FlatClip 方法复用图像模型进行 fMRI 学习

研究人员开发了 FlatClip,一种利用冻结的图像基础模型从 fMRI 数据中学习表示的新颖方法。该方法将皮层活动映射到与解剖结构相关的扁平地图,并使用 SigLIP2 编码器提取特征,仅需轻量级的下游探针进行训练。在某些基准测试中,FlatClip 相较于 ROI 级别的基线方法表现出竞争力,并强调了皮层排列和输入区域选择对于有效 fMRI 分析的重要性。 AI

影响 该方法为在神经科学研究中利用预训练图像模型提供了一种新途径,有望加速大脑活动分析的发现。

    FlatClip:通过皮层扁平图利用图像基础模型进行fMRI表征学习

    arXiv:2609.31204v2 Announce Type: replace-cross Abstract: Can the spatial organization of cortical activity help transfer frozen image representations to fMRI prediction? We introduce FlatClip, which renders cortical activity as anatomy-linked flatmaps and extracts features with …
