Researchers have identified a new condition, termed the 'self-approaching condition,' which is crucial for reliable short-horizon planning in world models. This condition addresses the issue where the latent distance to a goal might incorrectly rank candidate action sequences, even when they represent genuine progress. The study demonstrates that sharp bends in the latent space can create regions where this ordering reversal occurs, impacting planning accuracy. Experiments validate these predictions, suggesting that the arrangement of latent dimensions, rather than just their quantity, plays a significant role in planning performance. AI
