中文简介:
我们提供了一个规则化的多集核扩展,正交procrustes问题,或超对齐。我们的新方法称为核超对齐,它扩展了超对齐的范围,包括非线性相似性度量,并使具有大量基本特征的多个数据集能够对齐。由于直接应用于fmri数据分析,内核超对齐非常适合于大ROI的多主题对齐,包括整个皮质。我们利用真实世界的多学科功能磁共振数据进行了实验。
课程简介: We offer a regularized, kernel extension of the multi-set, orthogonal Procrustes problem, or hyperalignment. Our new method, called Kernel Hyperalignment, expands the scope of hyperalignment to include nonlinear measures of similarity and enables the alignment of multiple datasets with a large number of base features. With direct application to fMRI data analysis, kernel hyperalignment is well-suited for multi-subject alignment of large ROIs, including the entire cortex. We conducted experiments using real-world, multi-subject fMRI data.
关 键 词: 内核扩展; 非线性相似措施; 磁共振成像
