QQWorld Uses Quantile-Quantile Matching for World Model Regularization
July 29, 2026
QQWorld addresses vanishing corrective gradients in latent world models by replacing the Epps-Pulley objective with quantile-quantile matching. This approach aligns projected latent samples with rank-matched Gaussian quantiles to maintain effective control over heavy-tailed deviations in the distribution.
