Towards Chip-in-the-loop Spiking Neural Network Training via Metropolis-Hastings Sampling

no code implementations9 Feb 2024 Ali Safa, Vikrant Jaltare, Samira Sebt, Kameron Gano, Johannes Leugering, Georges Gielen, Gert Cauwenberghs

Our results show that the proposed approach strongly outperforms the use of backprop by up to $27\%$ higher accuracy when subject to strong hardware non-idealities.

Active Inference in Hebbian Learning Networks

no code implementations8 Jun 2023 Ali Safa, Tim Verbelen, Lars Keuninckx, Ilja Ocket, André Bourdoux, Francky Catthoor, Georges Gielen, Gert Cauwenberghs

This work studies how brain-inspired neural ensembles equipped with local Hebbian plasticity can perform active inference (AIF) in order to control dynamical agents.

Fusing Event-based Camera and Radar for SLAM Using Spiking Neural Networks with Continual STDP Learning

no code implementations9 Oct 2022 Ali Safa, Tim Verbelen, Ilja Ocket, André Bourdoux, Hichem Sahli, Francky Catthoor, Georges Gielen

This work proposes a first-of-its-kind SLAM architecture fusing an event-based camera and a Frequency Modulated Continuous Wave (FMCW) radar for drone navigation.

Continuously Learning to Detect People on the Fly: A Bio-inspired Visual System for Drones

no code implementations16 Feb 2022 Ali Safa, Ilja Ocket, André Bourdoux, Hichem Sahli, Francky Catthoor, Georges Gielen

This paper demonstrates for the first time that a biologically-plausible spiking neural network (SNN) equipped with Spike-Timing-Dependent Plasticity (STDP) can continuously learn to detect walking people on the fly using retina-inspired, event-based cameras.

A New Look at Spike-Timing-Dependent Plasticity Networks for Spatio-Temporal Feature Learning

no code implementations1 Nov 2021 Ali Safa, Ilja Ocket, André Bourdoux, Hichem Sahli, Francky Catthoor, Georges Gielen

We present new theoretical foundations for unsupervised Spike-Timing-Dependent Plasticity (STDP) learning in spiking neural networks (SNNs).
