Researchers have identified a new failure mode in latent world models called "physical representation laziness," where learned latent states fail to capture crucial physical properties, leading to planning errors. To address this, they propose a "Fourier auxiliary head" that enforces physically-informed structuring of the latent space during training. This method significantly improves planning success rates, especially in dynamic environments and low-data regimes, without adding inference-time costs. AI
