| 摘 要： | 为了更有效地表达和处理系统的不确定性,提出了基于多分辨率分析的区间类型2(简称多分辨率区间类型2)模糊系统,构造了多分辨率区间类型2隶属度函数,并给出了基于尺度函数分解的结构和参数学习算法.多分辨率区间类型2模糊系统的前件是多分辨率隶属度函数,后件是输入的线性函数,因此系统可以自适应地划分输入论域空间,优化系统结构.将多分辨率区间类型2模糊系统应用于带有噪声的时间序列预测,预测结果的复杂度较小,均方根误差为0.105 2.

| Abstract: | In order to effectively express and deal with the uncertainty of systems,an interval type-2 fuzzy logic system based on multi-resolution analysis was proposed,and a multi-resolution interval type-2 membership function was constructed.In addition,its structure and learning algorithm were given based on scaling function decomposition.The antecedent of the multi-resolution interval type-2 fuzzy system is a multi-resolution membership function,and the consequent is a linear function of inputs.As a result,the mu... |
