A Comparative Study of Graph Neural Network Layer Selection for Interaction Modelling in Driving Trajectory Prediction
A new research paper explores the effectiveness of various Graph Neural Network (GNN) layers for predicting driving trajectories. The study compares 19 different graph layer types, identifying five combinations that consistently outperform others, particularly ARMA, Chebyshev, and topology-aware layers. Key findings suggest that sum-based aggregation, multi-head attention, and weighted hop distances enhance prediction accuracy, offering practical design principles for future autonomous driving systems.
