新的贝叶斯框架在科学数据中对齐几何与功能

研究人员开发了一个名为 Domain Elastic Transform (DET) 的新概率框架,旨在对齐高维科学数据中的几何与功能。这种无网格方法将数据视为不规则域上的函数,能够直接配准高维信号,无需体素化。DET 将域变形建模为由联合空间-功能似然引导的弹性运动,以无监督方式运行,并通过采样点配准和位移插值进行扩展。在 MERFISH 小鼠大脑切片和 Stereo-seq 小鼠胚胎图谱上的评估表明,DET 与其他管道相比具有更优越的空间重叠和拓扑结构,其加速的 PASTE2 变体实现了高标签转移准确性。 AI

影响 这种新方法可以改进复杂科学数据集的分析,可能加速基因组学和神经科学等领域的发现。

    Domain Elastic Transform: Bayesian Function Registration for High-Dimensional Scientific Data

    arXiv:2603.21235v2 Announce Type: replace Abstract: Nonrigid registration is conventionally divided into point set registration, which aligns sparse geometries, and image registration, which aligns continuous intensity fields on regular grids. This dichotomy is limiting for emerg…
