In this paper, Bayesian based aggregation of decision trees in an ensemble (decision forest) is investigated. The focus is laid on multi-class classification with number of samples significantly skewed toward one of the classes. The algorithm leverag

Many real-world classification problems are significantly class-imbalanced to detriment of the class of interest. The standard set of proper evaluation metrics is well-known but the usual assumption is that the test dataset imbalance equals the real-

Detection of malware-infected computers and detection of malicious web domains based on their encrypted HTTPS traffic are challenging problems, because only addresses, timestamps, and data volumes are observable. The detection problems are coupled, b

For research to go in the right direction, it is essential to be able to compare and quantify performance of different algorithms focused on the same problem. Choosing a suitable evaluation metric requires deep understanding of the pursued task along

This paper proposes a generic classification system designed to detect security threats based on the behavior of malware samples. The system relies on statistical features computed from proxy log fields to train detectors using a database of malware

Hydrologické modely sú nástrojmi, často využívanými pri riešení širokého spektra hydrologických problémov. Každý z modelov má svoju vlastnú štruktúru, definujúcu vzájomné vzťahy prvkov hydrologickej bilancie. Preto musí byť p

Despite being one of the smallest countries in the OECD, Israel is marked by significant socio-economic disparities, which have a clear spatial dimension. Ethnic and religious groups with weak socio-economic outcomes are not benefitting from the thri
