A fast geometric defuzzication operator for large scale information retrieval
Simon Coupland, David Croft, Stephen C. Brown · 2014
In this paper we explore the centroid defuzzification operation in the context of specific data retrieval application. We present a novel implication and centroid defuzzification approach based on geometric fuzzy sets and systems. It is demonstrated that this new approach requires fewer operations and results in a significant reduction in processing time in our application.
