Mind the GAP: Glimpse-based Active Perception improves generalization and sample efficiency of visual reasoning

no code implementations30 Sep 2024 Oleh Kolner, Thomas Ortner, Stanisław Woźniak, Angeliki Pantazi

Active vision theories postulate that the learning of visual relations is grounded in actions that we take to fixate objects and their parts by moving our eyes.

Intrinsic Biologically Plausible Adversarial Robustness

no code implementations29 Sep 2023 Matilde Tristany Farinha, Thomas Ortner, Giorgia Dellaferrera, Benjamin Grewe, Angeliki Pantazi

Artificial Neural Networks (ANNs) trained with Backpropagation (BP) excel in different daily tasks but have a dangerous vulnerability: inputs with small targeted perturbations, also known as adversarial samples, can drastically disrupt their performance.
