Counteracting Concept Drift by Learning with Future Malware Predictions

no code implementations14 Apr 2024 Branislav Bosansky, Lada Hospodkova, Michal Najman, Maria Rigaki, Elnaz Babayeva, Viliam Lisy

We use GANs to learn changes in data distributions within different time periods of training data and then apply these changes to generate samples that could be in testing data.

Discovering Imperfectly Observable Adversarial Actions using Anomaly Detection

no code implementations22 Apr 2020 Olga Petrova, Karel Durkota, Galina Alperovich, Karel Horak, Michal Najman, Branislav Bosansky, Viliam Lisy

Experiments show that both algorithms are applicable for cases with low feature space dimensions but the learning-based method produces less exploitable strategies and it is scalable to higher dimensions.
