When Does Latent Reasoning Help? MeRa: Metric-Space Bias for Spatial Prediction

arXiv:2606.03727v1 Announce Type: new Abstract: Latent reasoning has improved sequential recommendation by iteratively refining representations before prediction, but does it help spatial prediction? We find that the answer depends on whether reasoning is grounded in the underlying metric space. Without such grounding, latent reasoning degrades spatial prediction below the unmodified baseline, while a learned metric-space bias derived from pairwise distances produces consistent gains.
