Figureure 2 · : Preliminary evidence of action inconsistencyFigure 2: Preliminary evidence of action inconsistency. (a) Repeated stochastic rollouts from the same initial observation and identical action sequence exhibit divergent motion. (b) Controlled probes reveal violations of identity, inverse consistency, and compatibility, manifested as zero-action drift, incomplete inverse recovery, and endpoint mismatch under equivalent action decompositions.这张图来自论文 PDF 的结构化抽取。当前用于辅助理解 World Models as Group Actions 的方法或实验，请结合正文精读段落一起看。Figureure 4 · : Qualitative results for Group-Action Consistency (GAC) and Group-ActFigure 4: Qualitative results for Group-Action Consistency (GAC) and Group-Action Robustness (GAR). (a) Representative examples of identity, inverse, and compatibility probes, where GA regularization improves local action consistency. (b) Repeated stochastic rollouts from the same initial observation and identical action sequence. Although visual appearance varies across samples, the GA-regularized model exhibits more consistent motion evolution.这张图/表用于判断 World Models as Group Actions 的实验收益来自哪里。重点看替换、消融或跨模型设置下趋势是否一致，而不是只看单个最高分。
