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

1 code implementation30 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.

On the visual analytic intelligence of neural networks

no code implementations28 Sep 2022 Stanisław Woźniak, Hlynur Jónsson, Giovanni Cherubini, Angeliki Pantazi, Evangelos Eleftheriou

Visual oddity task was conceived as a universal ethnic-independent analytic intelligence test for humans.

Learning in Deep Neural Networks Using a Biologically Inspired Optimizer

no code implementations23 Apr 2021 Giorgia Dellaferrera, Stanislaw Wozniak, Giacomo Indiveri, Angeliki Pantazi, Evangelos Eleftheriou

Here, we propose a novel biologically inspired optimizer for artificial (ANNs) and spiking neural networks (SNNs) that incorporates key principles of synaptic integration observed in dendrites of cortical neurons: GRAPES (Group Responsibility for Adjusting the Propagation of Error Signals).

Online Spatio-Temporal Learning in Deep Neural Networks

1 code implementation24 Jul 2020 Thomas Bohnstingl, Stanisław Woźniak, Wolfgang Maass, Angeliki Pantazi, Evangelos Eleftheriou

For shallow networks, OSTL is gradient-equivalent to BPTT enabling for the first time online training of SNNs with BPTT-equivalent gradients.
