New theory challenges prediction error as sole metric for latent world models

A new paper proposes a control theory framework for latent world models, challenging the assumption that minimizing prediction error directly leads to better control. The research argues that planners operate off the data manifold, where prediction errors do not reliably correlate with control success. Instead, the paper introduces a 'discrepancy' metric between predicted and true plan-costs, demonstrating that this metric better bounds planner suboptimality and tracks control performance in experiments.
