WebApr 12, 2024 · Metavalent bonding has attracted immense interest owing to its capacity to impart a distinct property portfolio to materials for advanced functionality. Coupling metavalent bonding to lone pair expression can be an innovative way to propagate lattice anharmonicity from lone pair-induced local symmetry-breaking via the soft p-bonding …
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. WebAnalysis of principal nested spheres provides an intuitive and flexible decomposition of the high-dimensional sphere and an interesting special case of the analysis results in finding …

WebAs a backward stepwise approach, composite Principal Nested Spheres, which generalizes PCA, is proposed. In an example describing the motion of the lung based on CT images, we show that composite Principal Nested Spheres captures landmark data more succinctly than forward PCA methods. Keywords.

WebHowever, several widely-used Mercer kernels map data to a Hilbert sphere in RKHS. 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. lam dung tin nhiem chiem doat tai sanWebThe sphere Ak is called the k-dimensional principal nested sphere and is a submanifold of the higher dimensional principal nested spheres.
