斯方法的特出特點是其學習機制可以綜合先驗信息和后驗信息，既可避免只使用先驗信息可能帶來的主觀偏見，和缺乏樣本信息時的大量盲目搜索與計算，也可避免只使用樣本信息帶來的噪音的影響只要合理地確定先驗，就可以進行有效的學習。因此，適用於具有概率統計特徵的數據採掘和機器學習（或發現）問題，尤其是樣本難得的問題
  6. The sound quality of the appliance has become a significant component in the purchaser ' s overall subjective evaluation. the sound of the appliance used to be evaluated by the noise level measured in db ( a ). however, in some cases, the noise level measured in db ( a ) ca n ' t match the feeling of people

    根據有關國家標準，家用電器的噪聲通常採用a計權進行測量，但在某些情況下應用a計權測量的結果有可能不夠確切：在一些情況下，某些產品a聲級並不高，用戶卻抱怨噪聲太吵；而在另一些情況下，盡管其a聲級比較高，但用戶卻可以接受。
  7. Based on the principle of fuzzy analytic hierarchy process ( ahp ), judging matrices were constructed for quantitative calculating the membership of each subjective annoyance expression grade, in view of different environmental function districts, then corresponding environmental fuzzy membership functions were given, and applied to calculate the noise threshold of subjective annoyance response
