InDRiVE: Reward-Free World-Model Pretraining for Autonomous Driving via Latent Disagreement
TLDR
InDRiVE uses latent disagreement for reward-free world-model pretraining in autonomous driving, enabling zero-shot and few-shot adaptation in CARLA.
Reasoning
The paper presents a novel reward-free pretraining method using latent ensemble disagreement as intrinsic motivation, which is a strength for reducing reward engineering. However, it is only evaluated in the CARLA simulator, lacking real-world validation, and the approach is specific to autonomous driving.

Methodology
The paper presents InDRiVE, a DreamerV3-style model-based reinforcement learning agent that performs reward-free pretraining in the CARLA simulator using intrinsic motivation derived from latent ensemble disagreement. Disagreement acts as a proxy for epistemic uncertainty, driving the agent toward under-explored driving situations. An imagination-based actor-critic learns a planner-free exploration policy directly from the learned world model. After pretraining, zero-shot transfer is evaluated by freezing all parameters and deploying the policy in unseen towns and routes, followed by few-shot adaptation using limited extrinsic feedback for lane following and collision avoidance.
Key Results
Disagreement-based pretraining yields stronger zero-shot robustness and robust few-shot collision avoidance under town shift and matched interaction budgets in CARLA experiments across towns, routes, and traffic densities.
