摘要：
Feature selection is an important issue in pattern classification. In the present study, we develop a fast orthogonal forward selection (FOFS) algorithm for feature subset selection. The FOFS algorithm employs orthogonal transform to decompose correlations among candidate features, but it performs the orthogonal decomposition in an implicit way. Consequently, the fast algorithm demands less computational efforts as compared with the conventional orthogonal forward selection (OFS).
