Decision-forest voting scheme for classification of rare classes in network intrusion detection
Jan Brabec, Lukas Machlica
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…
Learning Explainable Representations of Malware Behavior
Paul Prasse, Jan Brabec, Jan Kohout +3
We address the problems of identifying malware in network telemetry logs and providing \emph{indicators of compromise} -- comprehensible explanations of behavioral patterns that id…
On Model Evaluation under Non-constant Class Imbalance
Jan Brabec, Tomáš Komárek, Vojtěch Franc +1
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 th…
Bad practices in evaluation methodology relevant to class-imbalanced problems
Jan Brabec, Lukas Machlica
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 e…
