Patent ID: 8229875

Claim:
A method of performing data analysis processing in a computer system comprising a processor operable to execute computer program instructions, a memory operable to store computer program instructions executable by the processor, and computer program instructions stored in the memory and executable to perform the data analysis processing comprising: constructing a fuzzy likelihood by modeling a likelihood of data given a training class using fuzzy sets; and transforming the fuzzy likelihood into a probability distribution using a possibility-probability transformation, wherein the fuzzy likelihood is constructed by analyzing class data by estimating a degree of membership of the class data by: determining the data prototype, x p , to be an average of a collection of a single class; and determining the degree of membership according to: μ ⁡ ( x i ) = 1 - ⅆ ( x i - x p ) ⅆ ( x f - x p ) max i ⁢ { ⅆ ( x i - x p ) } , wherein x f is a farthest data from the prototype, in the class, and x i is an ith data point in the class.
