Probabilistic Fuzzy Cognitive Maps Based on Ordered Weighted Averaging Operators
|
Abstract:
By aggregating the casual reasoning results with simple weighted sum,the Fuzzy Cognitive Maps (FCM) and the Probabilistic Fuzzy Cognitive Maps (PFCM) ignore the uncertainties of And/Or combinations among the antecedent nodes.The threshold functions cause further distortions to the inference results.A novel fuzzy cognitive model,Probabilistic Fuzzy Cognitive Maps based on Ordered Weighted Averaging (OWA) operators,OWA-PFCM was proposed by preserving the merits of FCM and PFCM,and introducing OWA operators fo...
