A Novel Robust Fuzzy Rough Set Model for Feature Selection
Algorithm 1
Feature selection algorithm based on RS-FRS model with SPS.
| Input: a set of condition attributes ; a set of samples . | | Output: selected feature subset | (1) | , according to equation (5), the lower approximation of RS-FRS model is computed; | (2) | Compute every and ; | (3) | Sort according to ; | (4) | whiledo | (5) | Selected the first sample pair ; | (6) | Select one such that and add into ; | (7) | ; | (8) | end while | (9) | return |
