Volume extrapolation via eigenvector continuation

چکیده
We develop an extension of eigenvector continuation (EC) that makes it possible to extrapolate simulations quantum systems in finite periodic boxes across large ranges box sizes. The formal justification for this approach, which we call finite-volume (FVEC), is provided by matching functions at different As concrete FVEC implementation use a discrete variable representation based on plane-wave states and present several applications calculated within framework.

Features Selection via Eigenvector Centrality
In an era where accumulating data is easy and storing it inexpensive, feature selection plays a central role in helping to reduce the high-dimensionality of huge amounts of otherwise meaningless data. In this paper, we propose a graph-based method for feature selection that ranks features by identifying the most important ones into arbitrary set of cues. Mapping the problem on an affinity graph...
متن کاملBayesian contour extrapolation: Geometric determinants of good continuation
We investigated whether observers use rate of change of curvature in visually extrapolating contour shape. Arcs of Euler spirals with positive or negative rate of change of curvature gamma (hence linearly increasing or decreasing curvature) disappeared behind the straight-edge of a half-disk occluder. Observers adjusted the position and the orientation of a line probe around the curved portion ...
متن کامل8.1 Continuation of Volume Estimation
In the past two lectures, we have been analyzing the construction of an f.p.r.a.s. to estimate the volume of a convex body K ⊆ R in the membership oracle model. We assumed a general upper bound on the mixing time of heat-bath ball walks, and used this assumption to analyze our construction. In this section, we prove the assumed bound. Recall that the Poincaré constant is defined by α = infφ:K→R...
متن کاملImplementing regularization implicitly via approximate eigenvector computation
Regularization is a powerful technique for extracting useful information from noisy data. Typically, it is implemented by adding some sort of norm constraint to an objective function and then exactly optimizing the modified objective function. This procedure often leads to optimization problems that are computationally more expensive than the original problem, a fact that is clearly problematic...
متن کاملContinuation of Point Clouds via Persistence Diagrams
In this paper, we present a mathematical and algorithmic framework for the continuation of point clouds by persistence diagrams. A key property used in the method is that the persistence map, which assigns a persistence diagram to a point cloud, is differentiable. This allows us to apply the Newton-Raphson continuation method in this setting. Given an original point cloud P , its persistence di...
