An independent reproduction of the LeWorldModel research paper found that the evaluation protocol significantly influenced the reported results. The researchers achieved a higher success rate on the TwoRoom environment by implementing specific conventions not detailed in the original configuration files, such as dense action gathering and ImageNet pixel normalization. Furthermore, the study revealed that one-step prediction accuracy does not reliably predict long-horizon planning success, and batch normalization layers can inflate validation loss, masking flat training loss.
