Ultra-low-power Image Classification on Neuromorphic Hardware

1 code implementation28 Sep 2023 Gregor Lenz, Garrick Orchard, Sadique Sheik

We propose a temporal ANN-to-SNN conversion method, which we call Quartz, that is based on the time to first spike (TTFS).

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.

Membrane-Dependent Neuromorphic Learning Rule for Unsupervised Spike Pattern Detection

no code implementations5 Jan 2017 Sadique Sheik, Somnath Paul, Charles Augustine, Gert Cauwenberghs

Several learning rules for synaptic plasticity, that depend on either spike timing or internal state variables, have been proposed in the past imparting varying computational capabilities to Spiking Neural Networks.

Forward Table-Based Presynaptic Event-Triggered Spike-Timing-Dependent Plasticity

no code implementations11 Jul 2016 Bruno U. Pedroni, Sadique Sheik, Siddharth Joshi, Georgios Detorakis, Somnath Paul, Charles Augustine, Emre Neftci, Gert Cauwenberghs

We present a novel method for realizing both causal and acausal weight updates using only forward lookup access of the synaptic connectivity table, permitting memory-efficient implementation.
