A rough set-based effective rule generation method for classification with an application in intrusion detection

Abstract: In this paper, we use Rough Set Theory (RST) to address the important problem of generating decision rules for data mining. In particular, we propose a rough set-based approach to mine rules from inconsistent data. It computes the lower and upper approximations for each concept, and then builds concise classification rules for each concept satisfying required classification accuracy. Estimating lower and upper approximations substantially reduces the computational complexity of the algorithm. We use UCI ML Repository data sets to test and validate the approach. We also use our approach on network intrusion data sets captured using our local network from network flows. The results show that our approach produces effective and minimal rules and provides satisfactory accuracy.

Challenges for future intelligent systems in biomedicine

ABSTRACT This special issue is an example of recent proposals to bring together and exchange AI initiatives that address both medical and biological issues and problems that need innovative solutions. Similar collaborative efforts are being launched by international institutions,such as the European Commission – e.g., via the BIOINFOMED project – and US organizations such as the American Medical Informatics Associations and the American College of Medical Informatics
