Grzymala-Busse, J. Stefanowski and W. Ziarko, Informatica, this volume, which is in turn the response to the paper (Kononenko and Zorc, 1994). I clarify some points from our original paper that were mistakenly interpreted by Grzymala-Busse et al. and stress points from our original paper that were ignored by Grzymala-Busse et al. I conclude that with additions to the Rough Sets theory one can achieve good performance, which is however not due to Rough Sets but due to the additions, and that the use of Rough Sets is an unnecessary burden for machine learning algorithms. rv:
