The Compound Operations of Uncertain Cloud Concepts
Cloud model, an effective new cognitive model, is used to simulate the bidirectional cognitive computing between the intension and extension of concept from the Forward Cloud Generator (FCG) and the Backward Cloud Generator (BCG). In this paper, two kinds of cloud concepts, i.e., young people and middle-aged are used to generate the compound concepts in Matlab. Firstly, the FCG is used for generating the extension set of a cloud concept. And the extension set of cloud concept can be obtained by the set operations, such as union operation, intersection operation, complementary operation and symmetric difference operation.
