置信区间估计(confidence interval estimate):利用估计的回归方程,对于自变量 x 的一个给定值 x0 ,求出因变量 y 的平均值的估计区间; 预测区间估计
为了解决这一问题,我们提出了一个新的置信度感知(confidence-aware)知识表示学习框架(CKRL),该框架在识别KGs中可能存在的噪声的同时进行有置信度的知识表示学习。

(A=>B)= number of A and B/number of A,confidence(A=>B)! = confidence(B=>A) 3.lift(A=>B)= confidence(A=>B)/support(B),lift(A=>B)= lift(B=>A) 对三个准则的解释: support confidence越高越好,一个高的confidence证明当交易出现了某个antecedent的时候,很大可能会出现某个consequent,也就是某条规则成立的概率越大。 假如confidence(A=>B)=80%,表明如果顾客购买了A,有80%的顾客同时有购买了B。 然而lift只有confidence(A=>B)/support(B)= 80% / 95% =0.8421,也就是说lift不太支持这条规则成立,因为顾客普遍都会买B,导致了support和confidence

关于上图中圈出的“Confidence Interval Formula”,有以下几种选择: ? 不同选择方式会带来不同的结果,但总体上相差不大: ? ? ? ? ? 算法选择: proportions——confidence interval——confidence intervals for one proportion 或 confidence intervals ——proportions——confidence intervals for one proportion 2. 【连续校正的二项式的正态近似法】 注:help文档中并未对上述几种公式的适用情况做详尽的说明,关于如何选择合适的confidence interval formula,欢迎大家留言讨论! interval type: two sided(双尾) confidence level: 1-α confidence interval width(two sided):置信区间宽度,即置信区间上限与下限之差
The confidence should be a decimal number between 0 and 1, with 0 being the lowest confidence and 1 being the highest confidence. The confidence should be a decimal number between 0 and 1, with 0 being the lowest confidence and 1 being the highest confidence. the highest confidence.
