English(EN) PivotMerge: Bridging Heterogeneous Multimodal Pre-training via Post-Alignment Model Merging

PivotMerge框架整合多模态大语言模型对齐能力

作者 PulseAugur 编辑部 · [1 个来源] · 2026-04-28 04:00

研究人员推出了一种新颖的框架PivotMerge，旨在整合不同多模态大语言模型（MLLMs）的跨模态对齐能力。该方法解决了预训练模型合并中的挑战，特别是跨域参数干扰和对齐中层贡献不均的问题。PivotMerge利用共享空间分解和过滤，以及对齐引导的层级合并，来有效地结合这些专家模型。在多模态基准测试上的实验表明，PivotMerge在桥接异构预训练方面优于现有方法。 AI

影响引入了一种合并预训练多模态模型的新方法，有望提高效率和能力整合。
