The transformation between fuzzy cognitive maps and a class of simplified dynamical cognitive networks

Cognitive Map (CM), Fuzzy Cognitive Map (FCM), and Dynamical Cognitive Network (DCN) are three related tools for modeling human being's cognition and facilitate machine inference accordingly. A main desirable feature of FCM is that it is easy to use for modeling and visualizing human knowledge. Different models in the CM family have different capabilities in capturing human knowledge. However, a recent theoretical result shows that a CM can be transformed into a FCM and vice versa. This paper reports that a class of simplified DCN can also be transformed into FCM.
