SIFT and SURF based feature extraction for the anomaly detection

1 code implementation24 Mar 2022 Simon Bilik, Karel Horak

In this paper, we suggest a way, how to use SIFT and SURF algorithms to extract the image features for anomaly detection.

Feature space reduction as data preprocessing for the anomaly detection

1 code implementation13 Mar 2022 Simon Bilik, Karel Horak

We show that the convolutional autoencoder architecture doesn't have a significant effect for this task and we prove the potential of our approach on the real world dataset.

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.
