Intrinsic Biologically Plausible Adversarial Training

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.

Online Spatio-Temporal Learning with Target Projection

no code implementations11 Apr 2023 Thomas Ortner, Lorenzo Pes, Joris Gentinetta, Charlotte Frenkel, Angeliki Pantazi

Recurrent neural networks trained with the backpropagation through time (BPTT) algorithm have led to astounding successes in various temporal tasks.

Dynamic Event-based Optical Identification and Communication

no code implementations13 Mar 2023 Axel von Arnim, Jules Lecomte, Naima Elosegui Borras, Stanislaw Wozniak, Angeliki Pantazi

Temporal pattern recognition, depending on the technology, involves a trade-off between communication frequency, range and accurate tracking.

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.
