We present a way to implement long short-term memory (LSTM) cells on spiking neuromorphic hardware.
Event-Based Vision at the Edge
Neuromorphic event‐based vision sensors are poised to dramatically improve the latency, robustness and power in applications ranging from smart sensing to autonomous driving and assistive technologies for people who are blind.
Soon these sensors may power low vision aids and retinal implants, where the visual scene has to be processed quickly and efficiently before it is displayed. However, novel methods are needed to process the unconventional output of these sensors in order to unlock their potential.

Efficient multi-scale representation of visual objects using a biologically plausible spike-latency code and winner-take-all inhibition
We present a SNN model that uses spike-latency coding and winner-take-all inhibition to efficiently represent visual objects with as little as 15 spikes per neuron.

A GPU-accelerated cortical neural network model for visually guided robot navigation
We present a cortical neural network model for visually guided navigation that has been embodied on a physical robot exploring a real-world environment. The model includes a rate based motion energy model for area V1, and a spiking neural network model for cortical area MT. The model generates a cortical representation of optic flow, determines the …
