Figureure 5 · : Comparison of VAR with/without semantic guidanceFig. 5: Comparison of VAR with/without semantic guidance. We conduct a comprehensive evaluation of generation performance for models trained with and without semantic guidance. All the models are dense transformers without MoE layers.这张图/表用于判断 MEPA 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。Figureure 2 · : An overview of our proposed MEPA frameworkFig. 2: An overview of our proposed MEPA framework. We follow the next-scale prediction paradigm of VAR [49], and introduce MoE layers to route tokens across scales, allowing them to adaptively select experts. During training, the outputs of the middle block in small and intermediate scales are aggregated to align with a pretrained visual encoder’s features.这张图概括 MEPA 的整体方法流程。阅读时先看模块之间传递的训练信号,再看作者如何把目标拆成可优化的子问题。
