Abstract:

Some image features of the cloud model created by the forward cloud generator available contradict human cognition,which influences the accuracy of applications directly. For these contradictions, modifications to the forward cloud generator are made in this paper. A function for calculating the cognitive ambiguity value of each sample point in concept is given. Comparing two algorithms, simulation results show that the cloud model created by the modified forward cloud generator is capable of satisfying human cognition and can describe the natural concept more precisely.

Key words: cloud model, forward cloud generator, trust management, fuzzy logic, artificial Intelligence
