Re-granulating a fuzzy rulebase
Scott Dick, A. Schencker, Mark Last, Horst Bunke, Abraham Kandel · 2002
We describe a computing-with-words algorithm for changing the granularity of an existing rulebase. A fuzzy rulebase is regranulated by manually selecting the granularity of each input dimension, and then automatically calculating the rulebase consequents. We demonstrate this algorithm by studying the common "fuzzy-PD" rulebase at various granularities. We find evidence that the "3/spl times/3" fuzzy-PD rulebase may be too coarse a granularity for this problem.
