Granular-Ball Fuzzy Set and Its Implementation in SVM 2023
Granular-ball definition center and radius:
Traditional fuzzy data processing structure with points as input can be converted to a new structure incorporating granular-ball fuzzy set
Original fuzzy dataset D = {(x1, σ 1 \sigma1 σ1), (x2, σ 2 \sigma2 σ2),…,(xn, σ n \sigma{n} σn)}
Granular-ball fuzzy dataset G = {(GB1, σ G B 1 \sigma{GB_1} σGB1), (GB2, σ G B 2 \sigma{GB_2} σGB2),…,(GBl, σ G B l \sigma{GB_l} σGBl)}
l l l and σ G B l \sigma{GB_{l}} σGBl represent the number and membership degree of fuzzy granular-ball
Each granular-ball can be represented by its center c i c_i </
