Towards Non-Adversarial Algorithmic Recourse

no code implementations15 Mar 2024 Tobias Leemann, Martin Pawelczyk, Bardh Prenkaj, Gjergji Kasneci

We subsequently investigate how different components in the objective functions, e. g., the machine learning model or cost function used to measure distance, determine whether the outcome can be considered an adversarial example or not.

Multimodal Motion Conditioned Diffusion Model for Skeleton-based Video Anomaly Detection

1 code implementation ICCV 2023 Alessandro Flaborea, Luca Collorone, Guido D'Amely, Stefano D'arrigo, Bardh Prenkaj, Fabio Galasso

Leading OCC techniques constrain the latent representations of normal motions to limited volumes and detect as abnormal anything outside, which accounts satisfactorily for the openset'ness of anomalies.

Agnostic Visual Recommendation Systems: Open Challenges and Future Directions

no code implementations1 Feb 2023 Luca Podo, Bardh Prenkaj, Paola Velardi

Visualization Recommendation Systems (VRSs) are a novel and challenging field of study aiming to help generate insightful visualizations from data and support non-expert users in information discovery.

Are we certain it's anomalous?

1 code implementation16 Nov 2022 Alessandro Flaborea, Bardh Prenkaj, Bharti Munjal, Marco Aurelio Sterpa, Dario Aragona, Luca Podo, Fabio Galasso

By using uncertainty, HypAD may assess whether it is certain about the input signal but it fails to reconstruct it because this is anomalous; or whether the reconstruction error does not necessarily imply anomaly, as the model is uncertain, e. g. a complex but regular input signal.
