Topological solution of missing attribute values problem in incomplete information tables
In this paper, we present a method of data decomposition to avoid the necessity of reasoning on data with missing attribute values. We defined a general binary relation on the original incomplete data which decomposed into data subsets without missing values. Next, topological base relation method for classifier induction is applied to such sets. New approach to find the missing values in consi...
متن کاملA BAYESIAN APPROACH TO COMPUTING MISSING REGRESSOR VALUES
In this article, Lindley's measure of average information is used to measure the information contained in incomplete observations on the vector of unknown regression coefficients [9]. This measure of information may be used to compute the missing regressor values.
متن کاملIncomplete Databases: Missing Records and Missing Values
Data completeness is an essential aspect of data quality as in many scenarios it is crucial to guarantee the completeness of query answers. Data might be incomplete in two ways: records may be missing as a whole, or attribute values of a record may be absent, indicated by a null. We extend previous work by two of the authors [10] that dealt only with the first aspect, to cover both missing reco...
متن کاملRough Set Approach to Incomplete Information Systems
In the paper we present Rough Set approach to reasoning in incomplete information systems. We propose reduction of knowledge that eliminates only that information, which is not essential from the point of view of classification or decision making. In our approach we make only one assumption about unknown values: the real value of a missing attribute is one from the attribute domain. However, we...
