Abstract:

In order to overcome the incomplete inference mechanism and great computational complexity in FSSLMS algorithm , a new fuzzy LMS algorithm dominated by ELSE-action is presented. In the presence of an ELSE rule , the inference mechanism can be successfully executed with slight computational complexity in any input data conditions. As compared with other fuzzy LMS algorithms , the proposed algorithm is better because it constructs a simpler and more reliable fuzzy rule. Experimental results show that the proposed algorithm is of not only less computational complexity but also better perfonnances than other fuzzy LMS algorithms and other conventional LMS algorithms.
