RetroMotion model forecasts agent motion with retrocausal transformers

Researchers have developed RetroMotion, a novel approach to motion forecasting for road users that decomposes complex joint trajectory predictions into simpler marginal and pairwise distributions. This method utilizes a transformer model with a retrocausal information flow, enabling it to generate more accurate predictions by considering later trajectory points to inform earlier ones. Notably, RetroMotion not only achieves state-of-the-art results on several benchmark datasets but also demonstrates an inherent ability to follow instructions, adapting forecasts based on contextual commands.
