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).

The Intel Neuromorphic DNS Challenge

1 code implementation16 Mar 2023 Jonathan Timcheck, Sumit Bam Shrestha, Daniel Ben Dayan Rubin, Adam Kupryjanow, Garrick Orchard, Lukasz Pindor, Timothy Shea, Mike Davies

A critical enabler for progress in neuromorphic computing research is the ability to transparently evaluate different neuromorphic solutions on important tasks and to compare them to state-of-the-art conventional solutions.

Efficient Neuromorphic Signal Processing with Loihi 2

no code implementations5 Nov 2021 Garrick Orchard, E. Paxon Frady, Daniel Ben Dayan Rubin, Sophia Sanborn, Sumit Bam Shrestha, Friedrich T. Sommer, Mike Davies

The biologically inspired spiking neurons used in neuromorphic computing are nonlinear filters with dynamic state variables -- very different from the stateless neuron models used in deep learning.

e-TLD: Event-based Framework for Dynamic Object Tracking

1 code implementation2 Sep 2020 Bharath Ramesh, Shihao Zhang, Hong Yang, Andres Ussa, Matthew Ong, Garrick Orchard, Cheng Xiang

On the other hand, when the object re-enters the field-of-view of the camera, a data-driven, global sliding window detector locates the object for subsequent tracking.

Online Few-shot Gesture Learning on a Neuromorphic Processor

no code implementations3 Aug 2020 Kenneth Stewart, Garrick Orchard, Sumit Bam Shrestha, Emre Neftci

We present the Surrogate-gradient Online Error-triggered Learning (SOEL) system for online few-shot learning on neuromorphic processors.

On-chip Few-shot Learning with Surrogate Gradient Descent on a Neuromorphic Processor

no code implementations11 Oct 2019 Kenneth Stewart, Garrick Orchard, Sumit Bam Shrestha, Emre Neftci

Recent work suggests that synaptic plasticity dynamics in biological models of neurons and neuromorphic hardware are compatible with gradient-based learning (Neftci et al., 2019).

PCA-RECT: An Energy-efficient Object Detection Approach for Event Cameras

no code implementations24 Apr 2019 Bharath Ramesh, Andres Ussa, Luca Della Vedova, Hong Yang, Garrick Orchard

We present the first purely event-based, energy-efficient approach for object detection and categorization using an event camera.

Event-based Vision: A Survey

1 code implementation17 Apr 2019 Guillermo Gallego, Tobi Delbruck, Garrick Orchard, Chiara Bartolozzi, Brian Taba, Andrea Censi, Stefan Leutenegger, Andrew Davison, Joerg Conradt, Kostas Daniilidis, Davide Scaramuzza

Event cameras offer attractive properties compared to traditional cameras: high temporal resolution (in the order of microseconds), very high dynamic range (140 dB vs. 60 dB), low power consumption, and high pixel bandwidth (on the order of kHz) resulting in reduced motion blur.

Configuring deep Spiking Neural Networks (SNNs) is an exciting research avenue for low power spike event based computation.

DART: Distribution Aware Retinal Transform for Event-based Cameras

no code implementations30 Oct 2017 Bharath Ramesh, Hong Yang, Garrick Orchard, Ngoc Anh Le Thi, Shihao Zhang, Cheng Xiang

We introduce a generic visual descriptor, termed as distribution aware retinal transform (DART), that encodes the structural context using log-polar grids for event cameras.

HFirst: A Temporal Approach to Object Recognition

no code implementations5 Aug 2015 Garrick Orchard, Cedric Meyer, Ralph Etienne-Cummings, Christoph Posch, Nitish Thakor, Ryad Benosman

The asynchronous nature of these systems frees computation and communication from the rigid predetermined timing enforced by system clocks in conventional systems.
