Thomas Gilles, Stefano Sabatini, Dzmitry Tsishkou, Bogdan, Stanciulescu, Fabien Moutarde

TL;DR
GOHOME introduces a graph-based heatmap approach for future motion prediction that improves accuracy, reduces computational load, and effectively models multimodal uncertainties in traffic scenes.
Contribution
It presents a novel graph-oriented model that generates heatmap outputs for agent trajectories, outperforming existing methods in speed and memory efficiency while maintaining state-of-the-art accuracy.
Findings
Achieves 2nd place on Argoverse Motion Forecasting Benchmark MissRate6.
Improves MissRate6 by over 15% with ensemble methods.
Demonstrates state-of-the-art results on nuScenes and Interaction datasets.
Abstract
In this paper, we propose GOHOME, a method leveraging graph representations of the High Definition Map and sparse projections to generate a heatmap output representing the future position probability distribution for a given agent in a traffic scene. This heatmap output yields an unconstrained 2D grid representation of agent future possible locations, allowing inherent multimodality and a measure of the uncertainty of the prediction. Our graph-oriented model avoids the high computation burden of representing the surrounding context as squared images and processing it with classical CNNs, but focuses instead only on the most probable lanes where the agent could end up in the immediate future. GOHOME reaches 2 on Argoverse Motion Forecasting Benchmark on the MissRate metric while achieving significant speed-up and memory burden diminution compared to Argoverse 1 place…
