New research highlights limitations in latent space models' uncertainty quantification

A new paper titled "Biased Dreams" reveals significant limitations in how latent space models quantify epistemic uncertainty. Researchers found that these models, particularly the Recurrent State Space Model used in the Dreamer family, exhibit attractor behavior. This bias can cause discrepancies in environment dynamics to go unnoticed in latent space, undermining the reliability of uncertainty estimates and leading to overestimations of predicted rewards.
