Abstract: In this paper, we present the concept of a “shape manifold” designed for reduced order representation of complex “shapes” encountered in mechanical problems, such as design optimization, springback or image correlation. The overall idea is…

Abstract: Consider a sample of $n$ points taken i.i.d from a submanifold $\Sigma$ of Euclidean space. We show that there is a way to estimate the Ricci curvature of $\Sigma$ with respect to the induced metric…

DOI: 10.1016/j.neucom.2019.11.014
Abstract: Abstract In real-world applications, the variation between multi-view data points, which should belong to the same cluster, is larger than the variation between data points belonging to different clusters. This results in instability of most…
