Normal Cloud Distribution probability density fast calculation
Jingfang Wang · 2013
Normal cloud model with certainty, uncertainty and change into the stable characteristics in the expression of the knowledge, reflects the basic principle of the nature of species evolution, intelligent control, fuzzy evaluation, and other fields has been applied; Normal cloud distribution of the probability density is not an explicit expression, and is a special function integral to its in-depth application difficult; A fast calculating method of normal cloud distribution probability density is designed.According to the distribution characteristics, the sampling point on the logarithmic span is first designed , the second is to use the golden section principle to select the sample points before and after the interval; the method has been applied to the mixed-normal cloud model, the voice model, the effect is very good effect.
