Abstract

Finding the optimal parameter values for parameterized operators such as the S-OWA-AND aggregation operator or BADD defuzzification method can be difficult. Also, as the reasoning situation changes, the optimal parameter values may change. This paper first demonstrates how much the output of a given fuzzy system, one that controls an inverted pendulum, can vary depending on which aggregation operator and/or defuzzification method is used. These variations can be more significant than varying the rules or membership functions. Next, examples are given of how dynamic switching of parameterized operators can be used to determine appropriate parameter values as the reasoning situation changes. Our technique involves the dynamic generation of switching tables from which hierarchical meta-rules can be created. These meta-rules can then be used to dynamically change the appropriate parameter values as warranted.
动态参数化操作符的行为差异
为参数化操作符(如S-OWA-AND聚合操作符或BADD去模糊化方法)找到最优参数值可能很困难。此外,随着推理情况的变化,最优参数值也可能发生变化。本文首先证明了一个给定的模糊系统的输出,一个控制倒立摆的系统,可以根据使用的聚合算子和/或去模糊化方法而变化。这些变化可能比改变规则或成员函数更重要。其次,给出了随着推理情况的变化,如何利用参数化算子的动态切换来确定合适的参数值的实例。我们的技术涉及动态生成交换表,可以从中创建分层元规则。然后可以使用这些元规则动态地更改适当的参数值。
