Aiming at the uncertainty problem in the center point of the observation data, based on intuitive fuzzy clustering, it proposes a data association algorithm using the intuitive fuzzy entropy to improve weighting. The improved fuzzy C-means clustering (IFCM) algorithm is applied to the data correlation calculation. First intuitive fuzzy the observed data and the prediction data, second using Intuitive Fuzzy Entropy to improve the data weight of intuitive fuzzy sets, third caculating the weighted distances of intuitive fuzzy to obtain the membe...
