Разпознаването на размити модели е важна насока в изследването на теорията на размитите множества, а невронната мрежа е обичаен метод за заразяване с данни.

In1965,awell-knownAmericancyberneticexpertandprofessorattheUniversityofCaliforniaLAZadeh(1965)proposedtheconceptoffuzzysets,establishedthetheoryoffuzzysets,andcreatedAtheoreticalmethodtostudytheproblemofambiguityoruncertainty.Inthepast40years,fuzzytheoryandtechnologyhavedevelopedrapidly.Applieddisciplinesbasedonfuzzysettheory,suchasfuzzyclusteranalysis,fuzzypatternrecognition,fuzzycomprehensiveevaluation,fuzzydecisionandfuzzyprediction,fuzzyplanning,fuzzycontrol,fuzzyInformationprocessinghasplayedaveryimportantroleinindustry,agriculture,medicine,military,computerscience,informationscience,managementscience,systemscience,engineeringtechnologyandotherdisciplines,andhasbroughthugeeconomicbenefits.
В ежедневието, хората често използват усет за идентифициране на графики, текст, език и т.н., в областите на метеорологичните науки, инженерните изследвания, инженерството на околната среда, медицината, криминалните разследвания, военните и т.н. никой обект не принадлежи. Това е проблемът на разпознаването на шаблони.
