초록

특징 선택 알고리즘들은 좋은 해를 찾기 위해 거대한 문제 공간을 폭넓게 효율적으로 탐색하여야 한다. 이 논문에서는 문제 공간의 적합도 지형을 통찰해보고자 하였으며, 알고리즘들의 탐색 능력을 개선하였다. 지역 최고값과 최저값에 대한 통계에 의해 해 공간을 조사한다. 또한 기존 알고리즘들의 동작을 분석하고 이들의 해를 개선하였다.

The feature selection algorithms should broadly and efficiently explore the huge problem spaces to find a good solution. This paper attempts to gain insights on the fitness landscape of the spaces and to improve search capability of the algorithms. We investigate the solution spaces in terms of statistics on local maxima and minima. We also analyze behaviors of the existing algorithms and improve their solutions.
