New Alt-GNNs Integrate GEV Models and Deep Learning for Choice Modeling

Researchers have introduced Alternative Graph Neural Networks (Alt-GNNs), a novel approach that integrates generalized extreme value (GEV) models with deep learning for discrete choice modeling. This new framework embeds the dependence between choice alternatives directly within neural architectures, overcoming limitations of previous methods that required predefined or symmetric dependence structures. Alt-GNNs are theoretically consistent with random utility maximization and empirically demonstrate significant improvements in predictive performance on travel mode choice datasets. AI
