Reducing the redundant attributes is an important preprocessing step in data mining. In the paper, a novel search algorithm COREplusAFSA for minimal attribute set reduction based on rough set theory and artificial fish swarm algorithm is proposed. Fi

The imbalanced data problem turned out to be one of the most important and challenging problems in artificial intelligence. We discuss an approach of minority class approximation based on rough set methods and three-way decision. This approach seems

We discuss an approach of concept approximation based on judgment rather than on partial containment of sets only. This approach seems to be much more general than the traditional one. However, it requires developing some new logical tools for reason

More than two decades ago the imbalanced data problem turned out to be one of the most important and challenging problems. Indeed, missing information about the minority class leads to a significant degradation in classifier performance. Moreover, co

Selective preprocessing, representing data–level approach to the imbalanced data problem, is one of the most successful methods. This paper introduces novel algorithm combining this kind of technique with the filtering phase. The information granul

Discretization of numerical (continuous) attributes is one of the most important data preprocessing tasks in knowledge discovery and data mining. Some of data mining techniques require discretized data. The article aim is to demonstrate that discreti
