초록

본 논문에서는 패턴인식의 정확성을 향상시키기 위한 지능시스템을 제안한다. 제안한 지능시스템은 신경회로망의 무감독학습 방법인 SOPM(Self Organizing Feature Map), LVQ(Learning Vector Quantization), 그리고 퍼지이론의 FCM(Fuzzy C-means)을 이용하여 구성한다. 제안한 지능시스템의 유용성은 실험을 통해 확인한다. 실험은 Fisher의 Iris 데이터 분류, Cambridge 대학의 Olivetti 연구실(ORL; Olivetti Research Laboratory)에서 제공하는 얼굴 데이터베이스를 이용한 얼굴 영상 데이터 분류, 그리고 근전도(EMG, Electromyogram) 데이터를 분류하는 것이다. 제안한 지능시스템은 일반적인 LVQ와 비교한다. 실험을 통해 제안한 지능시스템이 일반적인 LVQ보다 패턴 인식의 정확성이 더 우수함을 알 수가 있었다.

In this paper, we propose a intelligent system to improve the accuracy of pattern recognition. The proposed intelligent system consist in SOFM, LVQ and FCM algorithm. We are confirmed the effectiveness of the proposed intelligent system through the several experiments that classify Fisher's Iris data and face image data that offered by ORL of Cambridge Univ. and EMG data. As the results of experiments, the proposed intelligent system has better accuracy of pattern recognition than general LVQ.
