WebThese features are achieved by deforming tori into spheres with self-gluing and then using a variant of the recently developed principal nested spheres analysis. This PCA analysis involves a step of subsphere fitting, and we provide a new test to avoid overfitting. We validate our torus-PCA by application to an RNA benchmark data set. Webspheres by choosing a nearby statistically benign geometry with clever mapping and self-gluing and then use a modiﬁcation of the recently developed principal nested spheres analysis (PNS) of Jung, Dryden and Marron (2012). In particular, this PNS analysis involves a step of small sphere ﬁtting and we provide a new test to avoid overﬁtting.

For such directional data in RKHS, linear analyses can be unnatural or suboptimal. Hence, we propose an alternative to kPCA by extending principal nested spheres (PNS) to RKHS without needing the explicit lifting map underlying the kernel, but solely relying on the kernel trick.
