Discrete-WAM addresses a key limitation in autonomous driving by unifying world modeling and policy learning through aligned discrete tokens, enabling explicit causal reasoning over counterfactual futures. This approach moves beyond standard state-to-action correlations to support compositional generalization across diverse driving scenarios while maintaining competitive benchmark performance. The method offers a principled framework for generating controllable, reliable decision-making in complex environments.
Discrete-WAM: Unified Discrete Vision-Action Token Editing for World-Policy Learning
arXiv:2606.05645v1 Announce Type: new Abstract: Autonomous driving requires reasoning about how ego actions shape the evolution of the surrounding world. However, most end-to-end methods rely on direct state-to-action mappings, capturing correlations without explicitly modeling action-conditioned dynamics. Conversely, continuous-latent world models often lack compositional structure for causal reasoning across counterfactual futures. We introduce Discrete-WAM, a unified latent vision-action world policy that represents future visual states and ego actions as aligned discrete tokens, enabling compositional causal reasoning across alternative futures. Built upon this unified discrete alignment, Discrete-WAM establishes a shared discrete diffusion framework with unified generative tasks, jointly formulating world modeling, world-action policy, and hierarchical decision-enabled policy, supporting compositional generalization across diverse driving scenarios. Experiments on large-scale autonomous-driving benchmarks show that Discrete-WAM achieves competitive performance while supporting controllable generation and counterfactual reasoning, offering a principled path toward more reliable decision-making.
