probability n. 1.或有;或然性。 2.【哲学】盖然性〔在 certainly 和 doubt 或 posibility 之间〕。 3.【数学】几率,概率,或然率。 4.或有的事;可能的结果。 5.〔pl.〕〔美俚〕天气预测。 What are the probabilities 有几分把握? The probabilities are against us [in our favour]. 趋势对我们好像不利[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) (飞弹不被击落的)概率。 The probability is that ... 大概是…,很可能是…。 There is every probability of [that] ... 多半有,多半会。 There is no probability of [that] ... 很难有,很难会。
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 .论述了turbo均衡的基本原理,推导了基于后验概率和干扰消除的5150均衡算法,给出了性能仿真结果。
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 )根据不同的前提条件,采用似然比的方法推导了宽带匹配场反演的最大似然目标函数;深入地研究了宽带匹配场处理中的相干与非相干问题;在分析参数反演的敏感性之后,提出了浅海环境参数宽带匹配场反演的多步优化策略,并与全参数反演方法进行了性能上的仿真比较。
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,概率分析方法在应用中就存在客观概率不易确定的难点问题,因此需用专家经验预测法得到主观概率后,利用贝叶斯公式加以修正并获得后验概率,再用后验概率代替客观概率进行风险的度量及风险收益的计算。
