초록

서포트 벡터 기계(Support Vector Machines, SVMs) 알고리즘은 표본 점들과 분리 초평면 사이의 최소 거리를 최대화하는 것에 관심을 가져왔다. 본 논문은 모든 데이터 점들과 분리 초평면 사이의 거리들을 고려하는 total margin을 제안한다. 본 논문에서 제안하는 방법은 기존의 서포트 벡터 기계 알고리즘을 확장하고, 일반화 오차 경계를 개선하게 된다. 새롭게 제안하는 total margin알고리즘이 기존 방법들과의 비교를 통하여 더욱 우수한 수행능력을 가지고 있음을 수치 예제들을 통하여 확인할 수 있다.

The Support Vector Machine(SVM) algorithm has paid attention on maximizing the shortest distance between sample points and discrimination hyperplane. This paper suggests the total margin algorithm which considers the distance between all data points and the separating hyperplane. The method extends existing support vector machine algorithm. In addition, this newly proposed method improves the generalization error bound. Numerical experiments show that the total margin algorithm provides good performance, comparing with the previous methods.
