EXODUS: Stable and Efficient Training of Spiking Neural Networks

1 code implementation20 May 2022 Felix Christian Bauer, Gregor Lenz, Saeid Haghighatshoar, Sadique Sheik

In this paper, (i) we modify SLAYER and design an algorithm called EXODUS, that accounts for the neuron reset mechanism and applies the Implicit Function Theorem (IFT) to calculate the correct gradients (equivalent to those computed by BPTT), (ii) we eliminate the need for ad-hoc scaling of gradients, thus, reducing the training complexity tremendously, (iii) we demonstrate, via computer simulations, that EXODUS is numerically stable and achieves a comparable or better performance than SLAYER especially in various tasks with SNNs that rely on temporal features.

A Framework for Event-based Computer Vision on a Mobile Device

1 code implementation13 May 2022 Gregor Lenz, Serge Picaud, Sio-Hoi Ieng

We present the first publicly available Android framework to stream data from an event camera directly to a mobile phone.

A sampling-based approach for efficient clustering in large datasets

1 code implementation CVPR 2022 Georgios Exarchakis, Omar Oubari, Gregor Lenz

We propose a simple and efficient clustering method for high-dimensional data with a large number of clusters.

Adversarial Attacks on Spiking Convolutional Networks for Event-based Vision

no code implementations6 Oct 2021 Julian Büchel, Gregor Lenz, Yalun Hu, Sadique Sheik, Martino Sorbaro

Spiking neural networks work well with the sparse nature of event-based data and suit deployment on low-power neuromorphic hardware.

Event-based Face Detection and Tracking in the Blink of an Eye

no code implementations27 Mar 2018 Gregor Lenz, Sio-Hoi Ieng, Ryad Benosman

We will rely on a new feature that has never been used for such a task that relies on detecting eye blinks.
