Researchers have introduced Temporal-Distance JEPA (TD-JEPA), a novel approach to representation learning for latent world model predictive control. This method enhances Joint-Embedding Predictive Architectures (JEPAs) by mining a directed temporal cost from reward-free trajectories, improving the ability to plan based on goal progress. TD-JEPA uses same-trajectory step order as positive targets and cross-trajectory pairs as heuristic negatives, alongside a rollout-consistency term. This approach aims to bridge the gap between training and planning in JEPA world models by uncovering temporal progress structures within offline logs. AI
IMPACT This research could improve the planning capabilities of AI systems by enabling them to better understand and predict future states from observational data.
