摘要:

针对Liu等(LIU J, MARTINEZ L, CALZADA A, et al. A novel belief rule base representation, generation and its inference methodology. Knowledge-Based Systems, 2013, 53: 129-141)提出的扩展置信规则库(BRB)推理精度不够高的问题,提出了一种改进的规则库构建与推理方法。在Liu等提出的规则库构建方法的基础上,给出了一种新的生成规则前件与计算规则权重的方法;同时为了避免大量不必要的规则被激活,引入80/20法则改进规则激活策略,并最终形成完整的置信规则库构建与推理方法。通过输油管道检漏的实例对所提方法的准确性和效率进行对比分析。实验结果表明,所提方法能够在保证低耗时的同时,将系统平均绝对误差(MAE)降低到0.17342,具有较高的效率和精度。

Abstract:

Considering the problem of the low inference accuracy of the extended Belief Rule Base (BRB) which was proposed by Liu, etc (LIU J, MARTINEZ L, CALZADA A, et al. A novel belief rule base representation, generation and its inference methodology. Knowledge-Based Systems, 2013, 53: 129-141), an improved method of rule-base construction and inference was proposed. This approach was based on the method of Liu's rule-base construction, and a new generation method of rule antecedents and a new calculation method of rule weights were provided. Subsequently, in order to avoid activating so many unnecessary rules, the 80/20 rule was introduced to improve the strategy of rule activation. Then an integrated construction and inference methodology of belief rule-base was formed. Finally, in order to validate the accuracy and efficiency of the new approach, the case study in pipeline leak detection was provided. The experimental results show that the proposed approach not only can keep lower time-consumption, but also can make the Mean Absolute Error (MAE) of system be reduced to 0.17342. This proves that the new approach has high accuracy and efficiency.
