主测地线分析(英语:Principal Geodesic Analysis)是经典主成分分析(PCA)的一种扩展,适用于在黎曼流形上取值的数据。本文提出了一种精确计算旋转群SO(3)上数据的PGA的新算法。通过对模拟数据和真实的数据的测试,说明了该算法的一些性质,并讨论了其可能的应用。
PGA, or Principal Geodesic Analysis, is an extension of the classical PCA (Principal Component Analysis) to the case of data taking values on a Riemannian manifold. In this paper a new and original algorithm, for the exact computation of the PGA of data on the rotation group SO(3), is presented. Some properties of this algorithm are illustrated, with tests on simulated and real data, and its possible applications are finally discussed.
