Brain-Inspired Spatiotemporal Processing Algorithms for Efficient Event-Based Perception

Neuromorphic event-based cameras can unlock the true potential of bio-plausible sensing systems that mimic our human perception. However, efficient spatiotemporal processing algorithms must enable their low-power, low-latency, real-world application. In this talk, we highlight our recent efforts in this direction. Specifically, we talk about how brain-inspired algorithms such as spiking neural networks (SNNs) can approximate spatiotemporal sequences efficiently without requiring complex recurrent structures. Next, we discuss their event-driven formulation for training and inference that can achieve realtime throughput on existing commercial hardware. We also show how a brain-inspired recurrent SNN can be modeled to perform on event-camera data. Finally, we will talk about the potential application of associative memory structures to efficiently build representation for event-based perception.
