Decision-forest voting scheme for classification of rare classes in network intrusion detection

no code implementations25 Jul 2021 Jan Brabec, Lukas Machlica

The algorithm leverages out-of-bag datasets to estimate prediction errors of individual trees, which are then used in accordance with the Bayes rule to refine the decision of the ensemble.

Joint Detection of Malicious Domains and Infected Clients

no code implementations21 Jun 2019 Paul Prasse, Rene Knaebel, Lukas Machlica, Tomas Pevny, Tobias Scheffer

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.
