A New Rough Sets Decision Method Based on PCA and Ordinal Regression

10/2008; DOI:10.1007/978-3-540-88425-5_36 pp.349-358

ABSTRACT The classical multivariate statistical method can only discuss the effectiveness of result, but can’t explain the cause and
intrinsic mechanism when dealing with classification problems. In this paper, a new rough sets decision method based on the
Principal Component Analysis (PCA) and the ordinal regression is proposed which may help to explain the cause and the intrinsic
mechanism of classification problems. An empirical study is employed to validate the reasonability and effectiveness of the
proposed method.
