An Efficient Fuzzy Rough Approach for Feature Selection deal with the continuous values. However, the cost of computation of the approach is too high to be worked out as the number of selected features increases. In this paper, a new computational method is proposed to approximate the conditional mutual information between the selected features and the

We argue that Pawlak three-step approach for data analysis indeed uses both partitions and coverings for a complete information table. A slightly different formulation of Pawlak approach is given based on

Mining Incomplete Data—A Rough Set Approacheralization of the elementary set well-known in rough set theory, may be computed using such blocks. For incomplete data sets three different types of global approximations: singleton, subset and concept are defined. Additionally, for incomplete data sets a local approximation is defined as well.

Applications of Approximate Reducts to the Feature Selection Problem We also propose a new algorithm, called Rough Attribute Ranker. In our approach, the usefulness of features is measured by their impact on quality of the reducts that contain them. We experimentally compare the reduct-based methods with several classic attribute rankers using synthetic, as well as real-life high dimensional datasets.
