Researchers have developed Neural-Bayesian Structure Learning (Neural-BSL), a novel framework that integrates differentiable structure learning with discrete choice modeling. This approach estimates models from observational data by creating a single differentiable procedure that jointly learns attribute structure and random-utility parameters. Neural-BSL uses the learned structure to propagate interventions through downstream attributes, enabling predictions of mode-share responses and adjustments in traveler or trip attributes. Evaluations using stated-preference data from Seoul and revealed-preference data from London show that Neural-BSL achieves performance comparable to conventional benchmarks while uncovering behaviorally coherent dependency structures.
