AEGNN: Asynchronous Event-based Graph Neural Networks

Abstract

The best performing learning algorithms devised for event cameras work by first converting events into dense representations that are then processed using standard CNNs. However, these steps discard both the sparsity and high temporal resolution of events, leading to high computational burden and latency. For this reason, recent works have adopted Graph Neural Networks (GNNs), which process events as “static” spatio-temporal graphs, which are inherently “sparse”. We take this trend one step further by introducing Asynchronous, Event-b Show more
