Optimal Feature Extraction for Multiclass Problems through Proper Choice of Initial Feature Vectors
초기 피춰벡터 설정을 통한 다중클래스 문제에 대한 최적 피춰 추출 기법
Abstract
In this Paper, we propose an optimal feature extraction for multiclass problems through proper choice of initial feature vectors. Although numerous feature extraction algorithms have been proposed, those algorithms are not optimal for multiclass problems. Recently, an optimal feature extraction algorithm for multiclass problems has been proposed, which provides a better performance than the conventional feature extraction algorithms. In this paper, we improve the algorithm by choosing good initial feature vectors. As a result, the searching time is significantly reduced. The chance to be stuck in a local minimum is also reduced.
