probability n. 1.或有;或然性。 2.【哲學】蓋然性〔在 certainly 和 doubt 或 posibility 之間〕。 3.【數學】幾率,概率,或然率。 4.或有的事;可能的結果。 5.〔pl.〕〔美俚〕天氣預測。 What are the probabilities 有幾分把握? The probabilities are against us [in our favour]. 趨勢對我們好像不利[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。 There is no probability of [that] ... 很難有,很難會。
6 . the basic principle of turbo equalization is discussed and the siso equalization algorithms based on a posteriori probability and interference cancellation are derived . at last , the simulation results are provided 6 .論述了turbo均衡的基本原理,推導了基于后驗概率和干擾消除的5150均衡算法,給出了性能仿真結果。
The main contributions are as follows : ( 1 ) de ( differential evolution ) algorithm is proposed to invert the ocean acoustic parameters in shallow water in order to get faster and more accurate results than ga ( genetic algorithm ) and sa ( simulated annealing algorithm ) . also a posteriori probability analysis method is applied to evaluate the uncertainty of inversion results . ( 2 ) maximum likelihood objective functions for broadband mfi are derived according to different conditions ( 2 )根據不同的前提條件,采用似然比的方法推導了寬帶匹配場反演的最大似然目標函數;深入地研究了寬帶匹配場處理中的相干與非相干問題;在分析參數反演的敏感性之后,提出了淺海環境參數寬帶匹配場反演的多步優化策略,并與全參數反演方法進行了性能上的仿真比較。
Among others , the probability analysis approach has difficulty in deciding objective probability , and thus it is necessary to obtain subjective probability through expert empirical prediction , modify it by the bayesian formula and get a posteriori probability , and substitute it for objective probability in risk measurement and risk premium calculation 其中,概率分析方法在應用中就存在客觀概率不易確定的難點問題,因此需用專家經驗預測法得到主觀概率后,利用貝葉斯公式加以修正并獲得后驗概率,再用后驗概率代替客觀概率進行風險的度量及風險收益的計算。
