- W1978080609 abstract "본 논문에서는 학습기법을 사용하지 않고 패턴분류의 성능을 최대화하면서 규칙의 수를 줄일 수 있는 통계적 정보기반 계층적 퍼지-러프 분류방법을 제안한다. 제안된 방법에서 통계적 정보는 계층적 퍼지-러프 분류 시스템에서 각 계층의 입력부 퍼지집합의 분할 구간을 추출하기 위해서 사용되었고, 러프집합은 통계적 정보로부터 추출된 분할 구간들과 연관된 퍼지 if-then 규칙의 수를 최소화하기 위해서 사용되었다. 제안된 방법의 효과성을 보이기 위해 Fisher의 IRIS 데이터를 사용한 기존 패턴분류 방법의 분류 정확도와 규칙들의 수를 비교하였다. 그 결과, 제안된 방법은 기존 방법들의 분류 성능과 유사함을 확인할 수 있었다. In this paper, we propose a hierarchical fuzzy-rough classification method based on statistical information for maximizing the performance of pattern classification and reducing the number of rules without learning approaches such as neural network, genetic algorithm. In the proposed method, statistical information is used for extracting the partition intervals of antecedent fuzzy sets at each layer on hierarchical fuzzy-rough classification systems and rough sets are used for minimizing the number of fuzzy if-then rules which are associated with the partition intervals extracted by statistical information. To show the effectiveness of the proposed method, we compared the classification results(e.g. the classification accuracy and the number of rules) of the proposed with those of the conventional methods on the Fisher's IRIS data. From the experimental results, we can confirm the fact that the proposed method considers only statistical information of the given data is similar to the classification performance of the conventional methods." @default.
