Core Reduct Based Preprocessing Approach to Incomplete Data

Abstract: Most of the data mining algorithm's application hampers due to missing attribute values. Inadequate treatment of missing values seriously affects the data mining and classification accuracy. A useful technique has been proposed to deal with missing attribute values. Rough set approach to incomplete information system has been shown. Application of discernible matrix for incomplete information to compute core and reduct has been shown. Imputation based preprocessing approach depends on relation between present … Show more

“…Rough set can deal with missing values efficiently. Concepts of indiscernibility relation and discernibility matrix of rough set is very popular to fill missing values [1]- [2]. Rough sets core and reduct concepts used to impute missing value using most similar object [1]- [2].…”
