Abstract :
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 "3×3" fuzzy-PD rulebase may be too coarse a granularity for this problem
