Immersive Analytics: A User-Centered Perspective
Proceedings of the 27th ACM Symposium on Virtual Reality Software and Technology, 2021Researchers have explored using VR and 3D data visualizations for analyzing and presenting data for several decades. Surveys of the literature in the field usually adopt a technical or systemic lens. We propose a survey of the Immersive Analytics literature from the user’s perspective that relates the purpose of the visualization to its technical ...

An Evolutionary Analytic Center Classifier
2020Classification is an essential task in the field of Machine Learning, where developing a classifier that minimizes errors on unknown data is one of its central problems. It is known that the analytic center is a good approximation of the center of mass of the version space that is consistent with the Bayes-optimal decision surface.

Analytic Center Manifolds of Dimension One
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1986AbstractThe flow of a system of ordinary differential equations near an equilibrium point is completely determined by the flow restricted to a corresponding center manifold. Even for analytic equations center manifolds need not be analytic and therefore, in general, the flow on a center manifold cannot be described by an analytic equation.

Applications of Analytic Centers
1991In this paper we present some applications of a recently introduced concept, the ”analytical center” of a convex inequality system. Let F = {f a (x, p)} denote a family of functions depending on parameters p ∈ P and elements a of an index set A, which are concave in x ∈ X, on the sets S a,p where they are nonnegative.

Center and isochronous center problems for quasi analytic systems
Acta Mathematica Sinica, English Series, 2008Consider the planar quasi-analytic systems \[ \begin{aligned} {dx\over dt} &=\delta x- y+ \sum^\infty_{k=2} (x^2+ y^2)^{(k-1)(\lambda- 1)/2}X_k(x,y),\\ {dy\over dt} &= x+\delta y+ \sum^\infty_{k=2} (x^2+ y^2)^{(k-1)(\lambda- 1)/2} Y_k(x, y),\end{aligned} \] where \[ \begin{aligned} X_k(x, y) &= \sum_{\alpha+\beta= k} A_{\alpha\beta} x^\alpha y^\beta,\\

The Penalized Analytic Center Estimator
Econometric Reviews, 2015In a linear regression model, the Dantzig selector (Candes and Tao, 2007) minimizes the L1 norm of the regression coefficients subject to a bound λ on the L∞ norm of the covariances between the predictors and the residuals; the resulting estimator is the solution of a linear program, which may be nonunique or unstable.

Immersive Human-Centered Computational Analytics
2018In this chapter we seek to elevate the role of the human in human-machine cooperative analysis through a careful consideration of immersive design principles. We consider both strategic immersion through more accessible systems as well as enhanced understanding and control through immersive interfaces that enable rapid workflows.

Analytic two-center exchange integrals
Chemical Physics Letters, 1973Abstract A highly accurate exact analytical expression for two-center electron-repulsion integrals of the exchange type using normalized Slater orbitals has been developed. Numerical results are presented.
